Patent
·
OSTI ID:7287372
The invention relates to a coolant circuit for the rotor of an electric machine, such as a turbogenerator, especially, having a superconductive excitation winding. More specifically, the invention relates to such a coolant circuit which includes a cold shield with a damping winding surrounding the superconductive excitation winding, as well as a coolant connecting head which surrounds the rotor shaft end located at the excitation-winding side and through which coolant flowing from a refrigerating machine or cryostat is fed to an axial bore formed in the rotor shaft and again discharged from the shaft through a collection chamber surrounding the shaft.
