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.

Abstract: A device for twisting hairpin ends of a coil formed from hairpins for an electric machine includes: a plurality of coaxially arranged twisting rings having: two outer twisting rings and, therebetween, at least at least two inner twisting rings. The twisting rings have, in each instance, at an axial end facing hairpin ends, a plurality of pockets distributed over a circumference for receiving a hairpin end, respectively. The twisting rings are twistable in opposite directions relative to one another, the twisting rings having couplings by which twisting rings with like rotational direction are connectable.
