Claim 18:
19. A stator for an electric machine provided for purely electrically driving a motor vehicle, comprising:
a stator body forming a plurality of stator grooves,
a stator winding through which current can flow, which engages a respective stator groove of the plurality of stator grooves 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 a surface of the insulation paper for providing a higher creepage resistance compared to the surface of the insulation paper without the additional layer, and
wherein the additional layer covers an axial end of the insulation paper.
