Abstract
A winding module for an electric machine is provided wherein the winding module comprises a flat field winding that is angled at an end turn and wherein a vertex of the flat field winding is aligned with an axis of rotation. The vertex provides a predetermined axial offset so as to compensate for a radial expansion of the flat field winding when it is disposed to a centrifugal force.
