1. A stator for an electric machine comprising:
a stator core including a plurality of teeth defining a plurality of slots, the stator core having a first axial end and a second axial end opposite the first axial end; and
a winding positioned on the stator core, the winding comprising a plurality of parallel paths per phase for the winding, each parallel path comprising (i) a plurality of first end loops provided on the first axial end of the stator core, (ii) a plurality of conductors extending through the slots, and (iii) a plurality of second end loops provided on the second axial end of the stator core;
wherein the plurality of conductors are arranged in layers in the slots, wherein the layers include a total number of layers (L) including at least two inner layers, two middle layers, and at least two outer layers, wherein L/2 is an odd whole number; and
wherein the winding defines a common pitch (CP), and wherein the first end loops and second end loops associated with the middle layers alternate between having a pitch equal to CP+1 on the first axial end and a pitch equal to CP−1 on the second axial end.
