Patent ID: 8884487

Claim:
A stator for an electric rotating machine comprising: an annular stator core which has a plurality of slots arrayed in a circumferential direction thereof, the stator core having a first end surface and a second end surface opposed to the first end surface in an axial direction thereof; and a stator winding made up of a plurality of conductor segments, each of the conductor segments being bent to have a head and legs extending from the head, the legs of each of the conductor segments being inserted through the different slots, respectively, so that each of the conductor segments has ends of the legs thereof protruding from either one of the first and second end surfaces of the stator core and the head thereof protruding from the other of the first and second end surfaces of the stator core, wherein the ends of the legs which protrude from either of the first and second end surfaces are arranged in a plurality of radial arrays extending in a radial direction of the stator core, wherein every two of the ends of the legs which are located adjacent each other in each of the radial arrays are provided as a coil end pair, wherein adjacent two of the coil end pairs in each of the radial arrays are arranged away from each other across at least one of the heads of the conductor segments, wherein the ends of each of the coil end pairs are welded to form the stator winding; wherein a connection is made between one of the ends of the conductor segments that protrudes from one of the first and second end surfaces of the stator core to one of the ends of the conductor segments that protrudes from the other of the first and second end surfaces of the stator core, wherein the connection is joined by ends of a second conductor segment that is different in shape from said conductor segments; and wherein the second conductor segment is an S-shaped conductor segment.
