Abstract

A stator for an electric machine, comprising a stator core and a stator winding, wherein the stator core has a plurality of slots, which are spaced apart in a circumferential direction and have a depth running in the radial direction, and allows the arrangement of slot sections of the stator winding in a plurality of radially spaced-apart radial positions, wherein the stator has a strip-like winding unit comprising a first and a second winding conductor, wherein the two winding conductors run in a first and a second layer of the winding unit and each comprises:a plurality of straight slot sections which run in a transverse direction of the winding unit and are arranged in parallel,a plurality of first bent end sections which each interconnect two slot sections of the associated winding conductor and are arranged on a first longitudinal side of the winding unit,a plurality of second bent end sections which each interconnect two slot sections of the associated winding conductor and are arranged on a second longitudinal side of the winding unit, which second longitudinal side is situated opposite the first longitudinal side, wherein,the first and the second bent end sections each inte…
