Abstract
Official abstract text for this publication.
A rotary electric machine is a rotary electric machine including 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 a winding wire 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. The total number of turns in each of the first slots is same as one another. The total number of turns in each of the second slots is same as one another. The total number of turns in the first slot and the total number of turns in the second slot are different from each other.
First claim
Opening claim text (preview).
The invention claimed is: 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 a winding wire 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 a same number, a total number of turns in each of the second slots is a same number, 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. 2. The rotary electric machine according to claim 1 , wherein the 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 0.92√(3):2 to 1.08√(3):2.
