Abstract
In a distribution winding stator using a coil for a rectangular conductor, a coil end is made smaller than before, and the reduction in the current density is aimed, so that a rotary electric machine of a small size and a high power output is obtained. A conductive wire of a rectangular shape in cross section is double-wound, and is allowed to be shifted by the whole width of the wire having double-wound the crowns of both ends, and is formed to crank shape so as to become a length within the range of the intervals of the adjacent slots, so that the conductive wire is formed by being inserted into the slot of the stator.
