Abstract
A film capacitor for a deep-well pump motor is an annular one. The external diameter of the film capacitor is smaller than the external diameter of a stator chamber of the deep-well pump motor. The internal diameter of the film capacitor is larger than the external diameter of a rotor chamber of the deep-well pump motor. The height of the film capacitor matches the distance between a lower sealing cover and a stator of the deep-well pump motor. The film capacitor which is designed into an annular shape can be arranged inside the motor the inner side of which is sealed. Thus, the capacitor is significantly protected from being invaded by moisture. The service lifetime of the film capacitor can be prolonged. The repair rate of a deep-well pump can be lowered. As proved by tests, the service lifetime of the film capacitor can be prolonged by more than 30%.
