Abstract

PURPOSE:To improve the productivity of a rotor by positioning a magnet material not magnetized to a rotor housing and filling plastic. CONSTITUTION:The annular magnet material 2b not magnetized, which is concentrical to the rotor housing 1 in metal, the fringe thereof has a rim 1a, and can has a clearance between the magnet material and the rim 1a, is positioned in molding cavities K1-K4. The plastic is injected simultaneously to the central section of the rotor housing 1 and the magnet material 2b not magnetized and the clearance between the magnet not magentized and the rim, and a rotor spindle 3 and a filled section 4 are formed. The magnet 2b not magnetized is magnetized, and the rotor is obtained using the material as a magnet. According to this method, the rotor spindle to which a capstan, etc. are mounted can be molded when assembled with the rotor housing and the magnet while the filled section protecting the magnet can be shaped in the outer circumferential space of the magnet.
