Abstract
A cryogenic cooling system for use with a superconductive electric machine includes a first set of components arranged in a first circuit and adapted to force flow of a cryogen in the first circuit to and from a superconductive electric machine and being operable in a cooldown mode for cooling the cryogen and thereby the superconductive electric machine to a normal operating temperature, and a second set of components arranged in a second circuit and adapted to force flow of a cryogen in the second circuit to and from the superconductive electric machine and being operable in a normal mode for maintaining the cryogen and thereby the superconductive electric machine at the normal operating temperature.
