  • Stator for use in electric rotating machine
    Patent number: 8344573
    Abstract: A stator for use in an electric rotating machine is provided which includes a stator winding wound through slots of a stator core. The stator winding is made up of a plurality of conductor segments connected together. Each of the conductor segments includes an in-slot portion disposed inside one of the slots and out-slot portions extending from the in-slot portion outside at least one of the ends of the stator core. Ends of the out-slot portions are joined together to form the stator winding. The joints of the ends of the out-slot portions have a given pattern of texture formed on surfaces thereof and coated with an insulating material. The pattern of texture enhances the adhesion of the insulating coatings to the surfaces of the joints and ensures the stability in electric insulation of the joints.
