Abstract
A method of operating a high speed machine, wherein the method includes providing at least one heteropolar generator that includes a stator, a rotor, and at least one stationary superconducting field coil therein. The method also includes coupling at least one cryogenic refrigeration system to the at least one stationary superconducting field coil, wherein the at least one cryogenic refrigeration system is coupled in flow communication with only the at least one stationary superconducting field coils to facilitate reducing an operating temperature of the at least one stationary superconducting field coil.
