S and SS THREE-PHASE INDUCTION ELECTRIC MOTORS FOR SUBMERSIBLE PUMPS DRIVE
The S and SS type submersible motors are intended for driving the submersible pumps mounted in deep wells and pumping clean water.
The S type motors may be fitted in wells of minimum 200 mm (8 inch) dia, while the ASS type ones, in wells of minimum 250 mm (10 inch) dia. The motor-pump units operate only in vertical position, namely the motor beneath, and the pump on top of it, the connection being achieved by means of a bushing.
The motors are available with one or two (in the case of the star-delta starting) supply cables 3 m long. On demand, motors may be available with other cable lengths as well (max. 100 m). The motors are usually designed for 380 V supply voltage and 50 Hz frequemcy. On demand, motors may be designed for other supply voltages, as well as for 60 Hz frequency.
