Abstract
A rotary electric machine stator includes a stator core having plural slots and a stator winding that is composed of plural conductor segments. Each conductor segment has a straight portion disposed in the slot and connection ends projecting from the slots and welded to another. The connection ends to be welded cross each other at an angle larger than zero degree.
Claims4
A method of manufacturing a rotary electric machine stator comprising steps of:
- inserting straight portions of conductor segments into a plurality of slots of a stator core;
- bending said conductor segments so that connection ends of said conductor segments that are disposed adjacent to each other in a radial direction can incline in opposite circumferential directions to cross one another;
- and
- welding pairs of said connection ends crossing each other.

A method of manufacturing a rotary electric machine stator comprising the steps of:
- inserting straight portions of conductor segments into a plurality of slots of a stator core in a plurality of radial layers in each slot so that end portions of said straight portions project from the slots in said radial layers;
- bending said end portions so that said end portions in adjacent layers incline in opposite circumferential directions to cross one another;
- and
- welding said end portions that cross each other together.
