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.
