Abstract: A rotor for an electric machine includes: a rotor body; winding elements; and a winding head, which includes a winding head support and retaining elements, each of which includes a tension bolt and a support body, wherein the support bodies are arranged at least partially in a radial direction outside of the winding elements, wherein the tension bolt penetrates the support body associated therewith and is screwed into the winding head support by a thread, wherein each of the retaining elements includes a stop surface for coming into contact with the winding head support when screwing in the tension bolts in order thereby to adjust a radial length with which the tension bolts protrude from the winding head support to a predefined dimension, and wherein the predefined dimension is calculated so that the support bodies are not pressed against the winding elements in a resting position of the rotor.

Abstract: A rotor for an electric machine includes a rotor body, winding elements, and a winding head arranged axially adjacent to the rotor body, and wherein the winding head encompasses two regions, wherein in a first region the winding elements progress in axial direction, and wherein in a second region the winding elements progress at an angle to the axial direction, and wherein each winding element in the second region in which it progresses at an angle to the axial direction is located at a distance of A1 from a first directly adjacent winding element of the same layer and at a distance A2 from a second directly adjacent winding element of the same layer, wherein A2 is greater than A1.

Abstract: A rotor for an electric machine has winding elements which are arranged in axially running grooves of a rotor body and having a winding head which is arranged axially next to the rotor body. The winding elements exit from the grooves in the axial direction in the region of the winding head and run in the axial direction in the region of the axial ends of the winding elements. Each of the winding elements has four curved portions in the region of the winding head. The rotor includes a plurality of tension bolts and a winding head carrier. The tension bolts connect the winding head to the winding head carrier and penetrate through the winding head radially.
