ABSTRACT:
The invention relates to an arrangement for cooling the rotor of an electric machine, especially a turbine-type generator. The rotor contains a superconducting field winding, a co-rotating cold shield and a co-rotating mixing chamber for receiving a phase mixture of a coolant. A first coolant stream with a liquid coolant is further provided for cooling the field winding and a second coolant stream for cooling the cold shield. A substream derived from the first coolant stream after the latter has passed through the field winding is admixed to the second coolant stream and that a corresponding connecting line is provided with a throttling device.
