摘要： An inner-rotor-type motor includes a housing, a stator, a rotor, a permanent magnet and a cover plate. The housing has a compartment. The stator is received in the compartment. There is an assembling hole arranged at the axial center of the stator and passing through the stator from the top to the bottom thereof. The rotor has a shaft with one end thereof rotatably extending through the assembling hole, with a bearing being mounted around the shaft. The permanent magnet is fixed to an outer periphery of the shaft and beside the bearing, with the permanent magnet facing the stator. The cover plate is arranged between the permanent magnet and the bearing. Consequently, impurities are prevented from entering an undesired interstice between the bearing and the shaft or from entering the inside of the bearing, such that smooth rotation of the rotor is provided and such that life of the inner-rotor-type motor is extended.
