Working Principle

FCMA Slip ring Starter & Slip Regulator are based on frequency dependent resistance design which provide a constant low starting current with automatically reducing resistance instep with motor speed to provide constant torque characteristics & accelerate the motor FSR/FRC accelerates driven equipment from stand still to full speed smoothly without any jerks. The FCMA Slipring Starter & Slip Regulator 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. As the motor speed increases the resistance of FCMA reduces sleeplessly to keep the current & torque constant so that the load is accelerated.
