Abstract
A stator for a rotary electric machine includes: a stator core in a cylindrical shape with plural slots formed at an inner circumferential surface; plural coil segments inserted in the slots from one end surface side of the stator core; and plural coil end plates electrically connected with the coil segments on another end surface side of the stator core, wherein the coil segments respectively include: one leg portion; another leg portion; and a curved portion that is continuously formed between the one leg portion and the other leg portion, wherein the coil end plates respectively include: a plate portion in a flat plate shape; and a pair of extended portions, and wherein end portions of the leg portions of the coil segments are connected to the extended portions. It is possible to improve assembility and attain downsizing by reducing the volume of coil end portions for the stator.
