Abstract
Disclosed is a rotor for a fluid cooled electric machine including a rotor shaft rotably located at a central axis and a plurality of rotating coolant passages extending outwardly from the rotor shaft to direct a flow of coolant to a desired impingement location on the electric machine thereby removing thermal energy from the impingement location. Further disclosed is a fluid cooled electric machine including a plurality of coolant passages each including at least one coolant passage inlet and at least one coolant passage outlet, the plurality of coolant passages configured to rotate about the central axis and direct a flow of coolant therethrough to a desired impingement location thereby removing thermal energy from the impingement location.
