Stator of a rotating electric machine

Abstract

A stator of a rotating electric machine is obtained which has a winding improved in assemblability. The stator has three phase winding 10 which is comprised of respective phase winding sections 11 through 13 electrically connected with each other, the respective phase winding sections 10 through 13 including straight portions 11a through 13a of a rectangular cross section inserted in the slots and connecting portions 11b through 13b connecting between ends of adjacent ones of the straight portions 11a through 13a. The respective phase winding sections includes a plurality of conductor segment units wound in a spiral manner with four corners each bent substantially at right angles. The respective phase winding sections have the straight portions 11a through 13a and the connecting portions 11b through 13b. The conductor segment units are laminated in such a manner that parts of connecting portions 11b through 13b of one of any two adjacent conductor segment units are interposed between adjacent connecting portions 11b through 13b of the other adjacent conductor segment unit, and the conductor segment units are serially linked with one another in a circumferential direction.
