Stator and rotating electric machine
Abstract:
A stator includes an annular stator core, a stator coil and a resin adhesive. The stator coil is comprised of a plurality of electric wires. The electric wires are partially received in slots of the stator core so that the stator coil has a pair of coil end parts protruding outside the slots respectively from opposite axial end faces of the stator core. The resin adhesive is filled in the slots of the stator core and/or applied to the coil end parts of the stator coil. Moreover, each of the electric wires includes an electric conductor and an insulating coat that covers an outer surface of the electric conductor. The insulating coat is two-layer structured to include an inner coat and an outer coat. The adhesion strength of the outer coat to the resin adhesive is lower than the adhesion strength of the inner coat to the resin adhesive.
