Abstract: To reduce eddy current loss in a supporting member of a rotor of an axial gap motor, and improve efficiency, the motor includes a rotor, and stators arranged opposite to the rotor. The rotor has a disc-shaped supporting member, having a plurality of mounting holes in each of which a permanent magnet segment is installed. In the stators, a plurality of field windings is arranged for generating a rotating magnetic field. The axial gap motor is provided with notches extending radially between each of the mounting holes of the supporting member in which a permanent magnet segment is fitted, and an outer peripheral edge of the supporting member.

Abstract: To reduce eddy current loss occurring to a supporting member of a rotor of an axial gap motor, and improve efficiency of a motor. The axial gap motor of the present invention includes a rotor 10 and stators 20 and 22 arranged opposite to this rotor 10. The rotor has a disk-shaped supporting member 12 on which a plurality of permanent magnet segments 11 is mounted. In the stators 20 and 22, a plurality of field winding slots is arranged for generating a rotating magnetic field.
