A motor includes a fixed portion, a rotor, and a balancing plate. The fixed portion includes a stator having at least one winding and a plurality of pole faces. The rotor includes an annular magnet facing the pole faces of the stator and a shaft rotatably extending through the fixed portion. The balancing plate is mounted on the fixed portion and includes a connecting portion and at least two magnetically conductive faces that are integrally formed with the connecting portion as a single member and that face at least one face of the annular magnet. The at least two magnetically conductive faces are supported and connected by the connecting portion of the balancing plate. The at least two magnetically conductive faces and the annular magnet provide a magnetically attracting balancing effect for the rotor.
