Patent ID: 7521828

Claim:
A segment connection type electric rotating machine comprising: a stator coil comprising: phase coils each of which includes a U-shaped segment continuum formed by U-shaped conductor segments inserted into slots of a stator core from one of end surfaces of the stator core with respect to an axial direction of the stator core and connected to one another at the other one of the end surfaces, an I-shaped leading conductor segment inserted into one of the slots and connected to a lead end of the U-shaped segment continuum at the other one of the end surfaces, and an I-shaped terminating conductor segment inserted into one of the slots and connected to a terminal end of the U-shaped segment continuum at the other one of the end surfaces; a connector box fixed to an outer periphery of the stator core; and a power supply lead laid between the connector box and the I-shaped leading conductor segment, the power supply lead being welded at a tip portion thereof to an end portion of the I-shaped leading conductor segment in the vicinity of an axial end of the stator coil; wherein the U-shaped conductor segments are made of rectangular wire, and the power supply lead is made of round wire, and wherein the end portion of the I-shaped leading conductor segment includes a portion extending in a circumferential direction of the stator core over the axial end of the stator coil, and the tip portion of the power supply lead includes a portion extending in the circumferential direction over the axial end of the stator coil.
