Abstract: A dual axial cooling system for an electric motor includes a cover assembly provided at first and second axial ends of a stator of the electric motor. Each cover assembly includes a first side portion that is oriented so as to face an interior of the stator, with a plurality of holes formed in the first side portion. A second side portion is coupled to the first side portion, so that a passage is formed between the first and second side portions. A supply nozzle portion is in fluid communication with the plurality of openings via the passage defined between the first and second side portions. The plurality of openings receive cooling fluid from the supply nozzle portion, and discharge the cooling fluid in an axial direction, from each axial end portion of the stator, to provide axial cooling in two axial directions into the stator.

Abstract: A vehicle may include a plurality of separate and distinct electrical busbars that are electrically isolated from each other. A device may include a polymer overmold material that mechanically couples the separate and distinct electrical busbars to each other in a single integrated multi-busbar unit, wherein the overmold material is provided to the busbars through an injection molding process. A device may include a flex printed circuit board having a plurality of sensors that is coupled to the single integrated multi-busbar unit, wherein the sensors are coupled to the distinct electrical busbars when the flex printed circuit board is coupled to the integrated busbar unit.
