ROTOR AND INTERIOR PERMANENT MAGNET MOTOR

摘要

This rotor for constructing an interior permanent magnet motor is equipped with: magnets (2-1 to 2-6) to be inserted into the rotor; and rotor core (1) on which magnet insertion holes for inserting the magnets (2-1 to 2-6) are formed. The magnet insertion holes are formed such that when the magnets (2-1 to 2-6) are inserted, air gaps (21, 22) are formed in both end regions of the magnets (2-1 to 2-6) in the circumferential direction, except at both ends of the surfaces of the magnets on the inner circumference side.
