What is FCMA Soft Starter?

• The harmonic free, rugged magnetic soft starter for motor starting.
• FCMA is an acronym for flux compensated magnetic amplifier which is basically a modulated inductive impedance.
• When connected in series with the motor the FCMA reduces the starting current to a low value.
• The impedance of FCMA decreases with increasing motor speed by flux compensation thus incrementing the motor voltage without sleep to keep the current constant till motor reaches 90% speed (pullout torque).
• The motor voltage increment is typically from 50% at start to 95% at full speed gradually.
• The FCMA is further bypassed by a suitable contactor so that the motor runs at line voltage.
