Rotary electric machine

A rotary electric machine comprising:

• a stator including
• a stator core in which a plurality of slots are formed by a plurality of teeth that extend radially inward from an annular core back so as to leave a spacing in a circumferential direction, and
• an armature winding that comprises a plurality of coil portions that are mounted to said teeth of said stator core;
• and
• a rotor that is disposed inside said stator so as to have a magnetic air gap portion interposed, and that rotates around a rotating shaft, wherein
• the number of identical-phase coil portions among said coil portions in said armature winding is n, where n≥3, and in a series coil portion group that includes m of said coil portions that are serially connected, where m≤n, where a largest electrical angular phase difference between two of said coil portions in said series coil portion group is θm, an electrical angular phase difference of a first of said coil portions in said series coil portion group is θ1=0°, and respective electrical angular phase differences of remaining coil portions relative to said coil portion that has an electrical angular phase difference of θ1 are θ2, θ3, etc., through θm in increasing order, and
• the numbers of turns of conducting wire in said coil portions that have an electrical angular phase difference of θk that satisfies θ1<θk<θm, where k=2, 3, etc., through m−1, are greater than the numbers of turns of conducting wire in said coil portions that have electrical angular phase differences of θ1 and θm, and are also greater than the numbers of turns of conducting wire in said coil portions that are adjacent to said coil portions that have said electrical angular phase differences of θk on two sides in a circumferential direction of said stator core, and phases of said coil portions that have said electrical angular phase differences of θk are also different than phases of each of said coil portions that are adjacent to said coil portions that have said electrical angular phase differences of θk on said two sides in said circumferential direction.
