Abstract
A stator of an electric machine has an annular stator lamination stack at which stator coils with coil ends are arranged by winding bodies and are interconnected with an interconnection device that has a plurality of connection conductors arranged coaxially to one another and which are electrically insulated from one another by insulating layers. The connection conductors have coil connection regions for the coil ends and power connection regions for supplying power to the electric machine (). The connection conductors are annular disks and are arranged in an axially staggered manner at the stator. Each connection conductor has at least one fastening portion for fastening to the stator and a winding body has at least one connection area. The fastening portions of the connection conductors are arranged to overlap one another, and the connection conductors are fastened along with them to the connection area of the winding body.
