PROBLEM TO BE SOLVED: To provide a motor capable of suppressing fluctuation of an effective magnetic flux that is generated in a rotor by a temperature change.SOLUTION: The motor comprises: back magnet parts 53 and 54 disposed in a gap generated between backs of claw-like magnetic poles 32 and 42; and an inter-pole magnet part 55 disposed in a gap generated in a circumferential direction between the claw-like magnetic poles 32 and 42. The back magnet parts 53 and 54 are configured using an SmCo-based magnet material, the inter-pole magnet part 55 is configured from an SmFeN-based magnet material, and magnet materials of different characteristics are used for the back magnet parts 53 and 54 and the inter-pole magnet part 55.SELECTED DRAWING: Figure 5 |
