A rotor, constituting an interior permanent magnet motor, includes magnets that are inserted into the rotor, and a rotor core containing magnet insertion pockets to which the magnets are inserted, and, when the magnets are inserted, the magnet insertion pockets are formed to provide openings in areas except both ends of an inner circumferential face, at both ends in a circumferential direction of the magnets. |
