Abstract

According to one embodiment, an armature winding includes a plurality of rectangular solid conductors and a plurality of rectangular hollow conductors, which are arranged such that tip of end portions thereof form one surface, the surface being coated with a brazing filler material, and an anti-flowing agent applied on a portion of an inner surface of each hollow conductor to prevent the brazing filler material from flowing into hollow portions of the hollow conductors.
