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 interconnect a slot section of the associated winding conductor in the first layer and a slot section of the associated winding conductor in the second layer, wherein a first slot section is arranged in a first slot in a first radial position, and a second slot section, which is directly connected to the first slot section by a first end section, is arranged in a second slot in a second radial position which is offset by two radial positions in relation to the first radial position.
