MOTOR ROTOR, MOTOR, MOTOR-ROTOR MANUFACTURING METHOD, AND AIR-CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a motor rotor that suppresses electric corrosion of a rolling bearing without impairing productivity and quality by arranging a resin part, integrally molding a rotor magnet and a shaft or the like, while extending the resin part as far as a point between the shaft and the rolling bearing.

SOLUTION: A motor rotor 20 is configured such that a position-detecting resin magnet 25 and a shaft 23 are integrally molded by a resin part 24 while the shaft 23 is arranged with a load-side rolling bearing 21a and an anti-load side rolling bearing 21b. In the motor rotor 20, integration by the resin part 24 is executed in such a manner that the resin part 24 is interposed between the shaft 23 and the anti-load side rolling bearing 21b.
