The turbogenerator rotor has a superconducting excitation winding surrounded by a rotating cold screen. A rotating mixing chamber contains a phase mixture of an externally supplied coolant. It delivers a liq. coolant flow to the excitation winding, and a second flow with partly evaporated coolant for cooling the cold screen. Coolant from the winding is fed back to the mixer, and from the cold screen out of the machine. - A component flow (A2, B2) derived from the first coolant flow (A1) after its passage through the winding (5) is added to the second flow (B1). A corresponding connecting channel (24) with a throttle (26) is provided for lowering the pressure of the derived flow (A2).
