Abstract
The invention relates to a bar winding arrangement of a stator or a rotor of an electric machine, including a number of bar segments, which are housed in a plurality of slots of the stator or the rotor and are electrically connected to one another in such a way that they form a continuous winding of the stator or the rotor, wherein each of the slots is divided by the bar segments into a first group of bar segments and at least one second group of bar segments, wherein the bar segments of the first group have a smaller cross section than the bar segments of the second group, wherein the bar segments of the first group are electrically connected in series and the bar segments of the second group are electrically connected in series and in parallel with the bar segments of the first group and wherein the bar segments of the first group are arranged closer to a slot opening in the radial direction than the bar segments of the second group.
