Abstract
Permanent magnets that constitute the single magnetic poles are constituted by n permanent magnet segments, the n permanent magnet segments being configured such that shapes and directions of orientation thereof have mirror symmetry relative to a plane that passes through a magnetic pole center and that includes a central axis of the rotor core, and being oriented such that a permanent magnet segment that is further away from the magnetic pole center in a circumferential direction has a smaller angle of orientation, and the permanent magnet segment that is positioned further away from the magnetic pole center in the circumferential direction being produced so as to have an approximately fan-shaped cross-sectional shape in which a radial width is wider than a circumferential width.
