PROBLEM TO BE SOLVED: To provide a permanent magnet rotary motor for reducing a cogging torque and preventing increase in copper loss. SOLUTION: A combination of first and second split core units 13, 15 constitutes a stator core 9. The first split core unit 13 constitutes a yoke 17. The second split core unit 15 integrally constitutes a plurality of pole posts 25 and a plurality of links 29A, 29B for mutually linking a magnetic plane composing section 27 and two adjacent magnetic plane constituting sections 27. A thickness of the link 29A is smaller than a thickness of the link 29B in the radial direction. COPYRIGHT: (C)2007,JPO&INPIT
