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.

Abstract: A stator includes an annular stator core and a three-phase stator coil. The stator coil is comprised of a plurality of star-connected phase windings. The stator coil further has a plurality of interphase bridging wires to electrically connect neutral point-side ends of the phase windings to each other. The interphase bridging wires are arranged on a coil end of the stator coil. At least one of the interphase bridging wires is made up of at least one busbar. The busbar includes three or four connecting end portions each having a joining surface joined to one of the phase windings, other bridging wires and other busbars. The connecting end portions are arranged so that some of the joining surfaces of the connecting end portions face substantially in the circumferential direction of the stator core, while the other joining surfaces face substantially in a radial direction of the stator core.

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.
