The working principle of the soft starter is to gradually increase the voltage of the motor by controlling it, thus achieving a smooth start. Specifically, the soft starter will gradually increase the voltage of the motor according to the preset starting curve during the starting process, so that the motor speed will gradually rise. During the starting process, the soft starter will also monitor the running state of the motor, such as current, speed, etc., and adjust the speed and amplitude of the voltage rise according to the actual situation to ensure the smooth and reliable starting process.
In addition, the soft starter also has a variety of protection functions, such as over current protection, overload protection, lack of phase protection, etc., which can effectively protect the safety of the motor and equipment。
