Diagnosis and maintenance: This is a symptom of phase loss of the motor. Now the controller is mostly intelligent, and it will jitter due to zero phase start. This may be caused by the damage of the motor hall, and there is a possibility that there is a problem in a phase line circuit inside the controller. After carefully checking whether there is any problem with the connection cable, if both the Hall and the connection cable are detected normally, then the internal components of the controller have failed, please replace the controller!
