Abstract
In the armature winding of a rotary electric machine, in a series coil portion group, the numbers of turns of conducting wire in the coil portions that have an electrical angular phase difference of θk that satisfies θ1<θkθm are different than the numbers of turns of conducting wire in the θ1 and θm coil portions, and are also different than the numbers of turns of conducting wire in the coil portions that are adjacent to the θk coil portions on two sides in a circumferential direction of the stator core, and phases of the θk coil portions are also different than phases of each of the coil portions that are adjacent to the θk coil portions on the two sides in the circumferential direction.
