Abstract: A rotating electric machine includes a rotor and a stator. The stator includes a stator core and a three-phase stator coil comprised of a plurality of star-connected phase windings. The phase windings are partially received in slots of the stator core to form a pair of coil ends which respectively protrude from opposite axial end faces of the stator core. Each of the phase windings is comprised of a plurality of winding segments. The stator coil also has a plurality of intraphase bridging wires electrically connecting the winding segments of the same phase and a plurality of interphase bridging wires electrically connecting neutral point-side ends of the phase windings. All of the intraphase and interphase bridging wires are arranged on one of the coil ends so that at least one of the intraphase bridging wires is in direct contact with at least one of the interphase bridging wires.

Abstract: In a stator having a stator core and phase windings, slots are formed in the stator core and each slot accommodates conductors in a layer structure from one end to the other end of the slot in a radial direction of the stator core. The phase windings in one phase have conductors accommodated in a first slot and a second slot which are adjacently formed in the stator core. An electrical connection between the conductors in a n-th layer and the conductors in a (n+1)-th layer includes that the conductors accommodated in the first slot are electrically connected together, the conductors accommodated in the second slot are electrically connected together, and the conductors accommodated in the first slot are electrically connected with the conductors accommodated in the second slot. This connection eliminates a phase difference in the first slot and the second slot in a distributed winding structure.

Abstract: A rotating electric machine includes a rotor, a stator and an Insulating resin. The stator includes a stator core and a stator coil that is partially received in slots of the stator core so as to have a pair of coil end parts protruding outside of the slots respectively on opposite axial sides of the stator core. The stator coil is formed of a plurality of electric wire segments, each of which includes an electric conductor and an Insulating coat that covers an outer surface of the electric conductor. The insulating resin is applied to the coil end parts of the stator coil so as to cover the outer surfaces of the insulating coats of the electric wire segments forming the stator coil. Further, a tensile strength of the insulating coats of the electric wire segments is higher than an adhesion strength between the insulating resin and the insulating coats.
