ABSTRACT:
The present axial gap motor is provided with: a rotor that is rotatable around a rotation axis; and a pair of stators that are opposed to each other with the rotor interposed therebetween from both sides in a rotation axis direction which is parallel with the rotation axis of the rotor. The rotor includes: a plurality of main magnets arranged in a circumferential direction so that a flux direction is parallel with the rotation axis direction; a sub permanent magnet which is disposed in the vicinity of a circumferential end portion of the main magnet and is magnetized in a direction perpendicular to the rotation axis direction and a radial direction; and a magnetic member which is provided on a surface of at least one of the one side and the other side in the rotation axis direction of the main magnet. A length of the magnetic member in the rotation axis direction is larger than a length of the sub permanent magnet in the rotation axis direction.
