Abstract

PURPOSE:To efficiently manufacture a rotor by positioning a ring-shaped magnet material with respect to a rotor housing, injection molding a rotor spindle of the prescribed shape to integrate the three, and the magnetizing them to a magnetic material. CONSTITUTION:A metallic rotor housing 1 is contained in a downward direction in a cavity k1 of a lower mold K, an unmagnetized ring-shaped magnet material 2b is concentrically contained with the rim 1a of the rotor housing, plastic is injected into cavities k2, h1, h2 formed by the upper and lower molds H and K, and a rotor spindle 3 which is integral with the inner peripheral surface 2a of the magnetic material 2a and is interposed from both sides at the peripheral edge of the window hole 1b of the rotor housing 1 is formed. After it is released from the mold, the unmagnetized magnet material 2b is magnetized to form a magnet 2, and the coupling between the magnet 2 and the rotor housing 1 is strengthened by the magnetic force.
