1. A motor comprising:
a stator assembly; and
a rotor assembly configured to be rotatable relative to the stator assembly,
wherein the stator assembly comprises:
a stator core having stator slots; and
electrical conductors at least partially disposed in the stator slots, the electrical conductors having a plurality of hairpin winding segments,
each of the hairpin winding segments comprising:
first and second legs, each of the first and second legs having an in-slot portion disposed in one of the stator slots, and
an endturn portion formed between the first and second legs,
wherein a thickness of the endturn portion formed between the first and second legs of each of the hairpin winding segments is different from a thickness of the in-slot portion of the first and second legs of each of the hairpin winding segments, disposed in one of the stator slots.
