Method of manufacturing rotary electric machine's stator

Abstract

A method of manufacturing a stator of a rotary electric machine is comprised of the following steps: providing a plurality of U-shaped basic conductor segments and a plurality of U-shaped connection conductor segments; forming the U-turn portions and straight portions into crossover portions, inserting the pair of straight portions of the basic and connection conductor segments into prescribed two slots of a stator core from one end thereof to extend from the other end, bending one of the pair of straight portions in the direction opposite to the other of the pair of extended straight portions so that the edges of straight portions extending from the prescribed slots can adjoin each other, connecting the adjoining edges to form a plurality of phase coils, and removing the U-turn portion of the connection conductor segments to form terminals of the phase coils.
