Description
This is a three-phase induction motor with a squirrel-cage rotor and a mechanical shaft seal, and the winding can be rewound. The housing is made of cast iron, bronze or stainless steel depending on the medium, and the installation is vertical or horizontal. In the MCT cooling technology, an optimized impeller on the lower end of the rotor shaft pumps drinking water through the motor. Therefore no maintenance is needed, and the motor works in a medium up to 75 °C without derating and without oil cooling, which could contaminate the water. The MPT technology gives up to 100 % more power at a given borehole diameter, so the borehole can be made narrower. The version with internal permanent magnets (IPM) works together with a frequency converter and keeps high efficiency at partial loads; according to the manufacturer, an IPM motor in the frame of a 45 kW induction motor develops 100 kW. The motors are used in municipal and industrial water intakes, in irrigation, in the mining industry and in seawater systems.
How to choose
The selection starts with the power up to 700 kW and the borehole diameter, because the MPT technology increases power in the same diameter. The housing material of cast iron, bronze or stainless steel is chosen according to the composition of the pumped water. If efficiency at partial loads is important, the IPM version paired with a frequency converter is considered. For voltages above 1 000 V there is a high-voltage version up to 14 kV, which is listed as a separate item.

FAQ
Up to what power are the SM series low-voltage motors made?
Up to 700 kW for voltages up to 1 000 V. The speed reaches 3 600 rpm.
Is oil cooling needed for the SM motor?
No. The motor is filled with water and cooled by it using the MCT technology, and no maintenance is needed.
Up to what ambient temperature does SM work without power derating?
Up to 75 °C without derating.
What does the MPT technology give in a borehole motor?
Up to 100 % more power at a given borehole diameter, so a narrower borehole can be used.
What should be taken if a voltage above 1 000 V is needed?
The high-voltage version of the SM series goes up to 14 kV and is listed in the catalogue as a separate item.
