FCMA Starters

(Flux Compensated Magnetic Amplifier) Electrical Soft Starter is step-less voltage-reducing starter.

FCMA

(Flux Compensated Magnetic Amplifier) Electrical Soft Starter are step-less voltage-reducing starters. It ensures a constant low starting current with incremental voltage and torque to the motor, to achieve a continuous and smooth acceleration of the drive.

FCMA soft starters are air-core-based series reactors, providing a complete starting solution for motor applications involving pumps, blowers, fans or compressors.

FCMA Principle

FCMA Soft starters work on the principle of impedance control by superimposing two-phase opposed alternating fluxes on a common magnetic core. Controlled impedance, when connected in series with the motor, provides a constant current incremental voltage, resulting in incremental torque as the motor speed increases.

FCMA soft starters control the motor's torque and can be limited to 150 per cent of full load torque. It also controls the amplitude of motor current without distorting the current waveform. This leads to zero harmonics
