Abstract: An electrical machine of a vehicle electrical propulsion system includes a stator, a rotor, and a stator winding all disposed within a housing thereof. The stator defines a central bore elongated along a longitudinal axis, and multiple slots circumferentially disposed around the central bore. The rotor is held within the central bore and rotates relative to the stator. The stator winding includes a core conductor, an insulation layer surrounding the core conductor, and a conductive shield layer surrounding the insulation layer. The stator winding extends through the slots of the stator. The stator winding includes an in-slot portion within the slots of the stator and an end-winding portion outside of the slots. The conductive shield layer surrounds the insulation layer along both the in-slot portion and the end-winding portion of the stator winding.
