Abstract
A stator for an electric machine provided for purely electrically driving a motor vehicle is provided with a stator body forming stator grooves, a stator winding through which current can flow, which engages in the respective stator groove and axially protrudes from the stator groove, for forming an electromagnetic rotating field and an insulation paper, which is provided in the stator groove between the stator winding and the stator body, for electrically insulating the stator winding from the stator body, wherein the insulation paper protrudes from the stator groove, wherein the insulation paper is provided with an additional layer on the surface thereof for providing a higher creepage resistance compared to the surface of the insulation paper without the additional layer.
