ABSTRACT:
In a rotary electric machine stator, a stator coil is formed of plural U-shaped conductor segments. Each of the conductor segments has a U-shaped turn portion disposed at one end of a stator core to form one of said coil ends, a pair of in-slot portion extending from the turn portion and inserted into slots and end portions extending from the in-slot portions to form the other coil end. One of the end portions of one of the U-shaped conductor segments extends straight in an axial direction, and the other bends in a circumferential direction by a predetermined angle to provide a wide cooling surface.
