Abstract
A first stator core and a second stator ore are configured by arranging core block pairs into an annular shape, the core block pairs being configured by stacking together core blocks so as to be spaced apart axially, each of the core blocks including a core back portion and one tooth, and a permanent magnet is configured so as to be divided into a plurality of magnet blocks that each include: a base portion; one shaft portion that protrudes radially inward from an inner circumferential surface of the base portion; and flange portions that protrude on two circumferential sides from a radially inner end portion of the shaft portion, the magnet blocks being held between the core block pairs such that the base portion and the shaft portion are positioned inside the core block pairs and such that the flange portions protrude circumferentially from the core block pairs.
