Abstract:
This axial gap motor includes: a stator; and a rotor provided so as to be opposed to the stator in an axial direction. The rotor includes an annular rotor yoke, and a plurality of magnets provided to contact one surface of the rotor yoke so as to be arranged at predetermined intervals along a circumferential direction with magnetic poles thereof being different alternately. The one surface includes a plurality of facing areas facing and contacting the plurality of magnets, and a non-facing area not facing the plurality of magnets. The non-facing area includes partial areas each located between a pair of the facing areas adjacent to each other in the circumferential direction among the plurality of facing areas. The partial areas are formed to be recesses recessed in the axial direction relative to the facing areas.
