Axial gap type dynamo-electric machine
There is provided an axial gap type rotating electric machine which is small-sized and achieves a high motor efficiency as a drive source having a high torque using, for example, a strong magnet by reducing an energy loss by an induced current. An axial gap type rotating electric machine having a yoke on a side of a rotor in a circular plate shape fixed to a rotating shaft, a yoke 23 on a side of a stator in a circular plate shape opposed to the yoke on the side of the rotor, a magnet fixed to a side of an opposed face of either one of the yokes on the side of the rotor or the side of the stator, a plurality of teeth 24 arranged on a side of an opposed face of other yoke on the side of the rotor or the side of the stator radially and opposedly to the magnet and fixed to the yoke 23 , and a coil wound around each of the plurality of teeth, in which the teeth 24 has a laminated member of plate members 124 for the teeth and faces 124 a to be superposed of the plate members 124 for the teeth are arranged in a circumferential direction.
1. An axial gap type rotating electric machine comprising:
a yoke on a side of a rotor in a circular plate shape fixed to a rotating shaft;
a yoke on a side of a stator in a circular plate shape opposed to the yoke on the side of the rotor;
a magnet fixed to a side of an opposed face of either one of the yokes on the side of the rotor or the side of the stator;
a plurality of teeth arranged on a side of an opposed face of other yoke on the side of the rotor or the side of the stator radially and opposedly to the magnet and fixed to the yoke; and
