Abstract
A cooling device for a superconducting field winding of an electric machine, especially a turbo-generator, contains an exhaust gas line connected to a coolant space for cooling an end piece at the end face of a torque transmitting rotor body part as well as a coolant line extending along a damper shield arranged around the field winding. In order to utilize the liquid coolant in a particularly economical and simple manner, the coolant line of the damper shield is a section of the coolant exhaust gas line, and this section is arranged, as seen in the flow direction of the coolant exhaust gas, ahead of the line section of the torque transmitting end piece.
