- Flux Compensated Magnetic Amplifier soft starters are step less reduced Voltage starters which ensure a constant low starting current with incremental voltage and torque to the motor to achieve smooth acceleration of the drive.
- The Soft Starter is connected in series with the motor either on the line side or neutral side and thus controls the starting current and starting torque.
- As the motor speed increases the FCMA impedance decreases due to counter emf feedback to achieve incremental voltage and torque for the motor while keeping the current constant.
- The voltage across the motor increases smoothly from the starting value(50-60%) to run value(94-98%) with motor speed.
- A built-in bypass contactor closes to ensure full voltage running of the motor.
- Bypass contactor operation can be time,Current or speed based.
