Methods and systems are provided to cool an electric machine. In one embodiment, an electric machine includes a rotor assembly that includes a rotor shaft and a stack of rotor laminations. The rotor assembly further includes one or more nozzles designed to receive pressurized coolant from a rotor shaft coolant passage and deliver the coolant to a set of open coolant channels in the stack of rotor laminations, wherein the set open coolant channels includes outlets that are profiled to direct the coolant towards a groove in a balancing plate that is coupled to the rotor assembly.
