Abstract:
In an axial gap motor, a rotor is rotatably supported and a stator is placed to face the rotor with a gap in a first direction parallel to a shaft of the rotation. A core of the stator is formed by stacking of thin plates that can be penetrated by magnetic flux in a second direction orthogonal to the first direction. A plurality of thus formed cores are fixed to a yoke. Here, each of the plurality of cores includes a plurality of fitting portions in positions at a side facing the yoke, and the yoke includes a plurality of attachment portions corresponding to the plurality of fitting portions of the core in positions in which each core is fixed.
