1. A stator for an electric machine comprising:
a stator core including a plurality of teeth defining a plurality of slots in the stator core; and
a winding positioned on the stator core, the winding comprising a plurality of segmented conductors connected together to provide a plurality of parallel paths per phase for the winding, each conductor comprising (i) an end loop provided on a crown end of the stator core, (ii) two legs extending through the slots of the stator core, and (iii) two leg ends extending out of the slots on a connection end of the stator core, each leg end having a twist portion;
wherein the winding defines a number of poles, a number of parallel paths per phase, a number of layers in each of the plurality of slots, and a number of pole-turns per parallel path, wherein the number of pole-turns per parallel path is not evenly divisible by the number of poles.
