摘要： A rotor includes a core and two or more ribs. The core has a through hole group that includes three or more through holes arranged in a circumferential direction. The through hole group is formed through a predetermined magnetic pole. The two or more ribs are configured as portions of the core, with each rib being interposed between adjacent through holes. A first of the ribs has a first inclination with respect to a magnetic pole centerline. A second of the ribs has a second inclination with respect to the magnetic pole centerline. The second inclination is larger than the first inclination. The magnetic pole centerline is a straight line that passes through a radial center line of the magnetic pole and an axial center of the rotor. The first rib is narrower than the second rib.

摘要： Satisfactory magnet torque is achieved while avoiding a reduction in the reluctance torque generated. The rotor core is provided with a plurality of magnet slots arranged in the circumferential direction of the rotor core and a gap formed of base holes and a projecting hole. The base holes extend from both ends in the circumferential direction of each magnet slot to the outer side of the rotor core. The projecting hole projects in the circumferential direction of the rotor core from at least one of peripheral portions, opposed to each other, of the base holes provided at both of the ends of the magnet slot, when viewed in an axial direction. The projecting hole is located closer to the magnet slot than to an outer peripheral side end of the base hole.
