Abstract
The problem is to provide an axial gap motor using non-rare-earth magnets, as an axial gap motor capable of suppressing reduction in magnet torque and increasing reluctance torque. A solution to the problem is given by an axial gap motor, which has a rotor, and a pair of statorsarranged opposite to the rotorso that the rotoris sandwiched between the stators through a gap G in a direction of rotation axisof the rotor, in which the rotorhas a plurality of non-rare-earth magnetsarranged as separated from each other along a circumferential direction around the rotation axis, and a plurality of magnetic membersarranged through a non-magnetic memberor the like between the plurality of non-rare-earth magnets, in which the magnetic permeability of the plurality of magnetic membersis larger than that of the plurality of non-rare-earth magnets, and in which the plurality of non-rare-earth magnetsand the plurality of magnetic membersdefine opposite facesS of the rotorto the pair of stators
