      Flexible External Dimensions to suit all applications.

       Dimensions to allow drop in replacement for existing units.

       Anodised aluminium, or, 316 stainless steel.

       Power drive to load using an output shaft with a standard coupling, or, close coupled, etc.

       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 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, like trenching.

If weight is important SME can design the motor for minimum weight by utilising an aluminium construction and a hollow motor shaft, etc., while still ensuring the motor is generously rated for full load operation. 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 4160 Volts with 50Hz or 60Hz frequencies, or for VVVF requirements. High Voltage motors can have random 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, etc. are specially selected to be suitable for use in hydraulic oil.

In general the SME SUBSEA motors have low loss lamination steel (3 Watts/kg), which allows for higher flux densities, and less heat, with less material 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.

Thruster motors can be designed and built for voltage/speed control, which is a relatively simple speed control system, and they can also 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 anodised 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 except the "oil in" and "oil out" fittings and the stator pack fixing bolt, if applicable.

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 which is fixed to the stator frame. SME do not recommend bringing the power cables through the endshields of the motor because this creates additional complications when the motors are stripped down during service, because the endshields 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 supplied with PT100s fitted in the windings and also in the bearings and that the internal motor temperatures are monitored and set up to alarm if the temperatures rise above the "norm". SME can also offer additional protection with a water detector, etc. The auxiliary connections for PT100s, etc. 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 endshield.

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 also 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, ROV HPU, complete with the addition of a customer specified Hydraulic Pump. Also motor-pump sets for both hydraulic and water jetting applications.

SME is a fully quality assured company to ISO 9001.2000 for "Design, development, manufacture, and testing of submersible electric motors and electric motors for remotely operated vehicles".

SME Subsea motors can be designed and built for all subsea applications, such as ROVs, Trenchers, Ploughs, Submarines, Dredges, etc.

All makes 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 motors please contact SME - we are keen to help and we are very price competitive.

At SME we are continually working on improving 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.

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/SME 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/SME 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 /SME 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/SME 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.

6.6Kv Motors Available.

We have manufactured many 6.6kV motors, mainly Submersible Pump Motors for various Mining, and Offshore applications.  Usually we supply to Pump Manufacturers who fit these motors to their pumps.  We can offer the following motors, subject to agreed technical drawings:

SME ROV22-4 300kW 4 Pole SS316 Construction 6600/3/60 Subsea Motor to drive Hydraulic Pump.

SME ROV18-4 300kW 4 Pole SS316 Construction 4100V Subsea Motor to drive Hydraulic Pump.

SME ROV22-4 300kW 4 Pole SS316 Construction 4500/3/60 Subsea Motor to drive Hydraulic Pump.

The method of construction changes at 4100V from Random Wound to Formed Coils so there is a jump from 4100V to the 4500V motor.  The 4500V motor is constructed very similarly to the 6600V Motor.

Silvercrest will bespoke manufacture virtually any shape and size of submersible motor and submersible pump required for subsea operations.  We can offer a wide range of HPU and motor-pump sets complete, subject to any modifications, and changes you may require. For example:
