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.
