ELECTRIC MOTOR ROTOR, ELECTRIC MOTOR, AIR CONDITIONER, AND PRODUCTION METHOD FOR ELECTRIC MOTOR ROTOR

摘要

An electric motor rotor is provided that can suppress electrolytic corrosion of a roller bearing without damaging productivity and quality because a resin section for integrally molding a rotor magnet, a shaft, and the like is arranged to extend up to between the shaft and the roller bearing. An electric motor rotor 20 according to the present invention is the electric motor rotor 20 in which a resin magnet for position detection 25 and a shaft 23 are integrally molded by a resin section 24 and a load side roller bearing 21a and a counter load side roller bearing 21b are arranged in the shaft 23. The integration by the resin section 24 is performed such that the resin section 24 is interposed between the shaft 23 and the counter load side roller bearing 21b.
