できるという優れ友効果を発揮する。According to the present invention, since the portion of the armature winding that is inserted into the slot has a rectangular shape in accordance with the shape of the slot, it is possible to obtain an armature for a rotating electric machine with low magnetic resistance, and also Even if the end parts overlap in multiple layers, since the end parts have a circular shape, the bulge is smaller than that of a rectangular shape, so the end parts do not become long, and therefore the internal resistance of the armature winding can be reduced. At the same time, it has the advantage of being able to downsize the armature of a rotating electric machine.
