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 ?lled 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 ?ange 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 ?ange 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 ?tted 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. Our ?exible design capabilities mean we can manufacture Water Cooled Motors to suit most applications. Our range of motors include Flexible Interface Dimensions to suit all requirements and provide the possibility of “Drop In‘’ replacement motors.

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.

TESTING
SME‘s West Australian facility, located in Perth, provides for an extensive testing regime for repaired and overhauled motors. SME can full load test motors on our dynamometers and can also offer performance testing of complete pump/motor units in our purpose built test tank – at the specified voltage and frequency up to 6600 volts.
SME can guarantee motors that have been serviced and repaired are fit for purpose before dispatch, providing customers with complete confidence in the work prior to re-installation. All motors that re rewound by SME are subject to an immersion pressure test which is conducted in our pressure test vessel to ensure the integrity of the windings prior to assembly and load testing. Our commitment to a strict testing regime protects our clients from the risks of downtime caused by unexpected failure.
