Abstract
A rotating electrical machine includes a stator and a rotor. The stator winding includes a plurality of conductor segments inserted through the slots from one end surface of the stator core with end portions of the conductor segments projecting out beyond another end surface of the stator core. The conductor segments include an undeformed portion, a plastically deformed portion formed at the end portions thereof and a tapered portion. The plastically deformed portion has a dimension of the plastically deformed portion along a circumferential direction that is greater than a dimension of the undeformed portion along the circumferential direction and so that a dimension of the plastically deformed portion along a radial direction is smaller than a dimension of the undeformed portion along the radial direction. The conductor segments are welded together at tops of the plastically deformed portions thereof.
