Claim 15:
16. A method for an electric motor assembly, comprising:
during circulation of coolant via a stator and a rotor of an electric motor, activating a scavenge pump fluidly coupled to a radial air gap encapsulated by each of a ring and a sealing plate, to remove coolant from the radial air gap between the stator and the rotor via fluid channels housed within an interior of a rotor shaft, wherein the radial air gap is fluidly coupled to each of a first conduit formed between the ring and a first balancing plate of the rotor, and a second conduit formed between the sealing plate and a second balancing plate of the rotor, and wherein coolant is routed from the radial air gap via each of the first conduit and the second conduit to a reservoir by the scavenge pump, the coolant flowing from each of the first conduit and the second conduit to the reservoir via the fluid channels housed within the interior of the rotor shaft.
