Abstract

An electric machine has a plurality of phases. A winding is associated with each phase. An interconnection arrangement includes an annular carrier element with a plurality of axial cutouts, each for passage of a portion of a winding and a plurality of concentrically arranged, hollow-cylindrical switching rings. Each switching ring is adapted to contact a winding. The carrier element and the switching rings are adapted to radially positively engage one inside the other in an axial contact zone.
