1. A rotary electric machine comprising a stator of a distributed winding type including a plurality of first slots, in each of which winding wires of a plurality of same phases or winding wires of one phase are arranged, and a plurality of second slots, in each of which winding wires of a plurality of different phases are arranged, wherein
a total number of turns in each of the first slots is same as one another, a total number of turns in each of the second slots is same as one another, and when a number of poles is represented as P, a number of slots is represented as S, a number of phases of a power supply is represented as m, and a number of slots in each pole and each phase is represented as q=S/P/m, the number of slots q in each pole and each phase is 2i (i is an integer equal to or larger than 1), and i pieces of the first slot and i pieces of the second slot are alternately arranged, and a ratio of the total number of turns in each of the first slots and the total number of turns in each of the second slots is 0.85√(3):2 to 1.15√(3):2. |
