Cage asynchronous motors are inductive loads in which the current in the stator coil windings lags behind the voltage. If the working voltage of the motor is constant, when the load is light, the power factor is low, and when it is under heavy load, the power factor is high. The soft starter can achieve the purpose of light load and energy saving by reducing the motor terminal voltage, reducing the power factor, reducing the copper consumption and iron consumption of the motor at light load; when the load is heavy, the motor terminal voltage is increased to ensure the normal operation of the motor. .
