ROTOR OF PERMANENT MAGNET MOTOR FOR COMPRESSOR, METHOD FOR MANUFACTURING ROTOR OF PERMANENT MAGNET MOTOR FOR THE COMPRESSOR, COMPRESSOR, AND REFRIGERATION CYCLE

摘要

PROBLEM TO BE SOLVED: To provide the rotor of a permanent-magnet motor for compressors which rotor is provided with improved iron loss and the like for enhanced efficiency, produces less noise, requires lower cost, and is satisfactory in ease of assembly. SOLUTION: A pole-anisotropic ring magnet is placed in a rotor and a rotary shaft and the pole-anisotropic ring magnet are integrally molded using resin.
