PROBLEM TO BE SOLVED: To reduce a load applied to a bridge, supporting the outer peripheral surface of a core between a pair of permanent magnet housing sections and the outer peripheral surface of a rotor core, while suppressing demagnetization of the permanent magnet, and to increase torque.SOLUTION: Second positioning surfaces 412a, 422a are located closer to the core outer periphery 26 side than first positioning surfaces 411a, 421a. End faces 311c, 321c of first magnetic materials 311, 321 on the second magnetic materials 312, 322 side are located closer to the second magnetic materials 312, 322 side than stepped surfaces 41d, 42d. End faces 312c, 322c of the second magnetic materials 312, 322 on the first magnetic materials 311, 321 side are abutted against the end faces 311c, 321c of the first magnetic materials 311, 321 on the second magnetic materials 312, 322 side. |
