摘要： PROBLEM TO BE SOLVED: To provide a core capable of suppressing cogging torque.
SOLUTION: Tees 13 are extending radially, at a constant angular interval, from the center of a core sheet 11. A bending piece 14 (a long bending piece 14a and a short bending piece 14b) is formed at the forward end (outer diameter side) of each tees 13. Surface and rear surface of the core sheet 11 are laminated alternately sheet by sheet thus forming a core 21. Even if the bending piece 14 (a long bending piece 14a and a short bending piece 14b) is bent at a cut part 15, gaps are not formed continuously in the laminating direction of the core sheet 11. Consequently, a suitable magnetic circuit is formed in the core 21 and increase of reluctance can be suppressed. Since the base ends of respective tees 13 are coupled at a coupling part 16, increase of reluctance can be suppressed and thereby cogging torque does not increase.
