Abstract
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.
