1. A rotor comprising:
- a rotor body defining pole faces and having parallel sides perpendicular to said pole faces;
a flat field winding slideable over parallel sides of a rotor body of said electric machine and angled at an end turn, wherein the flat field winding comprises straight portion extending over the parallel sides of the rotor body, wherein a vertex of said flat field winding is aligned with an axis of rotation, said vertex providing a predetermined axial offset so as to compensate for a radial expansion of said flat field winding when disposed to a centrifugal force.

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.
