PURPOSE:To adapt a motor for a mass production and to improve the dimensional accuracy by integrally molding a rotor magnet and an index magnet with a magnet of resin binding. CONSTITUTION:A rotor magnet unit 31 and an index magnet unit 32 are composed of a magnet material and magnet powder, and integrally molded as a magnet of resin binding. The inner periphery of the unit 31 is magnetized in a plurality of poles, and the unit 32 is magnetized in a sole pole or N- and S- poles. |
