PROBLEM TO BE SOLVED: To provide a method of manufacturing a rotor, with which a magnet can securely be fixed to a rotor core with resin and the rotor core can be prevented from being broken. SOLUTION: When a size between an end face 12a of the rotor core 12 and an end face 11a of a permanent magnet 11 is set to be an inter-core end face magnet sizeδ, melted resin 13 is implanted into a slot 12s from a cylinder 23, and a minimum value of a size between an inner peripheral face of the slot 12s and a side of the permanent magnet 11, with which resin 13 can be filled, is set to be a minimum size value between slot magnets, melted resin 13 is implanted into the slot 12s and injection molding is performed with a condition that the value of the inter-core end face magnet sizeδis set to be not less than the minimum size value between slot magnets. Thus, the permanent magnet 11 is fixed to the rotor core 12. COPYRIGHT: (C)2007,JPO&INPIT |
