Patent ID: 8659199

Claim:
A rotor used for an axial gap permanent magnet motor in which a stator and the rotor are oppositely arranged having a gap between the stator and the rotor in a direction parallel to a rotary shaft, comprising: a plurality of permanent magnets that are magnetized in a rotary shaft direction respectively and arranged along a circumferential direction of the rotary shaft to form field magnetic poles; a plurality of soft magnetic material segments each of which is provided so as to cover at least a stator-facing surface in each of the permanent magnets to form a permanent magnet/soft magnetic material composite part including the permanent magnet and the soft magnetic material segment; and a disc-shaped nonmagnetic molded frame that is molded so as to cover a periphery of the permanent magnet/soft magnetic material composite parts while leaving at least the stator-facing surfaces of the soft magnetic material segments as exposed surfaces, wherein the permanent magnet/soft magnetic material composite parts are integrated with the disc-shaped nonmagnetic molded frame by molding of the disc-shaped nonmagnetic molded frame, wherein side surfaces of each of the soft magnetic material segments are provided with at least one of a projection engaged with the nonmagnetic molded frame or a recessed portion engaged with a part of the nonmagnetic molded frame, wherein the at least of a projection is provided along the circumferential direction of the soft magnetic material segment and doesn't contact with the permanent magnet.
