PROBLEM TO BE SOLVED: To provide a method of molding a Lundell-type core for a rotary electric machine, wherein the permanent magnet locking section can be molded accurately by a simple processing and a magnet can be inserted from the axial end. SOLUTION: The permanent magnet locking section is provided, in such a manner that when the claw magnetic poles of a pair of Lundell-type cores are meshed alternately while inverting one core, the magnet mounting surface and the flange of one of the adjoining claw magnetic poles are arranged to face the magnet mounting surface and the flange of the other claw magnetic pole, and a magnet insertion space into which a magnet can be inserted from either axial end is formed. The magnet inserted from the axial end side is locked to the magnet-locking section in the magnet insertion space. COPYRIGHT: (C)2011,JPO&INPIT |
