Abstract
The segment connection type electric rotating machine includes a stator coil constituted by phase coils each of which includes a U-shaped segment continuum formed by U-shaped conductor segments inserted into slots of a stator core, an I-shaped leading conductor segment inserted into one of the slots and connected to a lead end of the U-shaped segment continuum, 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. A connector box fixed to the outer periphery of the stator core. A power supply lead is laid between the connector box and the I-shaped leading conductor segment. The power supply lead is welded at a tip portion thereof to an end portion of the I-shaped leading conductor segment in the vicinity of head-side coil ends of the stator coil.
