(57) [Problem] The present invention improves corrosion resistance and insulation, and improves assemblability and productivity. The stator of the alternator in which the contact of the ground connection is eliminated. SOLUTION: A stator winding is formed by winding a wire 30 such that an inner layer and an outer layer are alternately taken in a slot depth direction in a slot 15a for every six slots in a first turn. A first winding group in which six windings are arranged at one slot pitch, and a one-turn second winding in which the element wire 30 is reversely wound with the first winding shifted by 180 degrees in electrical angle. It has two sets of winding assemblies composed of a pair with a second winding group in which six wires are arranged at one slot pitch, and connects the windings to form two sets of three-phase AC windings. It is configured. And The same address connection (C1-1) of the three-phase AC windings of each set is arranged at an 8-slot pitch. |
