fcma SOFTSTART is an indigenous flux compensated technology which is harmonic free rugged magnetic soft start for motor starting. Flux compensation is a system where two sinusoid fluxes are imposed on a core leading to a net sinusoidal flux which controls the impedance of the winding when connected in series with the motor the fcma SOFTSTART module reduces the starting current to a low value. The impedance of fcma SOFTSTART module decreases with increasing motor speed by flux compensation thereby increasing the motor voltage with out lag to keep the current constant till motor reaches pullout torque (90% speed). The motor voltage increment shall be from 50% at start to 95% at full speed gradually. The fcma SOFTSTART module is further bypassed by a proper contactor so that the motor runs at line voltage.
LT & HT harmonics free FCMA Soft starters are designed, manufactured in line with relevant clauses of IEC/ IS standards the applicable standards are per IEC 60289/ 60076-6 for reducing motor starting current. Our Soft Starter is step less start works on a ‘dynamic’ impedance” principle which ensures a constant low starting current, incremental voltage and torque to the motor to get smooth start.
