摘要： A rotary electric machine includes a stator having slots, and a rotor having magnetic poles. When an irreducible fraction expression of the number of slots per pole and phase is set as (a+b/c), the coil for a laps is configured by an adjacent pole coil group, and the coil of a (a+1)th lap is configured by a continuous-pole coil group. In the adjacent pole coil group, the pole coil that is not interposed between adjacent-pole-connection same layer connection portions and the pole coil interposed therebetween are alternately arranged. The continuous-pole coil group is configured only by the pole coil that is not interposed therebetween when the number of blanks is all odd, and by the pole coil that is not interposed therebetween and the pole coil interposed therebetween when the number of blanks is all even or when odd and even numbers are mixed as the number of blanks.
