UNSATURATED POLYESTER RESIN COMPOSITION, GRANULAR BODY OF UNSATURATED POLYESTER RESIN COMPOSITION, AND ELECTRIC MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a rotor including a resin sealing body having an excellent molding quality by constituting an armature by burying an armature coil wounding unit individual piece aggregate in a resin molding, and an electric motor.SOLUTION: A shaft 2 is installed in an armature 1 formed by burying an armature coil wounding unit individual piece aggregate in a resin molding, the shaft 2 is rotatably supported with a pair of shaft bearings 3, and there are arranged a bracket 5A on an output shaft side, holding an outer ring of each of the shaft bearings 3, and a bracket 5B on a brush holding case side. A magnet 4 is arranged in a magnet holding part of the bracket 5A on the output shaft side. Similarly, a brush holding case 6 is arranged in a brush holding case housing part of the bracket 5B on the brush holding case side. The armature 1 is formed by burying the armature coil wounding unit individual piece aggregate in the resin molding 7. The resin material of the resin molding 7 is an unsaturated polyester resin composition containing at least pentaerythritol tetra stearate.SELECTED DRAWING: Figure 1
