SME products have been designed and developed utilising many years of operating and service experience with submersible motors and subsea motors. SME are a quality assured company and are certified to ISO 9001 by SGS for “Design, development, manufacture and testing of submersible subsea electric motors”. SME produce their motors under a rigorous QA procedure to ensure that all motors are supplied in a “Quality and Reliability Assured” condition. In addition to ensuring the motors are supplied in excellent condition, SME believe it is their responsibility to try to ensure that the end users get many years of reliable life from their SME motors.
At SME we try to help the end user – not just sell them a motor in a box. We offer the services of experienced commissioning engineers to go to site and ensure the motors are installed, commissioned, and protected correctly. We also offer full 24 hour service and testing facilities. At SME we are continually working to improve the performance of our products and for this reason we reserve the right to make changes without notice to any of the data in this brochure. Please contact us direct for confirmation of any drawings dimensions or performance data.
SME SUBSEA MOTORS SME can design and build Subsea motors to suit any requirements, due to our totally flexible design capabilities: Flexible External Dimensions to suit all applications. Dimensions to allow drop in replacement of existing units. Anodised aluminium, or, 316 stainless steel or more exotic materials, such as Duplex. Power drive to load using an output shaft with a standard coupling, or, close coupled. Single drive shaft, or, a drive shaft at both ends, double shaft extension. SME can design and build a motor with a completely new lamination to meet special design requirements, if necessary. SME design their motors so they do not run hot. Typical motors can run on deck for at least ten minutes on full load, with no cooling, without overheating. The motors are designed to be compact in size and suitable for heavy-duty applications, like trenching.
If weight is important, SME can design the motor for minimum weight by utilising an aluminium construction and a hollow motor shaft, while still ensuring the motor is generously rated for full load operations. If the motor is going to drive a hydraulic pump we recommend a close-coupled arrangement to save the weight of the coupling and the coupling housing. SME can design and build motors for all voltages from 24 volts to 6600V with 50Hz or 60Hz frequencies, or for VVF requirements. High Voltage motors can have random wound stator windings, or formed coils, depending on space and weight constraints. The winding wire for the High Voltage motors is double insulated and passes a twisted wire test at 16,000 volts and is rated up to 155 Deg.C. All windings are designed to keep ‘turn to turn’ voltage to a minimum. All winding materials and cables are specially selected to be suitable for use in hydraulic oils. In general, SME Subsea motors have low loss lamination steel (3 watts/kg), which allows for higher flux densities, and less heat, with less materials and weight. All motors are oil filled and we recommend hydraulic oils for good lubrication characteristics in preference to electrical oil ( which has better di-electric capabilities, but worse lubrication capabilities). If motors are going to drive a water pump, SME can design the motor to take the thrust load from the pump and keep the sea water out of the motor with a single or double mechanical seal arrangement. Small thruster motors can be designed and built for voltage/speed control, which is a relatively simple speed control system and can be built with a thrust bearing incorporated to take the thrust load from the impeller.
To ensure the integrity of the motor housing, SME does not use castings. All components are machined from solid or from extrusions. The external aluminium components are typically 6061 T6 marine grade aluminium and hard anodized to a military specification.
All ball bearings are from well known brands such as SKF, FAG, or NSK. Oil seals are high temperature and typically made from Viton. Mechanical seals are typically Burgmann. All hardware used on SME Subsea motors is 316SS. All fixing holes are blind. Oil in and out fittings and the stator pack-fixing bolt, if applicable are sealed with O rings.
The preferred power cable entry system for SME motors is to use an “oily tube” connected to an adaptor, which is part of an oil tight rubber gland that is fixed to the stator frame. SME do not recommend bringing the power cables through the end-shields of the motor as this creates additional complications when the motors are stripped down during service (because the end-shields cannot be readily removed from the stator). Subsea connectors can be offered as an alternative to the Oily Tube if requested.
SME strongly recommend that the motors are fitted with PT100s fitted in the windings and also to the bearings. The internal motor temperatures are monitored and set up to alarm if the temperatures rise above a safe temperature. SME can also offer additional protection with a water detector. The auxiliary connections for PT100s, can be made through standard high pressure, water tight, plug and sockets as, supplied by “Subconn”, “Impulse”, and “Burton”. These are also fitted to a connection block on the stator, not on the end shield. All finished motors are pressure tested to ensure they are “oil tight” and suitable for compensated operation down to 4000 metres. All motors are rated for continuous operation and all prototype motors are full load performance tested at rated voltage and rated frequency to confirm their performance characteristics. All motors can be issued with a “Type Test Certificate” or even full load tested at additional cost, if required.
SME can offer to arrange for hydraulic pumps to be set up and tested on the motors at rated voltage and frequency. SME can offer to supply Hydraulic Power Units, “complete”, with the addition of customer specified Hydraulic Pump. SME Subsea motors can be designed and built for all subsea applications, such as ROVs, Trenchers, Ploughs, Submarines and Dredges. All brands of Subsea motor can be serviced, repaired and tested by SME. In some cases the original motors can be significantly upgraded. If you are having problems with your existing Subsea motor please contact SME – we are ready and able to provide assistance and we are very price competitive.
APPLICATIONS Driven equipment can include: Hydraulic Pumps: For ROV Hydraulic Power Units, Subsea Robotics, Thrusters, etc. Water Pumps: For Jetting Systems, Hull Cleaning, Trenching and Pipe and Cable Laying Equipment, Pipe Pressurisation, Dredging, etc. Propellers/Impellers: For Remotely Operated Vehicle Thrusters, Manned Submarine Thrusters, Mass Flow Excavation, etc. Gearboxes: For Subsea Winches, Cable Tensioners and De-reelers.

INSTRUMENTATION SME Subsea Motors are available with a range of instrumentation: Bearing and Winding Temperature Monitoring Water Ingress Detection Pressure Transducer Resolvers and Encoders Tachometers
COOLING Motors are generally designed to operate with no additional cooling other than the ambient water temperatures but in some cases external cooling may be required. SME can provide motors with closed loop cooling circuits or motors that are suitable for use with externally fed cooling circuits.
ELECTRICAL CONNECTIONS SME Subsea Motors use an oily tube termination for all power connections as standard. However, appropriately sized and rated Subsea connectors can be used as an alternative, either a Bulkhead Connection on the motor, or as part of a fixed Flying Lead Termination. Instrumentation is generally terminated using a variety of Subsea Connectors. Customers are free to specify their Connectors of choice.
MECHANICAL INTERFACE Motors are design built to suit the application and SME can supply a broad range of interfaces from direct coupled arrangements to the use of separate coupling housings. SHAFTS: Female and Male Spline Shafts, Internal and External Keyed Shafts. FLANGES: NEMA, IEC, SAE, DIN Standards are all available as well as unique requirements. Motors can be provided with Double Ended Arrangements to drive multiple loads.
MOTOR MOUNTING Motors can be provided with various Mounting arrangements including Feet, Flanges, Brackets, or Clamping. In most cases SME can match the mounting interfaces of units being replaced to ensure ease of installation in existing equipment. Motors can be manufactured for Horizontal or Shaft Up or Down installation.
COMPENSATION REQUIREMENTS Motors are built to utilise external compensation. Motors are fitted with oil in and out ports as well as several bleed points to facilitate easy plumbing. Fittings can be provided with BSP, NPT or JIC and other fittings with both straight and tapered threads to provided uniformity on the installation. There are a vast range of acceptable compensation fluids and SME can provide advice in the suitability of various oils.

We can offer the following motor, SME ROV10-4, 30kW, 4 Pole, 1500rpm, 380/3/50, Aluminium Construction Subsea Motor to Drive Hydraulic Pump, Epoxy coated for protection.
Heat Exchanger Motors.
We now offer a complete range of water filled, watertight, submersible subsea motors with integral heat exchangers in 10-inch, 12-inch, 14-inch and 16-inch size for 2 pole and 4 pole speeds.
These subsea motors offer a significantly lower temperature rise when compared with standard submersible subsea motors. This is an advantage that can be utilized when customers want to operate in water with a high ambient temperature, or when there will be minimal cooling water flow available. Even with the standard applications the lower temperature rise will extend the life of the motor significantly. There is an accepted rule of thumb for electrical insulation that its life is shortened by one-half for every 10°C increase in operating temperature. The winding operating temperature for a normal water filled submersible motor is about 70 degrees.C, in 25 degree.C water. However an SME Heat Exchanger Motor will be running at about 45 degree.C. (This is 25 degrees cooler). This magnitude of difference in temperature rise will have a significant positive impact on motor life.
The basic design principle for these subsea motors is to circulate the internal water in the motor remove the heat from the "active" parts of the motor, and then pass it through a heat exchanger which brings the internal water back to somewhere close to the external ambient water temperature - before feeding it back through the "active" parts again to remove more heat. The heat exchanger increases the external surface area of the motor by 50% and the water circulation allows the heat to dissipate more evenly and quickly out of the subsea motor and into the external water. The small impeller inside the subsea motor that circulates the water has an insignificant impact on the motor efficiency in terms of additional load, while the subsea motor has an improved efficiency because the stator and rotor copper losses are reduced due to the lower operating temperature.
Motor Thermal Protection Unit
All SME Heat Exchanger Motors come with four (4) PT100 temperature sensors installed in the motor. One PT100 is attached to the thrust bearing assembly that will detect excessive thrust loads and overheating in the thrust bearing. One PT100 is installed in the end winding on the non-drive end of the motor. One is installed half way down the slot in the winding in the middle of the motor. One is installed in the end winding on the drive end of the motor.
SME can offer one temperature protection unit (SME4TM) to monitor all four PT100'S installed in the Heat Exchanger Motor.
Water Pump Motors. Our water pump motors are not vertically oriented, water filled, down hole pump motors, as has previously been the norm throughout the subsea industry. Silvercrest / Submersible Motor Engineering motors are substantial oil filled submersible motors, designed to run in the horizontal axis with a large thrust bearing assembly to withstand water pump loads. We can offer specially designed turbine pumps to match our motors. Again these pumps are not the usual vertically oriented type, these are specifically designed with a twin bearing arrangement, for use in the horizontal axis. Thus dramatically extending operational life and improving pump reliability. Silvercrest recently delivered ten 260kW, 3000VAC, double ended, 2 pole, stainless steel bodied motors to CTC Marine Projects Ltd. The motors will be used by CTC on their subsea plough and trenching vehicles worldwide. This was a bespoke order that was completed in six weeks from receipt of order, ex-works from our manufacturing facility in Australia. The 260kW/ 3000V / 60Hz / 2 pole pump motors (designed specifically for use in the horizontal axis) were fitted with shafts at both ends, in order to mate with three tandem mounted hydraulic pumps on one end and a Hayward Tyler M6 single stage water pump-set on the opposite end. In this 260kW model, rather than using the pivot shoe arrangement, typical of vertically oriented pump-sets, heavy duty tapered roller bearings were fitted to the rotor to manage the water pump induced end-loads. Thus giving a calculated bearing life in excess of 11,000 hours, even when used in the horizontal axis. Depth rating on each motor is 10,000 meters, with oil filled compensation. Motor housings are 316 stainless steel, with Mylar coated windings (the ultimate in winding coating technology) being used in each motor at the request of CTC, giving an insulation rating of >16kV at a temperature of 140 degrees C.
Rov and Subsea Plough and Trencher Motors. Silvercrest offer an established range of Rov motors ranging from 5HP to 500HP. All of these motors are available in either SS316 or Hard Anodized Aluminium finish. We will also design and build submersible motors to suit your individual requirements and subsea project. Our motors are in use with most of the major operators worldwide such as Saipem, SMD Hydrovision, Sonsub, CTC Marine Projects, Impresub, Fugro, Thales, MTQ, LD Travocean and Canyon Offshore.

Motor-pump sets (depth rated to 3000m) for subsea trenching operations. Silvercrest / Submersible Motor Engineering has recently manufactured and supplied two 265kw motor-pump sets for SMD-Hydrovision (England). The package comprised 265kw subsea motors, 2-pole, 3000v, 3ph, 60hz. Together with Jetting Pumps (wet end only, operating at 2-pole, 60 hertz). The motors were a stainless steel construction, and the pumps Zinc Free Bronze. These motor-pump sets will be installed onto one of the world’s largest subsea trenching vehicles. In addition, Silvercrest / Submersible Motor Engineering has manufactured and delivered in just eight weeks from order, two water turbine pumps to CTC Marine Projects based in Teeside (England). The pumps will be used by CTC, in conjunction with Silvercrest / Submersible Motor Engineering submersible 260Kw motors, on their subsea plough and trenching vehicles worldwide.
The two Silvercrest SH-M6R submersible pumps with a 231mm OD impeller and a nominal operating speed of 3600rpm will be used as an alternative to the Hayward Tyler model M6-1 stage CI/BR/SS submersible pump. The Silvercrest pump although matching the performance of the Hayward Tyler unit, is specifically designed for horizontal operation providing a greatly increased reliability for use in horizontal and downward angled operation.

The female spline can be manufactured to mate with the supplied pumpset. Our purpose built pump motors are designed specifically for use in the horizontal axis. Unlike a down hole pump motor such as the HT Sumo, our motors do not use pivot shoe thrust assemblies. As a result our motors are compensated for depth pressure using oil rather than distilled water as in the case of down hole pump motors. Unlike most motor manufacturers, we manufacture our own core laminations on site, affording maximum flexibility in design. We can bespoke manufacture virtually any shape of motor you may require. In this 260kW model, rather than use the pivot shoe arrangement, we fit heavy-duty tapered roller bearings to the rotor to manage the water pump induced end loads. Thus increasing the reliability and service life of the motor by a factor of 10 or more when used in the horizontal axis. Our superior Mylar coated windings are the ultimate in winding coating technology. Mylar coated windings have an insulation rating of >16kV at a temperature of 140 degs C. No other winding coating even comes close to this standard. We can offer you submersible motors with the following specification:-

MANNED WET and DRY SUBMARINE PROPULSION SYSTEMS. Historically, over the last fifteen years electrical submarine thruster systems have been problematic. Notably AC motor controllers and DC brush motor powered thrusters have been the cause of many a company’s downfall. Other problems such as 120VDC battery buss voltages have compounded the overall problem. Since the early tourist submarines first came into use during the mid 80’s, motor controller technology has steadily developed. Certain manufacturers have produced systems which have proven to be more capable and more importantly, reliable than their early counterparts. Unfortunately, this leaves quite a few of the older tourist and research submersibles struggling with the older unreliable systems that are still in use. A little known fact is that motor drive systems have a finite operating life, indeed they have a ‘shelf life’. This is due to the deterioration of the large capacitors used in the drive controllers. This occurs even when the drive is not in use. If a drive is more than five years old, then it’s capacitors are already approaching the end of their useful life. As a result these drives are now becoming tired and often prone to failure. Usually with accompanying pyrotechnics! Silvercrest can offer a new ‘replacement’ propulsion system for both new build and existing manned submarines. We tailor the installation to solve your propulsion requirements. Once the problems have been identified and assessed, where needed, we will re-design your battery buss arrangement to produce a working voltage suitable to run a reliable and powerful thruster system. We will then design the motors specifically to meet your requirements. The pressure compensation system is added and the final stage of the design process is matching the correct drive with your new motors.
Recently Silvercrest completed the installation of our 69kW (6 x 11.5kW) AC propulsion and ballast system into one of the Odyssey class tourist submarines in south-east Asia. The system utilizes a state of the art, purpose built, 11.5kW thruster / ballast pump motor. A custom built submersible, 3 phase, AC, squirrel cage induction motor encased in a 316 Stainless Steel compensated housing. The motor was designed specifically to match the available buss voltage and it’s dedicated motor invertor controller. The Silvercrest motor is smooth, quiet and powerful. Motor control is supplied through a CT Commander SE invertor controller drive. Manufactured by one of the leading drive manufacturers in the world today. Each drive utilizes digital control using an onboard processor with EEPROM data storage. This allows the drive to store operating parameters and its own operating history for maintenance and fault diagnosis purposes. A twin Burgmann tandem mechanical shaft seal arrangement, fitted on each motor shaft, provides protection from water ingress. This works in conjunction with a custom built 33 Lt capacity oil-filled central motor compensation system. Great attention has been applied to designing our motor systems for reliability and a long working life. All components are rated to at least 150% of required working capacity. This over rating of individual components ensures that no single part of the system can ever be overloaded during correct use. Specific motor functions and operational profiles can be catered for and programmed into the CT controller. For example the Odyssey system has a ‘Turbo’ function, whereby the motors run normally with a 7.5kW max output. Then at the flick of a switch on the pilot’s console, the motor can be enabled to output it’s maximum 11.5kW (for 1½ minutes) for use in maneuvering emergencies.
Motors of various ratings are available from Silvercrest/SME, utilizing many of the same frame parts. For example our 15kW motor utilizes the exact same parts as the 11.5kW unit, but with more motor laminations and therefore a slightly longer body. This reduces your spares requirement even when mixing and matching the motor sizes. Military spec versions of the motors are also available on request.
Small Thrusters built for a manned submersible.
Silvercrest / SME delivered in twelve weeks from placement of order, a complete new thruster system for a dry-transfer submarine.
SME 10kW / 160VAC (inverter controlled - 240VDC supplied) thruster.
OVERVIEW. The new propulsion system is 240VDC based, using a 6-pole motor with its invertor drive programmed for maximum frequency output of 40-45 Hz. Using a directly driven motor to propeller configuration, this relates to a top speed of 900RPM. The thruster nozzle and propeller were designed for optimum performance at this speed, with as linear a performance profile as possible.
In order to improve the reliability of the system and to reduce motor, invertor and associated cabling sizes, the battery buss voltage from each battery pod was connected in series via a new purpose built 240VDC distribution panel. As the supply to the inverters was derived from a battery, the issue of supply frequency was not a concern. Therefore we opted for 50Hz inverter units as these are more ‘standard’ and therefore more readily available and cheaper. Silvercrest/SME controller specialists carried out the initial invertor installation and commissioning of the motors and controllers. During installation the motor controller sets were ‘dynamometer’ tuned using an in-built optimization facility. The controllers can then be either generically programmed for use in any location or individually in-situ programmed to provide optimum operating performance for each given motor operating position. For motor speed control signals into the inverter, the simplest option, from a fault finding and maintenance point of view, was to provide an analog voltage signal (+10VDC to -10VDC). This option required a small interface bi-directional interface PCB that was mounted directly on the face of the controller. We have used this option on other manned submarine applications with excellent results. The propellers and nozzles were custom designed for each application, using computer 3D modeling to analyze the CFD of our designs to visualize and adjust operating profiles. As a result we are able to design for optimum performance and efficiency.
(Example:- Finished 3 blade results).
SPECIFICATIONS FOR SUBMERSIBLE MOTOR ENGINEERING SUBSEA ELECTRIC MOTORS.SILVERCREST can design and build SUBSEA motors to suit most requirements, due our totally flexible design capabilities.
Flexible External Dimensions to suit all applications. Dimensions to allow drop in replacement for existing units. Anodised aluminium, or 316 stainless steel construction. Power drive to load using an output shaft with a standard coupling, or close coupled. SUBMERSIBLE MOTOR ENGINEERING can design and build a motor with a completely new lamination to meet special design requirements, if necessary. SUBMERSIBLE MOTOR ENGINEERING design their motors so they do not run hot. Typical motors can run on deck for at least 10 minutes on full load, with no cooling, without overheating. The motors are designed to be compact in size and suitable for heavy-duty applications, such as subsea trenching.
In general the SUBMERSIBLE MOTOR ENGINEERING subsea submersible motors have low loss lamination steel (3 Watts/kg), which allows for higher flux densities, and less heat, with less material and weight. All fixing holes are blind except the "oil in" and "oil out" fittings and the stator pack fixing bolt, if applicable. SUBMERSIBLE MOTOR ENGINEERING strongly recommend that the motors are supplied with PT100s fitted in the windings and also in the bearings and that the internal motor temperature. SME can also offer additional protection with a water detector. The auxiliary connections for PT100s, can be made through standard high pressure, water tight, plug and sockets as supplied by "Subconn", "Impulse", and "Burton". These are also fitted to a connection block on the stator, not on the end shield. All motors are rated for continuous operation, and all prototype motors are full load performance tested at rated voltage and rated frequency, to confirm their performance characteristics. All motors can be issued with a "Type Test Certificate" or even full load tested at additional cost, if required.

ELECTRIC MOTORS FOR SUBSEA MINING. Submersible Motor Engineering are a leading supplier of Electric Motors for subsea applications such as ROVs, TMS units, HPUs, Subsea Trenching machines, and Subsea Ploughs.
SUBMERSIBLE MOTOR ENGINEERING was recently awarded a contract to design and build a set of electric motors for a Subsea Mining project which is understood to be the first deep water Subsea mining project in the world. The motors will have to operate at up to 2,000 metres depth, and will be subject to continuous heavy vibration of up to 10 mm/s and shock loading up to 10G. Due to the depth and the high power requirements it was decided the machines had to operate at 6600 volts to reduce the current in the long umbilical power supply cable.
SUBMERSIBLE MOTOR ENGINEERING commonly produce motors to operate at 3000, 3300, and 4160 volts, but 6600 volts posed some new challenges as we needed to design and build the motors with hot pressed formed coil stator windings. The shock and vibration requirements also required the selection of a very heavy duty bearing arrangement, which was reviewed by SKF to ensure the final design was more than capable of handling the required duty.
There are three different mining machines, and they require five different types of motors which drive the cutter heads, slurry pumps, and hydraulic power units, (HPUs). The cutter head motors are rated at 300kW and 600kW, 4 Pole. The slurry pumps at 330kW, 6 Pole, and 650kW 12 Pole. The HPU motors at 400kW 4 Pole. The motors were all full load dynamometer tested by SUBMERSIBLE MOTOR ENGINEERING. All of the motors except the HPU motors will operate with Variable Frequency Drives and these motors were dynamometer tested with the drives. All of this testing was undertaken with the customer at SUBMERSIBLE MOTOR ENGINEERING’s Maddington factory. All the motors have all been delivered to the customer.
18 inch AND 22 inch Motors. SUBMERSIBLE MOTOR ENGINEERING now produce 18 inch and 22 inch motors with 2 or 4 pole speeds. These motors are water filled and available with 2300, 3300, 4160, or 6600 volt windings. The thrust bearings are continuously rated at 7,700 kg (17,000 lbs).
SUBMERSIBLE MOTOR ENGINEERING recently supplied two motors rated at 625Hp, 4160 volts, 4 pole, which have a continuous thrust load of about 7,000 kg and a closed valve thrust load of about 10,000 kg. Prior to installation these motors and pumps were independently tested by S&N Pumps in Houston.
These motors can be supplied in 316 Stainless Steel or Duplex Stainless Steel. As with all the SUBMERSIBLE MOTOR ENGINEERING product range, these motors are also available with SUBMERSIBLE MOTOR ENGINEERING’s Heat Exchanger cooling system to ensure the motors are suitable for the most demanding applications.
SUBMERSIBLE MOTOR ENGINEERING now offer 6”, 8”, 10”, 12”, 14”, 16”, 18” and 22” motors as standard and stock motors up to 16” in Perth at our factory.
WD MOTORS. SUBMERSIBLE MOTOR ENGINEERING have been producing their range WD “sump pump” motors for many years to cover a broad range of submerged pumping applications. The WD range from SUBMERSIBLE MOTOR ENGINEERING offers a motor that is suitable for an extremely broad range of uses. The mechanical interface can be designed to match many different types of pumps. These motors has been designed to operate as a wet motor, either in a sump or mounted in a manifold, or as a dry motor with a water jacket feed from the pumped liquid.
A recent customer had an existing pumping station on a river bank in Queensland. He needed a motor that could be fitted to the existing pumps. The original pumps were flooded regularly which caused the air cooled motors to fail. The new motors were required to operate in a dry environment most of the time, but to also be able to operate during the regular floods that occurred at the site. SUBMERSIBLE MOTOR ENGINEERING provided three 150kW, 4 Pole, WD motors fitted with a water jacket to allow long term reliability in an ambient that regularly reaches in excess of 40 Deg C. The Water Jacket was fed by a small bleed from the Pump Discharge. These motors were installed on the pumps and were operating well despite being flooded several times in their first few months of operation. WD Motors are a very flexible product and SUBMERSIBLE MOTOR ENGINEERING can engineer these motors to solve many complex applications.
HIGH VOLTAGE SUBMERSIBLE MOTOR REPAIRS. SUBMERSIBLE MOTOR ENGINEERING design and manufacture large High Voltage Submersible Motors so we are quite capable of servicing and maintaining other brands of submersible motors. SUBMERSIBLE MOTOR ENGINEERING has repaired numerous Pleuger, Weir, Haywood Tyler, and Byron Jackson, high voltage sea water lift pump motors for some of the premier oil companies around the world.
SUBMERSIBLE MOTOR ENGINEERING is the service supplier of choice for Oil and Gas, Mining, and the Municipal Water Supply Industries, especially in Australia, New Zealand, and South East Asia. In most cases SUBMERSIBLE MOTOR ENGINEERING can offer and deliver a much quicker and cost effective repair than the original OEM.
SUBMERSIBLE MOTOR ENGINEERING can also provide full load pump testing to ensure the repaired motor will be reliable before it is re-installed.
SUBMERSIBLE MOTOR ENGINEERING can also offer on-site inspection, provision of on-site spares, training of staff about maintenance and maintenance issues, and commissioning staff during installations.
SUBMERSIBLE MOTOR ENGINEERING should be the first choice for the provision of Maintenance and Service of Submersible Electric Motors.
DYNAMOMETER LOAD TESTING. SUBMERSIBLE MOTOR ENGINEERING have increased their load testing capacity in Maddington with the acquisition of a new 2,500kW “water brake” dynamometer and additional high voltage transformers, switchgear, and instrumentation. SUBMERSIBLE MOTOR ENGINEERING can now provide a broad range of no load and full load testing at 50 or 60 Hz, and typical voltages of 2300, 3000, 3300, 4160, and 6600 volts. The extensive range of transformers and voltage regulators as well as multiple dynamometers means SUBMERSIBLE MOTOR ENGINEERING can ensure that new, and repaired, motors, are tested to ensure they meet any applicable requirements and specifications.
SUBMERSIBLE MOTOR ENGINEERING NEW OFFICE. SME have recently moved into bigger and better premises in Phoenix, Arizona. The new factory has 17,500 sq ft (1,622 m2) of space and has been set up to offer customers the repair and rewinding of submersible motors. There is a fully equipped machine shop, winding shop, and testing facility. The new building has a 600 amp power supply, so they can run large motors on no load.
SUBMERSIBLE MOTOR ENGINEERING carry a large stock of new submersible motors and plan to increase this in the near future.
PERMANENT MAGNET GENERATORS FOR TIDAL GENERATION. SUBMERSIBLE MOTOR ENGINEERING recently built a prototype subsea generator that was rated at 100kW, 40 Poles, (18 RPM), and 500 Volts. The generator is air filled as it is not expected to operate below 20 metres of depth, and weighed 4.5 tonnes fully assembled.
The generator was full load tested, which was quite complicated to organize, as we needed a 1.5 MW variable speed motor/drive and a 10:1 ratio gearbox that could handle the full load torque of approximately 60,000 Nm. The performance matched the design quite closely, with an efficiency of 86%, and a PF of 0.99. This generator was designed for very low speed operation to negate the need for a gearbox, however, SUBMERSIBLE MOTOR ENGINEERING now believe it is probably better to design the generator for a higher speed with a single stage gearbox.

SME – WD Series Motors – for Open Well or Sump Applications Submerged or not Submerged, Cast Iron, Steel, or Stainless Steel Construction.SME has many years experience in the manufacture of submersible motors and the WD series of motors have been designed for the toughest jobs to ensure reliability and a long service life. When conditions are extreme and performance is critical these motors deliver the quality and durability required. WD motors are designed for continuous operation in sludge, effluent, slurry, and other liquids – to a submergence of 10 metres, in an open well, a river bank, a tailings pond, or a sump. The motors are air filled, with a separate oil filled seal chamber to ensure robust sealing of the drive shaft. The WD Series motors can also be supplied with a large range of sealing options to ensure the motor is suitable for the most extreme conditions from a combination of lip seals, and/or mechanical seals, to complex cartridge seal arrangements. If the motors are going to be continuously submerged they will rely on the liquid they are submerged in for cooling. If they are not going to be submerged continuously – or only intermittently — they are designed with a water jacket for cooling and water is usually bled from the pump through the water jacket. These IP68 motors have been used in both vertical and horizontal applications driving a diverse range of pumps in many unique applications. The Motors can be supplied with an extensive array of flange and shaft dimensions to ensure the motors can be matched to a large range of different pumps. The motors can also be supplied with standard IEC and NEMA flange and shaft dimensions. The motors are very robust and designed to take the physical abuse on a typical mine site. They can tolerate overloads, and a lack of cooling. They can maintain full load operation for 15 minutes with no external cooling. These motors offer a robust alternative to other units that suffer from shorter operating lives – with no changes to the existing Wet end performance. These motors are fitted with moisture detection probes and PT100, or themiistor, thermal protection — as standard – and provided these are properly connected and set to give advance warning of problems these motors will give many years of reliable service in extreme applications.

SME – WD Series Motors.For Open Well or Sump Applications Submerged or not Submerged, With Cast Iron, Steel, or Stainless Steel Construction.SME has many years experience in the manufacture of submersible motors and the WD series of motors have been designed for the toughest jobs to ensure reliability and a long service life. When conditions are extreme and performance is critical these motors deliver the quality and durability required. WD motors are designed for continuous operation in sludge, effluent, slurry, and other liquids – to a submergence of 10 metres, in an open well, a river bank, a tailings pond, or a sump. The motors are air filled, with a separate oil filled seal chamber to ensure robust sealing of the drive shaft. The WD Series motors can also be supplied with a large range of sealing options to ensure the motor is suitable for the most extreme conditions from a combination of lip seals, and/or mechanical seals, to complex cartridge seal arrangements. If the motors are going to be continuously submerged they will rely on the liquid they are submerged in for cooling. If they are not going to be submerged continuously – or only intermittently — they are designed with a water jacket for cooling and water is usually bled from the pump through the water jacket. These IP68 motors have been used in both vertical and horizontal applications driving a diverse range of pumps in many unique applications. The Motors can be supplied with an extensive array of flange and shaft dimensions to ensure the motors can be matched to a large range of different pumps. The motors can also be supplied with standard IEC and NEMA flange and shaft dimensions. The motors are very robust and designed to take the physical abuse on a typical mine site. They can tolerate overloads, and a lack of cooling. They can maintain full load operation for 15 minutes with no external cooling. These motors offer a robust alternative to other units that suffer from shorter operating lives – with no changes to the existing Wet end performance. These motors are fitted with moisture detection probes and PT100, or themistor, thermal protection — as standard – and provided these are properly connected and set to give advance warning of problems these motors will give many years of reliable service in extreme applications.
Water Cooled Motors
SME design and manufacture a range of Water Cooled Electric Motors to provide a alternative to Standard Air Cooled Vertical Hollow and Solid Shaft Motors, these motors are for variety of line shaft turbine applications. The removal of the forced air cooling and replacement with a water jacket fed from the discharge of the pump ensures almost silent operation. This makes them uniquely suitable for pumping applications where noise is critical during operation. SME motors are robust and reliable in the toughest of environments.

STAINLESS STEEL MOTORS
Stainless Steel motors are required by the following industries:
TEMA Stainless Steel motors are designed and manufactured to operate in extreme conditions with high ambient temperatures, high humidity, water, and steam, etc. These motors are IP67 as standard and can run under water! All the motors are tested under water before they are shipped from the factory to ensure that they are completely air and water tight. The motors have a specially designed assembly arrangement which avoids the use of through bolts or endshield bolts. The outer surfaces of the motors are completely smooth to make it easier to clean and wash away any dirt or food scraps that might collect on them.
The motors can be manufactured in 302, 304, or 316 Stainless Steel. Standard motors are produced in SS304 for a long service life with no corrosion. The shafts are made from SS420 as standard.
The motors can be supplied in TENV (Totally Enclosed Non Ventilated) form with no fan, with fan cowl, or TEFC (Totally Enclosed Fan Cooled) with a fan and stainless fan cowl. The TENV motors are more popular as they are easier to clean. (It is difficult to clean under the fan cowl without removing it).
These motors can be supplied with IE2 (Eff1 or MEPS2) or IE3 Efficiency levels and have been tested to IEC60034.2.1:2007 Method A.
These motors have also been tested and certified by CSA for sale in North America and comply with the requirements for Premium Efficiency. The motors have a low temperature rise. Typically the external temperature for an SSP802-4 0.75kW TENV motor will be less than 60 Deg.C. after one hour on full load, and a TEFC motor will be less than 50 Deg.C.
All motors with a connection box are supplied with 150 Deg.C. thermistors in the windings. The motors without a connection box do not have thermistors.
All the motors are suitable for use with Invertors, and can be wound with special Inverter duty wire if requested.
The motors are available in standard IEC frames from 63 to 160 in B3, B5, B35, and B14 configurations. The standard B3 foot mount motors can be easily modified to B5 or B14 for coupling to a suitable gearbox. The motors can also be produced to fit special OEM non standard gearboxes such as SEW and Flender.
The standard Foot mount B3 motor can be easily modified to B3/B5 or B3/B14 by adding a separate flange ring. Likewise a B5 motor can be quickly and easily modified to be B14.
The motors are fitted with special NTN Blue Seal bearings, as standard, which are suitable for a very wide range of temperatures with very low friction losses. The drive end is sealed with two modified PTFE oil seals, with a very low friction coefficient, and the shaft is induction hardened to ensure a long service life.
All motors are fitted with one metre of cable, and tested under water as part of the standard routine testing of these motors. Provided that the connection box lid is not removed after the motors are shipped TEMA can guarantee that the motors are completely air and water tight. This means that condensation will not be able to form inside the motors, and that water, or steam, will not be able to enter the motors.
Stainless Steel motors are more expensive than standard cast iron or aluminium frame motors, but we are sure that the TOTAL COST OF OWNERSHIP for these motors is much less than standard motors. Standard motors do not last very long when subjected to steam cleaning or hot water chemical cleaning every day. When the motors fail the cost of the downtime and lost production can often be much more than the extra cost of a Stainless Steel motor.
The expected life of a Stainless Motor is at least 15 years, so these motors should never fail under normal operating conditions, while a standard motor might only last 6 months.
Standard motors are usually painted and it is not uncommon for flakes of paint to break free, when the motor starts to corrode, and contaminate the food being processed. This is another advantage of stainless steel motors. There is no paint to break off.
Pictures show our stainless steel motors working at food processing plants.

Please contact us direct for confirmation of any drawings dimensions or performance data.
SME SUBSEA MOTORS
SME can design and build Subsea motors to suit any requirements, due to our totally flexible design capabilities:
Flexible External Dimensions to suit all applications. Dimensions to allow drop in replacement of existing units. Anodised aluminium, or, 316 stainless steel or more exotic materials, such as Duplex.
Power drive to load using an output shaft with a standard coupling, or, close coupled. Single drive shaft, or, a drive shaft at both ends, double shaft extension.
SME can design and build a motor with a completely new lamination to meet special design requirements, if necessary.
SME design their motors so they do not run hot. Typical motors can run on deck for at least ten minutes on full load, with no cooling, without overheating. The motors are designed to be compact in size and suitable for heavy-duty applications, like trenching.
If weight is important, SME can design the motor for minimum weight by utilising an aluminium construction and a hollow motor shaft, while still ensuring the motor is generously rated for full load operations. If the motor is going to drive a hydraulic pump we recommend a close-coupled arrangement to save the weight of the coupling and the coupling housing.
SME can design and build motors for all voltages from 24 volts to 6600V with 50Hz or 60Hz frequencies, or for VVF requirements. High Voltage motors can have random wound stator windings, or formed coils, depending on space and weight constraints. The winding wire for the High Voltage motors is double insulated and passes a twisted wire test at 16,000 volts and is rated up to 155 Deg.C. All windings are designed to keep ‘turn to turn’ voltage to a minimum. All winding materials and cables are specially selected to be suitable for use in hydraulic oils.
In general, SME Subsea motors have low loss lamination steel (3 watts/kg), which allows for higher flux densities, and less heat, with less materials and weight.
All motors are oil filled and we recommend hydraulic oils for good lubrication characteristics in preference to electrical oil ( which has better di-electric capabilities, but worse lubrication capabilities).
If motors are going to drive a water pump, SME can design the motor to take the thrust load from the pump and keep the sea water out of the motor with a single or double mechanical seal arrangement.
Small thruster motors can be designed and built for voltage/speed control, which is a relatively simple speed control system and can be built with a thrust bearing incorporated to take the thrust load from the impeller.
To ensure the integrity of the motor housing, SME does not use castings. All components are machined from solid or from extrusions. The external aluminium components are typically 6061 T6 marine grade aluminium and hard anodized to a military specification.
All ball bearings are from well known brands such as SKF, FAG, or NSK. Oil seals are high temperature and typically made from Viton. Mechanical seals are typically Burgmann.
All hardware used on SME Subsea motors is 316SS.
All fixing holes are blind. Oil in and out fittings and the stator pack-fixing bolt, if applicable are sealed with O rings.
The preferred power cable entry system for SME motors is to use an “oily tube” connected to an adaptor, which is part of an oil tight rubber gland that is fixed to the stator frame.
SME do not recommend bringing the power cables through the end-shields of the motor as this creates additional complications when the motors are stripped down during service (because the end-shields cannot be readily removed from the stator). Subsea connectors can be offered as an alternative to the Oily Tube if requested.
SME strongly recommend that the motors are fitted with PT100s fitted in the windings and also to the bearings. The internal motor temperatures are monitored and set up to alarm if the temperatures rise above a safe temperature. SME can also offer additional protection with a water detector. The auxiliary connections for PT100s, can be made through standard high pressure, water tight, plug and sockets as, supplied by “Subconn”, “Impulse”, and “Burton”. These are also fitted to a connection block on the stator, not on the end shield.
All finished motors are pressure tested to ensure they are “oil tight” and suitable for compensated operation down to 4000 metres.
All motors are rated for continuous operation and all prototype motors are full load performance tested at rated voltage and rated frequency to confirm their performance characteristics. All motors can be issued with a “Type Test Certificate” or even full load tested at additional cost, if required.
SME can offer to arrange for hydraulic pumps to be set up and tested on the motors at rated voltage and frequency.
SME can offer to supply Hydraulic Power Units, “complete”, with the addition of customer specified Hydraulic Pump.
SME Subsea motors can be designed and built for all subsea applications, such as ROVs, Trenchers, Ploughs, Submarines and Dredges.
All brands of Subsea motor can be serviced, repaired and tested by SME. In some cases the original motors can be significantly upgraded. If you are having problems with your existing Subsea motor please contact SME – we are ready and able to provide assistance and we are very price competitive.
APPLICATIONS Driven equipment can include: Hydraulic Pumps: For ROV Hydraulic Power Units, Subsea Robotics, Thrusters, etc. Water Pumps: For Jetting Systems, Hull Cleaning, Trenching and Pipe and Cable Laying Equipment, Pipe Pressurisation, Dredging, etc. Propellers/Impellers: For Remotely Operated Vehicle Thrusters, Manned Submarine Thrusters, Mass Flow Excavation, etc. Gearboxes: For Subsea Winches, Cable Tensioners and De-reelers.

Motors are suitable for operation Using variable speed drives and SME can provide advice on variable speed drive operation if requested.
INSTRUMENTATION SME Subsea Motors are available with a range of instrumentation: Bearing and Winding Temperature Monitoring Water Ingress Detection Pressure Transducer Resolvers and Encoders Tachometers
COOLING Motors are generally designed to operate with no additional cooling other than the ambient water temperatures but in some cases external cooling may be required. SME can provide motors with closed loop cooling circuits or motors that are suitable for use with externally fed cooling circuits.
ELECTRICAL CONNECTIONS SME Subsea Motors use an oily tube termination for all power connections as standard. However, appropriately sized and rated Subsea connectors can be used as an alternative, either a Bulkhead Connection on the motor, or as part of a fixed Flying Lead Termination. Instrumentation is generally terminated using a variety of Subsea Connectors. Customers are free to specify their Connectors of choice.
MECHANICAL INTERFACE Motors are design built to suit the application and SME can supply a broad range of interfaces from direct coupled arrangements to the use of separate coupling housings. SHAFTS: Female and Male Spline Shafts, Internal and External Keyed Shafts. FLANGES: NEMA, IEC, SAE, DIN Standards are all available as well as unique requirements. Motors can be provided with Double Ended Arrangements to drive multiple loads.
MOTOR MOUNTING Motors can be provided with various Mounting arrangements including Feet, Flanges, Brackets, or Clamping. In most cases SME can match the mounting interfaces of units being replaced to ensure ease of installation in existing equipment. Motors can be manufactured for Horizontal or Shaft Up or Down installation.
COMPENSATION REQUIREMENTS Motors are built to utilise external compensation. Motors are fitted with oil in and out ports as well as several bleed points to facilitate easy plumbing. Fittings can be provided with BSP, NPT or JIC and other fittings with both straight and tapered threads to provided uniformity on the installation.

SPECIFICATION FOR SUBMERSIBLE AND SUBSEA MOTORS.TYPE OF MOTORStandard Water FilledSubmersible, water tight, and water filled, with double insulated wire and capable of continuous operation at nameplate power under water in a maximum water temperature of 35 Deg.C. without de-rating, and suitable for “Direct on Line” starting. Six lead motors for “Star/Delta” starting are available as an option. Heat Exchanger Water FilledSubmersible, water tight, and water filled, with double insulated wire and capable of continuous operation at nameplate power under water in a maximum water temperature of 55 Deg.C. without de-rating, and suitable for “Direct on Line” starting. Six lead motors for “Star/Delta” starting are available as an option. This motor is recommended for high ambient water temperatures and for extended motor life due to the reduced winding temperatures. Oil Filled.Submersible, water tight, and oil filled, with double insulated wire and capable of continuous operation at nameplate power under water in a maximum water temperature of 30 Deg.C. without de-rating, and suitable for “Direct on Line” starting. This motor is recommended for very cold water where there is a probability that the water (in a water filled motor) might freeze. MOTOR RATINGAll motors are rated for continuous duty (S1) at nominated voltage and frequency. WATER COOLINGCooling water flow rate must exceed 0.5 feet/sec or 0.15 metres/sec. The maximum flow rate must not exceed 10 feet/sec or 2.5 rri/sec. The pH level should be between 6.5 and 8.0. WATER FILLEDThe motors are filled with 90% water and 10% propylene-glycol as standard, but some cold weather markets require 70/30 or even 50/50 ratios to prevent the water from freezing. Clean tap water is the preferred water type. (Oil filled motors are filled with a food grade oil). MATERIALSStandard motors have epoxy painted cast iron ends with a 316 Stainless Steel stator frame and 316 hardware. For aggressive water all external metal components are 316 Stainless Steel. (Duplex, Super Duplex and Ni Al Bronze motors can also be supplied). PRESSURE COMPENSATIONPressure compensation is managed by using a suitably sized Neoprene bellows to allow for expansion of the internal water as it heats up – or – from external pressure due to the depth of submergence. SEALSAll motors are fitted with a mechanical seal on the drive end and a stainless steel slinger to prevent external water and foreign material from entering the motor. The seal faces are Silicon Carbide / Silicon Carbide. Some motors can be supplied with double mechanical seals – on request. BEARINGSHydrodynamic carbon sleeve bearings are fitted at both ends of the motor. They are water lubricated, with a large surface area to DOWN THRUST BEARINGAll the Down-Thrust bearings are Kingsbury style, with hardened and lapped cast stainless steel pivot shoes and a wear resistance carbon/antimony carbon disc. UPTHRUST BEARINGUp-Thrust bearings are carbon, or, cloth and resin based wear material. BALANCINGRotors are balanced to less than 1mm/sec in all planes when measured on No Load. LAMINATION STEELAll motors use low loss cold rolled silicon lamination steel with a core loss of 3 Watts/kg at 50 Hz and 1.5T. WINDING WIREStandard winding wire is PEI2 Copper with a continuous watertight polypropylene covering and nylon overcoat for additional mechanical protection. TestingAll motors are Type Tested and Test Reports can be supplied for individual motors to customer requirements. Temperature rise tests must be conducted while the motor is immersed and subjected to a continuous stream of cooling water – usually as part of a pump test. The temperatures inside the motor, and of the cooling water, are monitored and recorded. WINDINGSAfter the stator leads have been fitted the whole stator is submerged in water and pressurised to 30 psi for 30 minutes and then Hi-Pot tested at 2,500 Volts (for 415V and 460V motors while still at 30-psi pressure. The results are recorded. Please note – this is a “one of” factory test. Future Hi-Pot tests should be done at reduced voltages. COMPLETE MOTORThe winding of the complete motor after filling with water/glycol is “Meggered”, (Insulation Resistance Test), and the resistance at 3000 volts, (for 415V motors), should exceed 1000 M0hm. Please note – this is a “one off factory test. Future “Megger” tests should at 1,000 or 500 Volts. NO LOADThe complete motor is run on No Load and the No Load currents, No Load voltages, and the “Run down time“ are recorded. The vibration levels are also measured at both ends of the motor and in both planes. FULL LOAD TESTAll motors can be Full Load Performance Tested for Efficiency, Power Factor, Speed, and Temperature Rise. All calculations are in accordance with IEC Standards. In addition 4 PTl00s are fitted and monitored inside the motor during testing – one in the proximity of the thrust bearing, one in the centre of the stator pack in a stator slot, and one each on the end winding on the drive end and non drive end. LOCKED ROTOR TESTAll motors can be locked rotor tested to determine the locked rotor current and the locked rotor torque. This test may be done on reduced voltage and a number of points plotted to extrapolate the full load condition. MECHANICAL TESTSThe runout for the shaft and the flange spigot are measured and recorded. The dimensions of the shat, flange spigot, shaft projection, thrust clearance, and shaft deflection, should also measured and recorded.

GENERAL INFORMATION ON SUBMERSIBLE ELECTRIC MOTORS.
Submersible electric motors are generally long and thin and designed to operate in a borehole coupled to a submersible multistage pump. In recent years the motors have been used in a number of different applications. Typical applications are: · Submersible pumps for water supply – drinking water and industrial water. · Booster pumps for high rise buildings. · Mine dewatering. · Dewatering for Civil Engineering Projects. · Irrigation. · Fire fighting and sprinkler systems. · Air conditioning systems. · Offshore oil rigs – sea water lift pumps for re-injection and cooling, ballast pumps, and fire pumps. · Water treatment plants. · Fountains. These motors, with multistage pumps attached, are designed to be lowered into a small diameter borehole to pump ground water. Typical bore holes have 4”, 6”, 8”, 10”, 12” and 14” internal diameters usually this is a steel or plastic pipe which is pushed into a hole after it is drilled to form the well liner or well casing. The motors are actually smaller than their dimensional name implies. The Inch dimension actually refers to the ID of the hole not the motor diameter. The motors need to be smaller than the hole to allow water to pass between the motor and the well liner and into the pump.
There are three different types of submersible motor:- Canned Type Water filled Type Oil filled Type Comparison of Features Type of Motor Type of Winding Rewind-able Size Reliability Acceptable for pumping drinking water Temp Rating of the Winding Ambient Temp of Water being pumped Canned Or Encapsul-ated Normal Enamel Wire – PEI2 No 4” 6” 8” Good Yes 90ºc Max 35 deg.C. Water Filled PVC Covered or PE / nylon Yes 6” 8” 10” 12” 14” 16” 18” 22” 26” Good Yes 90ºc Max 35 deg.C. Oil Filled Normal Enamel wire Yes 4” to 16” Not so Good Probably not 120º Max 35 deg.C. These parameters will vary between different manufactures. Note: Oil filled motors can be filled with a Vegetable oil, which is safe for human consumption, however most water Authorities do not want to take the risk of consumers complaining of oil in their water, which could happen if and when the oil leaks from the motor. Costs vs Reliability Canned type motors are slightly more expensive than oil filled or water filled motors. Oil filled motors in the smaller sizes are less expensive than water filled motors. Canned and water filled motors tend to be more reliable than the oil filled motors, because of the complexity of ensuring that the oil can expand and contract without escaping from the motor. Cooling and Good Water FlowThese motors rely on good water flow past the motor. Water flow velocity must be between 0.5 ft/sec. to 10 ft/sec. (15cm/sec to 300 cm/sec). If the flow is less than this the motors will probably overheat and burn out. Surprisingly if the flow is more than this, motors will also overheat because the high velocity does not allow efficient heat transfer from the motor to the water. These motors are designed for high power outputs in small sizes in comparison with normal air cooled motors. Because water is a very efficient cooling medium, compared with air, the current density in the stator winding is much higher than an air cooled motor. This is acceptable provided the external body of the motor is efficiently cooled be the external water. If there is no external water flow or if the external water ambient temperature is too high the motor will overheat. If the internal water reaches boiling point it will form steam which will force a way out of the motor past the seals. If enough steam escapes the top bearing will run dry and fail, or the winding wire will melt and cause a catastrophic failure in the winding. Oil also a reasonable conductor for heat compared to air but not as good as water.Oil cooled motors are more tolerant to overheating, but in general the oils used in these motors can only operate up to 90ºC before they start to carburize and degenerate – the oil turns black and has a burnt smell when the motor is opened. Oil cooled motors have to be designed to allow the oil to expand as it heats up. Typically the internal oil will expand by at least 10% and the bellows have to be able to expand to accommodate this as the motor heats up and contract again when the motor cools down. Water does not expand very much as it heats up so it is easier to design the bellows to allow for the expansion and contraction. Internal water will probably escape from the motor and / or external water will enter the motor eventually, however this should not be a problem for the water cooled motor unless sand or foreign matter manages to enter the motor, as this will probably lead to increased wear on the bearings and eventual mechanical failure.

If the current increases the motor will trip which will alert the operator to the fact that something has changed). Current Underload – 10% below current during commissioning. This may need to be increased depending on how the motor is operated. (We believe that the operator should be alerted when the load changes). Over Voltage – 10%. Under Voltage – 10%. Voltage Unbalance – 2%. SME recommend that ALL water filled motors should have at least one PT100 installed in the motor. From experience we know that the hottest spot in most water filled motors is in the end winding on the Drive End. If a PT100 is installed and connected to a display/protection unit the operator can monitor the actual temperature in the motor. There are a lot of variables that effect the winding temperature, such as current unbalance, load, ambient water temperature, etc. and it is impossible to predict exactly what the winding temperature will be in operation. Provided the winding temperature is below 80 deg. C. the operator can be confident that the motor will operate reliably even if there are problems with the site conditions. aw

SME Specification For Submersible Motors STANDARD WATER FILLED Submersible, water tight, and water filled, with double insulated wire and capable of continuous operation at nameplate power under water in a maximum water temperature of 35 Deg.C. without de-rating, and suitable for “Direct on Line” starting. Six lead motors for “Star/Delta” starting are available as an option. HEAT EXCHANGER WATER FILLED Submersible, water tight, and water filled, with double insulated wire and capable of continuous operation at nameplate power under water in a maximum water temperature of 55 Deg.C. without de-rating, and suitable for “Direct on Line” starting. Six lead motors for “Star/Delta” starting are available as an option. This motor is recommended for high ambient water temperatures and for extended motor life due to the reduced winding temperatures. OIL FILLED Submersible, water tight, and oil filled, with double insulated wire and capable of continuous operation at nameplate power under water in a maximum water temperature of 30 Deg.C. without de-rating, and suitable for “Direct on Line” starting. This motor is recommended for very cold water where there is a probability that the water (in a water filled motor) might freeze. MOTOR RATING All motors are rated for continuous duty (S1) at nominated voltage and frequency. WATER COOLING Cooling water flow rate must exceed 0.5 feet/sec or 0.15 metres/sec. The maximum flow rate must not exceed 10 feet/sec or 2.5 rri/sec. The pH level should be between 6.5 and 8.0. WATER FILLED The motors are filled with 90% water and 10% propylene-glycol as standard, but some cold weather markets require 70/30 or even 50/50 ratios to prevent the water from freezing. Clean tap water is the preferred water type. (Oil filled motors are filled with a food grade oil). MATERIALS Standard motors have epoxy painted cast iron ends with a 316 Stainless Steel stator frame and 316 hardware. For aggressive water all external metal components are 316 Stainless Steel. (Duplex, Super Duplex and Ni Al Bronze motors can also be supplied). PRESSURE COMPENSATION Pressure compensation is managed by using a suitably sized Neoprene bellows to allow for expansion of the internal water as it heats up – or – from external pressure due to the depth of submergence. SEALS All motors are fitted with a mechanical seal on the drive end and a stainless steel slinger to prevent external water and foreign material from entering the motor. The seal faces are Silicon Carbide / Silicon Carbide. Some motors can be supplied with double mechanical seals – on request. BEARINGS Hydrodynamic carbon sleeve bearings are fitted at both ends of the motor. They are water lubricated, with a large surface area to DOWN THRUST BEARING All the Down-Thrust bearings are Kingsbury style, with hardened and lapped cast stainless steel pivot shoes and a wear resistance carbon/antimony carbon disc. UPTHRUST BEARING Up-Thrust bearings are carbon, or, cloth and resin based wear material. BALANCING Rotors are balanced to less than 1mm/sec in all planes when measured on No Load. LAMINATION STEEL All motors use low loss cold rolled silicon lamination steel with a core loss of 3 Watts/kg at 50 Hz and 1.5T. WINDING WIRE Standard winding wire is PEI2 Copper with a continuous watertight polypropylene covering and nylon overcoat for additional mechanical protection.
Submersible Subsea MotorTesting All motors are Type Tested and Test Reports can be supplied for individual motors to customer requirements. Temperature rise tests must be conducted while the motor is immersed and subjected to a continuous stream of cooling water – usually as part of a pump test. The temperatures inside the motor, and of the cooling water, are monitored and recorded. WINDINGS After the stator leads have been fitted the whole stator is submerged in water and pressurised to 30 psi for 30 minutes and then Hi-Pot tested at 2,500 Volts (for 415V and 460V motors while still at 30-psi pressure. The results are recorded. Please note – this is a “one of” factory test. Future Hi-Pot tests should be done at reduced voltages. COMPLETE MOTOR The winding of the complete motor after filling with water/glycol is “Meggered”, (Insulation Resistance Test), and the resistance at 3000 volts, (for 415V motors), should exceed 1000 M0hm. Please note – this is a “one off factory test. Future “Megger” tests should at 1,000 or 500 Volts. NO LOAD The complete motor is run on No Load and the No Load currents, No Load voltages, and the “Run down time“ are recorded. The vibration levels are also measured at both ends of the motor and in both planes. FULL LOAD TEST All motors can be Full Load Performance Tested for Efficiency, Power Factor, Speed, and Temperature Rise. All calculations are in accordance with IEC Standards. In addition 4 PTl00s are fitted and monitored inside the motor during testing – one in the proximity of the thrust bearing, one in the centre of the stator pack in a stator slot, and one each on the end winding on the drive end and non drive end. LOCKED ROTOR TEST All motors can be locked rotor tested to determine the locked rotor current and the locked rotor torque. This test may be done on reduced voltage and a number of points plotted to extrapolate the full load condition. MECHANICAL TESTS The runout for the shaft and the flange spigot are measured and recorded. The dimensions of the shat, flange spigot, shaft projection, thrust clearance, and shaft deflection, should also measured and recorded.

Wet and Dry Pit Motors SME – WD Series Motors – for Open Well or Sump Applications Submerged or not Submerged, Cast Iron, Steel, or Stainless Steel Construction SME has many years experience in the manufacture of submersible motors and the WD series of motors have been designed for the toughest jobs to ensure reliability and a long service life. When conditions are extreme and performance is critical these motors deliver the quality and durability required. WD motors are designed for continuous operation in sludge, effluent, slurry, and other liquids – to a submergence of 10 metres, in an open well, a river bank, a tailings pond, or a sump. The motors are air filled, with a separate oil filled seal chamber to ensure robust sealing of the drive shaft. The WD Series motors can also be supplied with a large range of sealing options to ensure the motor is suitable for the most extreme conditions from a combination of lip seals, and/or mechanical seals, to complex cartridge seal arrangements. If the motors are going to be continuously submerged they will rely on the liquid they are submerged in for cooling. If they are not going to be submerged continuously – or only intermittently — they are designed with a water jacket for cooling and water is usually bled from the pump through the water jacket. These IP68 motors have been used in both vertical and horizontal applications driving a diverse range of pumps in many unique applications. The Motors can be supplied with an extensive array of flange and shaft dimensions to ensure the motors can be matched to a large range of different pumps. The motors can also be supplied with standard IEC and NEMA flange and shaft dimensions. The motors are very robust and designed to take the physical abuse on a typical mine site. They can tolerate overloads, and a lack of cooling. They can maintain full load operation for 15 minutes with no external cooling. These motors offer a robust alternative to other units that suffer from shorter operating lives – with no changes to the existing Wet end performance. These motors are fitted with moisture detection probes and PT100, or themiistor, thermal protection — as standard – and provided these are properly connected and set to give advance warning of problems these motors will give many years of reliable service in extreme applications.
