Abstract:
An axial-gap dynamo-electric machine is fixed in place without the use of a resin mold, yielding a dynamo-electric machine that exhibits high strength and efficiency. In said axial-gap dynamo-electric machine, in which gap surfaces of a rotor and a stator are perpendicular to the axis of rotation, said stator comprises a plurality of magnetic teeth, a plurality of coils provided on said teeth, and a back yoke. The teeth are inserted in the axial direction into grooves provided in the circumferential direction of the back yoke, and parts of the back yoke are fitted into holes or concavities that extend in the radial directions of the respective teeth, thereby holding the teeth in position in the axial direction.
