1. A stator of a rotary electric machine comprising a stator winding and a stator core having a plurality of slots in which portions of the stator winding are disposed, wherein the stator winding comprises:

  • a plurality of series-connected regular segments having a pair of in-slot portions inserted into a regularly disposed pair of the slots and a turn portion; and

    a plurality of irregular segments having a pair of in-slot portions disposed in a pair of slots whose location is suitable to connect the regular segments to form the stator winding and a continuous crossover portion crossing over some of the regular segments, and wherein;

    the turn portions of the regular segments have portions extending along a center axis of the stator core between a top thereof and one end of the stator core; and

    the continuous crossover portion has a hang-down portion in contact with the portions of the regular segments extending along the center axis so as to reduce bending stress.
