摘要:
A rotary electric machine includes a stator that has a plurality of slots accommodating a coil having a lap winding configuration made of a segment conductor, and a rotor that faces the stator and has a plurality of magnetic poles, and has a fractional slot configuration in which the number of slots per pole and phase is more than 1/2, and a denominator is equal to or more than 2 in an irreducible fraction expression. When the irreducible fraction expression of the number of slots per pole and phase is set as (a+b/c) where a indicates zero or a positive integer, and b and c indicate a positive integer and b
