Motor

The invention provides a motor. The motor includes a casing and two end covers disposed on the rear end portion and the front end portion of the casing respectively. According to the technical solution of the present invention, conductive holes are disposed on the front and rear end portions of the casing of the motor. After the front and rear end portions of the casing are sleeved with the end covers, conductive members are inserted into the conductive holes on both ends of the casing and penetrate through the casing and the end covers. The walls of the conductive holes on the casing and thewalls of the conductive holes on the end covers are in contact with the conductive members such that the casing is in electrical connection to the two end covers. A grounding device can be disposed onthe casing and the end covers to achieve the insulation protection of the casing and the end covers. During the use of the motor, even if an electric leakage occurs and the insulation protection on the casing or the end covers is damaged, the leakage current can be released to the ground through the grounding device to prevent an electric shock caused by a human touch.
