ABSTRACT:
A cooling arrangement for the rotor of an electric machine having a superconducting field winding and a co-rotating mixing chamber containing a phase mixture of a coolant has a coolant distribution system arranged at the outer circumference of the field winding which feeds coolant into cooling canals through the field winding into the mixing chamber. There are also corresponding coolant connecting lines outside the winding, at least one coolant feed line connected to the coolant distribution system for supplying coolant from the outside, and a discharge for the gaseous coolant at a pressure below 10.sup.5 Pa. In this cooling arrangement, cooling of the field winding is advantageously brought about by self-pumping. Simple and effective cooling-down is achieved.
