摘要:
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 10, which has a rotor 11, and a pair of stators 21 arranged opposite to the rotor 11 so that the rotor 11 is sandwiched between the stators through a gap G in a direction of rotation axis 11a of the rotor 11, in which the rotor 11 has a plurality of non-rare-earth magnets 13 arranged as separated from each other along a circumferential direction around the rotation axis 11a, and a plurality of magnetic members 15 arranged through a non-magnetic member 17c or the like between the plurality of non-rare-earth magnets 13, in which the magnetic permeability of the plurality of magnetic members 15 is larger than that of the plurality of non-rare-earth magnets 13, and in which the plurality of non-rare-earth magnets 13 and the plurality of magnetic members 15 define opposite faces 11S of the rotor 11 to the pair of stators 21.
