Slip Ring Motors

Compact design makes them very easy to handle, at the same time requiring virtually no maintenance.

Once the motor is accelerated, the resistance is cut out of the rotor resistance and the rotor slip rings are short-circuited. This results in the motor operating at rated speed , similar to the case of a squirrel cage induction motor.

The rotating field travels at synchronous speed, cutting the wound rotor winding and thereby induces voltages in these winding. When you start the motor all the resistance of the rotor resistance starters inserted into the circuit. The increase in resistance in the circuit increases the impedance. This enables maximum interaction between the two fields and highly strong starting torque.

When three-phase power is applied to the stator winding, a rotating magnetic field is formed. This field travels around the inside of the stator core, as in the case of a squirrel case induction motor.

Our Slip ring motors are made out of the finest quality material and are designed after extensive testing in our state-of-the-art R & D facility. Capable of working under varied RPM, our range of Slip ring motors are already being extensively used. The rotor, which is similar to squirrel cage induction motor, consists of a cylindrical core made up of lamination. Slots in this lamination core hold the coils for three single phase winding, which are placed at 120 electrical degrees apart. The three single-phase rotor windings are connection to slip rings which are mounted or to the rotor shaft. Extension leads from carbon brushes are connected to an external rotor resistance starter.
