A soft starter is actually an electronic motor
starter.Instead of using a star delta or a auto transformer
or rotor resistant starter where with the aid of cont actors
and the devices the starting current is reduced to prevent
damage to the motors the machines driven by them or prevent
interruption to the power supply.
The soft starer does the same job but with the advantage of
you being able to preset the starting time and the starting
current consumption.You will be able to determine how much
torque can be given for the starting, but once the starting
is done the soft starter is excluded from the circuit WITH
THE HELP OF A BYPASS CONTACTOR but sometimes maintained just
for monitoring.
