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 connected to an interconnection device arranged at the stator lamination stack on the front side. The interconnection device () is fixed to the stator coils by a carrier element and has connection conductors arranged coaxial to one another that are electrically insulated from one another by insulating layers and carried by the carrier element. Coil connection areas and power connection areas are provided at the connection conductors. The carrier element is formed by one of the connection conductors and/or by a disk-shaped insulating layer and that the connection conductors and the further insulating layers are fixed to the carrier element.
