Patent ID: 7737594

Claim:
An axial gap motor comprising: a rotor; and a pair of stators which are arranged to face each other and hold the rotor from both sides thereof along a rotation axis, wherein the rotor includes: electromagnets as main magnets, and arranged along a circumferential direction so that directions of magnetic fluxes thereof are parallel to the rotation axis; and sub permanent magnets arranged in the vicinities of circumferential end portions of the main magnets, and are magnetized orthogonal to the rotation axis and a radial direction, and wherein: the sub permanent magnets which are adjacent to each other along the circumferential direction are arranged so that the same poles thereof face each other; and a pair of the sub permanent magnets which are adjacent to each other along the circumferential direction is disposed so as to be shifted from the electromagnets to either side thereof along the rotation axis.
