Abstract: An armature winding of a rotary electric machine includes multi-phase windings. The phase winding of each phase includes a plurality of series-connected parts of the winding segments, and the series-connected parts are connected in parallel to form the phase winding. The winding segments include a first winding segment and a second winding segment, both having coil resistance different from each other. Each of the series-connected parts is formed by connecting the first winding segment and the second winding segment in series.
