Abstract

A stator for an electric machine includes: a laminated stator core including stator grooves and having a plug-in side and a bending side, which bending side lies opposite the plug-in side in an axial direction; a stator winding having hairpin elements which are pushed into the stator grooves on the plug-in side of the laminated stator core and bent and electrically connected to the stator winding on the bending side of the laminated stator core; and an end plate which is arranged on the plug-in side in the axial direction between the laminated stator core and the hairpin elements. The hairpin elements are arranged in the axial direction so as to bear against the end plate.
