Abstract

See full text

The moldability of the stator of an axial gap type rotating electric machine improved. The axial gap type rotating electric machine has: a stator comprising core members disposed about a rotating shaft in a ring shape with a predetermined space from adjacent core members, said core members each having a core around which a coil is wound, the number of the turns of the coil being less on the outer perimeter side than on the inner perimeter side, the core members being molded with mold material; and a rotor facing an end surface of the core in the shaft direction through a predetermined gap. The core members comprise: a first core member in which the number of coil winding layers on one side in the shaft direction is larger than the number of winding layers on the other side; and a second core member in which the number of coil winding layers on one side in the shaft direction is less than the number of winding layers on the other side. In the stator, the first and second core members are alternately disposed, with the coil on the side where the number of the winding layers of the first core member is larger and the coil on the side where the number of the winding layers of the second core member is smaller opposed to each other.
