Abstract
A stator for an electric rotating machine is provided which includes a stator winding made up of a plurality of conductor segments. Each of the conductor segments has a leg which includes an in-slot portion into one of slots of a stator core and a protrusive end extending outside the slot. The protrusive ends of the conductor segments are welded together to form a stator winding. The conductor segments are broken down into first conductor segments and second conductor segments. The protrusive ends of the first and second conductor segments include outwardly-oriented bends and inwardly-oriented bends for increasing an interval between every pair of adjacent two of the protrusive ends to be welded, thus ensuring a required degree of electrical insulation between the pairs of the protrusive ends and permits the height of a coil end of the stator winding to be decreased.
