摘要： 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.

摘要： A rotor core is configured by arranging divided rotor cores coaxially so as to be in close contact with each other such that magnetic pole centers are aligned axially, auxiliary grooves are recessed into respective outer circumferential surfaces of the divided rotor cores between respective magnetic poles so as to have plane symmetry relative to a plane that includes a center position between the magnetic poles and a central axis of the divided rotor cores, and so as to extend from a first axial end to a second axial end of the divided rotor cores, the auxiliary grooves recessed into an outer circumferential surface of an identical divided rotor core have an identical groove shape, and groove widths of the auxiliary grooves are set such that predetermined orders of harmonic components of cogging torque that result from each of the divided rotor cores mutually cancel each other out.
