摘要:
Provided is a motor capable of increasing a torque while suppressing an increase in the physical size of the motor. A motor includes a rotor. The rotor includes pairs of magnet slots evenly spaced in a circumferential direction, each pair of magnet slots being arranged in a V-shape, pairs of main magnets housed in the pairs of magnet slots, and a plurality of auxiliary magnets including an outer magnet housed in an outer end in the circumferential direction in each of the pairs of magnet slots. The motor satisfies at least one of a first condition that the main magnets are sintered magnets and the auxiliary magnets are bonded magnets, or a second condition that magnetization directions of the main magnet and the outer magnet housed in the same magnet slot intersect outside in the radial direction so as to define an acute angle.
