Manufacturer IP20 AC380V 630KW Durable Motor Soft Starter Control Panel Soft Starter Cabinet for water pump

The online soft starter cabinet uses three-phase parallel thyristors as voltage regulators, which are connected between the power supply and the motor stator. Such a circuit is a three-phase fully controlled bridge rectifier circuit. When using a soft starter to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully turned on, and the motor works on the mechanical characteristics of the rated voltage to achieve smooth start, reduce the starting current, and avoid starting overcurrent tripping. The online soft starter cabinet also provides a soft stop function. The soft stop is the opposite of the soft start process. The voltage gradually decreases and the speed drops to zero to avoid torque impact caused by free stop.
