Working Principle
FCMA Frequency controlled Automatic Slip Regulator are based on frequency dependent resistance design which provide a constant low starting current with automatically reducing resistance in congruence with motor speed to provide constant torque characteristics & accelerate the motor Frequency Slip Regulator / Frequency Rotor Controller accelerates driven equipment from stand still to full speed smoothly without any jerks. The FCMA Rotor Starter & Slip Regulator is connected to the Rotor Terminals of the motor, so that the starting current is limited to a low value with a required starting torque. As the motor speed increases the resistance of FCMA reduces Steeplesly to keep the current & torque constant so that the load is accelerated.
