Abstract:
An axial gap motor includes: a rotor; and a stator, wherein: the rotor includes a plurality of main permanent magnet parts and a plurality of auxiliary permanent magnet parts, the auxiliary permanent magnet parts being disposed near an end portion of each of the main permanent magnet parts and a magnetizing direction of each of the auxiliary permanent magnet parts corresponding to a direction perpendicular to the direction of the rotational axis; each of the stators includes a plurality of teeth arranged in a circumferential direction and protruding toward the rotor along the rotational axis, and a circumferential distance between a circumferential direction first end and a circumferential direction second end of each of the auxiliary permanent magnet parts on a surface opposite the stator is larger than a slot width of a slot defined between the teeth adjacent in the circumferential direction.
