Soft starters are …

NettetIt occurs due to the high winding current during its startup. The soft starter allows a very small amount of starting current which prevents the overheating of the motor. The soft starter as compared to a DOL starter improves the lifetime of the motor. It is due to the smooth operation & absence of electrical & mechanical stress on the motor.

NettetThe soft starter uses this technique to start an induction motor. Multispeed Starter ; the motor is designed to have multiple preselected speeds that is achieved through pole (winding) configuration. Gradual increases of speed reduce the inrush current.
