Soft start and soft stop overview

A soft starter is an electronic motor control device for the soft start and stop of three-phase induction motors. The motor voltage is adjusted with a phase control by a ramp function. The supply frequency of the motor remains identical to the mains frequency. With soft starting, the initial voltage (= starting torque) and the voltage rise (= acceleration) are adjustable. During soft stop, the voltage is reduced with a ramp function.

Applications:
* Speed control e.g. of fans and blowers 
* Motor starting – conservation of resources
