The first question is: what is a soft starter? Simply put, a soft starter is an electronic device which controls the acceleration of an electric motor, in order to greatly reduce the starting current and associated side-effects of direct motor starting.
Most electronic soft starters work by using internal circuitry to regulate the voltage supplied to the motor. By gradually applying more voltage, the motor starts slowly and gracefully and draws much less current while starting (2-3 times the normal running current instead of 7-10 times for a directly started motor). The starting time is often adjustable by the operator. In addition, many soft starters also include a soft stopping feature – the reverse of soft starting.
There’s a number of applications where an electronic soft starter can be very useful:
