Abstract
A group of three stator windings for a stator of an electric machine, a stator arrangement, a generator, and wind turbine are provided. The first winding head segments of the three stator windings differ in form such that the first winding head segments of at least two of the three stator windings are differently tilted in radial direction of the electric machine and the length of the three stator windings is substantially the same.

18. A group of three stator windings for a stator of an electric machine, wherein
the stator comprises a first cylindrical surface with a plurality circumferentially spaced winding slots, each winding slot extending along an axial length of the first cylindrical surface and formed to embed a segment of a single stator winding, each stator winding is pre-formed as a closed loop, two substantially parallel segments of each stator winding formed to be embedded in a first and a second winding slot of the stator, with the second winding slot being the third adjacent winding slot to the first winding slot, each of the three stator windings comprising a first winding head segment extending from the winding slots in axial direction of the stator, the first winding head segments of the three stator windings differ in form so that the first winding head segments of at least two of the three stator windings are differently tilted in radial direction of the electric machine, and the length of the three stator windings is substantially the same.
