PERMANENT MAGNET MOTOR, HERMETIC COMPRESSOR, AND REFRIGERATING CYCLE DEVICE

摘要

The gap between the inner peripheral end part of each slit (54) and each magnet storage hole (52) in a rotor (12) is set small, and the gap between the outer peripheral end part of each slit and the outer peripheral edge of the rotor (12) is set small. The gap (Wn) between the inner peripheral end parts of the adjacent slits (53) is distributed in proportion to the area of a half sinusoidal wave corresponding to the positions (?1, ?2...?n) of the outer peripheral end parts of the slits (54).
