ABSTRACT:
There is disclosed a stator structure of an electric rotary machine with a stator winding composed of at least two phase coils wound on a stator core through respective slots formed in the core. In the stator, an elongated insulating strap layer is interleaved between two different phase coils at sites outside the slots such that the width of the strap layer extends in the longitudinal direction of the slots. A plurality of binding yarns pierce through the insulating strap at a distance from one of the opposite side edges which is farther than the other from the slots and bind the stator winding together with a portion of the strap layer lying between each of the pierced portions and said one side edge.
