Abstract

A motor comprises a stationary portion, a rotor, and a magnetic-conductive balance plate. The stationary portion has a stator assembly provided with at least one coil and at least two pole faces. Each of the pole faces has a strong pole portion and a weak pole portion. The rotor has an annular magnet aligned with the pole faces of the stator assembly. The magnetic-conductive balance plate mounted on the stationary portion, and has at least two magnetic-conductive faces which are aligned with the weak pole portions of the pole faces and faced the annular magnet of the rotor. In operation, the annular magnet of the rotor can be driven by the alternative magnetic field generating from the strong pole portions of the pole faces, and permanently attracts the magnetic-conductive faces of the magnetic-conductive balance plate so as to maintain the rotational balance of the rotor.
