摘要:A miniature electric motor has a stator mounted within a casing and a rotorprovided so as to face the stator. The rotor includes a rotary shaft rotatably supportedto the casing, a rotor body into which the rotary shaft is inserted, the rotor body beingmade of plastic, and a magnetic layer formed on an outer circumferential surface of therotary body and made of rare earth plastic magnetic material. Accordingly, it is possibleto obtain a high torque even with a small amount of rare earth plastic magnet and toavoid separation or cracks of the magnetic layer.
