ROTOR CONTROLLER / ROTOR STARTER
-ASR & RC FCMA TYPE

Working Principale Of Rotor Controller

  • Slip dependent Rotor Resistance Starter / Controller are designed with lossy core & based on Rotor frequency dependant resistance design.
  • FCMA Slip ring Starter & Slip Regulator are based on dependent resistance design which provide a constant low starting current ,with automatically reducing resistance in-stepwise with motor speed to provide constant torque acceleration of the motor through ASR/RC accelerates driven equipment from stand still to full RPM smoothly without any jerks.
  • The FCMA base Automatic Slipring Starter-(ASR) & Slip Regulator/Controller (RC) are connected to the Rotor Terminals of the motor, so that the starting current is limited to a low value with a required starting torque.
  • Motor acceleration is smooth, step less and jerk less, as resistance reduction is step less and automatic.
  • As the motor speed increases the resistance of FCMA base ASR & RC reduces sleep to keep the constant current & torque so that the load is accelerated.
  • After achieving to full speed, Rotor Starter will bypass by built in contactor and during running motor will be acting as Squirrel cage induction motor.
