An axial gap motor includes a rotor rotatable about a rotation axis, and a stator disposed opposing to the rotor from at least one side in a rotation axis direction, wherein the rotor includes: a rotor frame including a plurality of ribs extending in a radial direction, an inner circumferential side annular shaft, and an outer circumferential side annular rim, which are integrally coupled to each other through the ribs; a plurality of main magnets magnetized in the rotation axis direction, and having a main magnet piece disposed between a pair of the ribs which are adjacent to each other in a circumferential direction; and a plurality of sub magnets magnetized in a direction perpendicular to the rotation axis direction and the radial direction, and having sub magnet pieces disposed on at least one side of the rib in the rotation axis direction, the shaft has shaft side rib mounting holes through which the ribs are mounted, the rim has rim side rib mounting holes through which the ribs are mounted, the ribs have radial inner ends mounted and fixed into the shaft side rib mounting holes and radial outer ends mounted and fixed into the rim side rib mounting holes, and in the rotor frame, the main magnets and the sub magnets are alternately disposed in the circumferential direction, between the shaft and the rim. |
