Abstract

PURPOSE: To obtain a rotor that working at high accuracy is easy, inertia is little and does not race, by pressing a rotor magnet, to which outer surface revolution preventive portions are mounted, into a metal mold, and by integrally molding a rotor core portion with high molecular materials.
CONSTITUTION: A rotor magnet 4 is set to an upper metal mold 1, to which a rotor core-shaped concave portion 3 with a gate 2 and a concave portion 5 for housing the rotor magnet are mounted, and a lower metal mold 6, to which a rotor core-shaped concave portion 7, a rotor metal-shaped concave portion 8, etc. are installed, softened resin is poured from the gate 2 and rotor core portions 11, 12, a rotor metal portion 13 and a rotor connecting portion 14 are integrally molded. The rotor magnet 4 is provided with a through hole 4b at the center portion while two circular concave portion-shaped revolution preventive portions 4a are mounted to an end surface at one side in the thickness direction, and racing is obviated by pouring resin to the revolution preventive portions 4a.
