A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.

2) Base on the motor power, current and load characteristic to choose the soft starter. Generally, the soft starter capacity slightly larger than the motor operation current capacity, and increase a step power for some heavy loads, such as: crusher, ball mill, hoist, long belts, mixers, fans, etc.

Soft Starter with Motor Protection 100A STO100

A soft starter is an electronic motor controller used on three phase medium voltage squirrel cage induction motors. During motor starting, the soft starter controls the voltage or current supplied to the motor. Motor start performance is optimized by reducing the total start current while optimizing the torque produced by the motor.

Soft Start Vs Vfd For Ball Mill

A soft starter is any device which controls the acceleration of an electric motor by means of controlling the applied voltage. An Induction motor has the ability to self start owing to the interaction between the rotating magnetic field flux and the rotor winding flux, causing a high rotor current as torque is increased. As a result the stator draws high current and by the time the motor ...
