Study on the Safety Design Method of Ultrasonic Cleaning for the Motor Winding

Based on the problem that the ultrasonic cleaning can destroy the insulating layer of the motor winding and affect the motor safety, the destructive effect mechanism is analyzed, designed a enameled wire-based destructive experiment method, and finally realized the selection of cleaning power and time. It was indicated by the motor experiments that the cleaning parameters selected in this way didn´t destroy the insulating layer of the motor winding, and was an excellent method to ensure the safety and reliability of the designed ultrasonic cleaning method.
