Abstract:
There is provided an axial gap motor including a rotor rotatable around a rotation axis; and a first stator and a second stator arranged to face each other with the rotor therebetween from both sides of the rotor in the rotation axis direction of the rotor, wherein the rotor includes a plurality of main permanent magnets having magnetizing directions in the rotation axis direction of the rotor and arranged in a peripheral direction of the rotor; a partition member arranged between the main permanent magnets which are adjacent to each other in the peripheral direction of the rotor, the partition member including a nonmagnetic material; and auxiliary permanent magnets having a magnetizing direction that is orthogonal both to the rotation axis direction of the rotor and a radial direction of the rotor, and arranged on both sides of the partition member in the rotation axis direction of the rotor.
