Patent ID: 8049389

Claim:
An axial gap motor comprising: a rotor which rotates around a rotational axis; and a stator which is disposed on at least one side in a rotational axis direction of the rotor in such a manner as to confront the rotor, wherein the rotor comprises a rotor frame, a plurality of main magnet portions which are magnetized in the rotational axis direction and are disposed in a circumferential direction and a plurality of magnetic members which are disposed individually on surfaces of the main magnet portions which face the at least one side in the rotational axis direction of the main magnet portions, wherein the magnetic members have fitting portions extending away from at least one of an outer circumferential surface and an inner circumferential surface of the magnetic members in a radial direction of the rotor and are configured to fittingly engage the rotor frame, and wherein the rotor frame comprises a plurality of ribs which are disposed at predetermined intervals in the circumferential direction and which extend in the radial direction, a shaft portion which is provided at inside diameter sides of the plurality of ribs, and a rim portion which is provided at outside diameter sides of the plurality of ribs, wherein the plurality of main magnet portions are disposed individually between the ribs which lie adjacent to each other in the circumferential direction, wherein the magnetic members are disposed on both sides in the rotational axis direction of the main magnet portions, wherein the rotor further comprises support plates which each hold the main magnet portion and the pair of magnetic members from a radial side thereof, wherein a plurality of magnetic pole units each unitizing the main magnet portion and the pair of magnetic members are configured by the support plates, and wherein the fitting portions of the magnetic members fit in the support plates which are supported by the rotor frame.
