Controlgears of PCTE series on the base of sub synchronous cascade (SSC) for control over slip ring induction motors

Capacity of drive motor – 500 … 1000 kW

Motor start from zero to minimal value of regulation zone is realized by means of introduction of inductive rheostat in the rotor circuit with following transfer into regulation mode.

Speed regulation range - 50 – 100% of rated speed

Functionality:

Continual operation with steady speed within limits of regulation range mentioned above

Stabilization of set speed

Regenerative braking of the motor within limits of regulation range
