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.
