FCMA Soft Statrer

Low starting current with FCMA Starter


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. As the motor speed increases, the controller impedance decreases due to counter emf feed back to achieve constant incremental voltage torque for motor. This achieves very soft and smooth starting of load to Crusher, Compressor, Pumps, Centrifugal fan etc.This also helps in optimizing the power source of transformer or generator capacity. Optimized power system also gives savings in capital, cost savings and revenue expenditure due to higher efficiency.

FCMA SOFT STARTER Application for Soft Starting of Motors

While line contactor closes & motor starts at low current fcma SOFTSTART module controls starting current and accelerates motor to full speed. Keeping current constant motor voltage increases from 50% to 95%. Running contactor closes in normal load condition.Attenuated sinusoidal wave form to motor reduces stator magnetic field resulting in stress free rotor and elimination of unwanted starting torque The fcma SOFTSTART module will improve the energy consumption during starting as well as running of fixed speed of motor. The maximum demand shall be reduced to 67% and running energy savings shall be achieved up to 22%.FCMA SOFT STARTER controls the active and reactive component switching & currents and delivers a harmonics free, non resonating system performance effective up to 1.5 x motor full load current it balance KVA and power quality consumption by monitoring system parameters and also help to maintain the PF during starting and running of the motor.
