This application provides a motor, including a housing, a shaft bearing, a motor shaft, a first sealing member, a conductive post, a conductive bearing, a second sealing member, and a conductive connecting member. The motor shaft is rotatably installed on the housing through the shaft bearing. A part of the motor shaft is located inside the housing, and the motor shaft has a cavity. The first sealing member, the conductive bearing, the second sealing member, the conductive post, and the conductive connecting member are all located inside the housing. The first sealing member, the conductive bearing, and the second sealing member are located inside the cavity. The conductive bearing is located between the first sealing member and the second sealing member, and the first sealing member and the second sealing member seal the conductive bearing in the cavity. An outer ring of the conductive bearing is fixedly connected to a cavity wall of the cavity, and an inner ring of the conductive bearing is fixedly connected to an outer circumferential surface of the conductive post. The conductive connecting member is connected to one end, facing away from the first sealing member, of the conductive post and is electrically connected to the housing. According to the solutions of this application, the shaft bearing can be prevented from electric corrosion, and reliability of the shaft bearing can be ensured.
