Abstract
A rotor for an electric machine is described, wherein the rotor comprises a base body extending along a longitudinal axis from a first end face to an opposite second end face. The rotor further comprises at least one groove arranged in the base body, extending along the longitudinal axis from the first end face to the second end face of the base body, the groove being bounded by a contact surface, and a layered groove insulation arranged on the contact surface of the groove. The rotor also comprises an electrically conductive winding arranged in the groove, which contacts the groove insulation. The groove insulation is designed to expand permanently in response to the action of thermal energy and / or a chemical substance, such that the winding is moved away from the contact surface as a result of the expansion of the groove insulation.
