Abstract: A motor comprises: 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 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. The endturn portion formed between the first and second legs is thicker than the in-slot portion of the first and second legs, disposed in the stator slot. Further, thicknesses of open end portions formed at ends of the first and second legs are different from a thickness of the in-slot portion of the first and second legs, disposed in the stator slot.
