ROTOR FOR AN ELECTRIC MACHINE

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.
