  • Winding structure for an electrical machine and method for producing the same
    Publication number: 20040135457
    Abstract: The invention relates to a winding arrangement for an electric machine with a polyphase winding, in which a plurality of coils or coil groups connected in parallel (50, 52, 54, 56) are connected with a rotating conductor rail (40, 42, 44, 46). This makes it possible to connect the coil ends directly and without connecting pieces with the electric power supply. The conductor rails (40, 42, 44, 46) are preferably arranged at one or both face sides of the stator of the electric machine below the slot openings, i.e., in the area of the back of the stator.
