Answer Posted / electrical work
Soft starter is used to start motor smoothly by limiting current for that used thyristors to control its voltage. Its change voltage to acquire smoothness of current and torque. Selection of soft starter depend on number of starting, application and motor power. once motor gets its speed, soft starter bypass motor to contactor and monitors the motor current current. When stop is required again soft starter take controlling of motor and stop motor. Both acceleration and deceleration can be set by soft starter. It used where soft stars is required and then motor is running in full speed.
VSD is used V/F controlling method and it gives soft start and current and controlling is done by changing drive output frequency. VSD is used where Variable speed required.
