Abstract
A two-phased liquid-cooled AC rotating electrical includes a plurality of cooling circuits that recirculate and transition respective engineered liquids between liquid and vapor states around closed-loop fluid paths to cool a plurality of machine components e.g., hollow conductor rotor and stator windings and a magnetic stator core. A portion of each fluid path is either integrated with or in thermal contact with its component. The engineered liquids are evaporated within the respective portions of the fluid paths to hold the operating temperatures at or near the respective and different phase transition temperatures.
