PROBLEM TO BE SOLVED: To provide a stator for a rotary electric machine, capable of suppressing an increase in loss by suppressing generation of an eddy current flowing through a bus bar fitting pin press-fitted in a fitting hole of a stator core.SOLUTION: A stator 20 includes: a stator core 30 having a plurality of slots 31 in a peripheral direction; a stator winding 40 composed of three-phase phase windings 41U, 41V, 41W wound around the stator core 30; and a bus bar module 60 including three phase bus bars 61U, 61V, 61W respectively electrically connected to respective phase windings and a plurality of fitting pins 67 to be respectively press-fitted to a plurality of fitting holes 35 formed on an axis one-end face of the stator core 30 separately in the peripheral direction. When it is defined that an angle formed by two slots 31 adjacent in the peripheral direction around an axis O of the stator core 30 is set as &thetas;s, an angle &thetas;h formed by two fitting holes 35 adjacent in the peripheral direction around the axis O is determined by &thetas;h≒m(m is a positive integer)×6×n×&thetas;s.SELECTED DRAWING: Figure 8 |
