Abstract
A motor includes a housing, a stator and a rotor. The stator is received in the housing. The rotor includes a shaft and a permanent magnet. The shaft is rotatably coupled to the housing, and one end of the shaft extends out of the housing through a shaft hole. A gap is formed between the shaft and the shaft hole. The permanent magnet is coupled with the shaft and spaced from the stator. A sealing member is arranged on the housing and surrounds the shaft hole. The sealing member includes a blocking portion abutting with a predetermined part of the rotor outside the housing. The blocking portion seals the gap. As such, dustproof and damp-proof functions of the motor are improved.
