ABSTRACT:
The invention relates to an electric machine (2) comprising a rotor (6) that contains a shaft (18, 22) that is located, when in operation, in the ambient temperature range, and a superconducting rotor winding (30) that is cooled to a cryogenic temperature when in operation and which is arranged on the shaft (18, 22). Said machine also comprises a cooling system (8) for cooling the rotor winding (30), said system comprises a compensation pressure reservoir (50, 64) for a cooling medium (42). In said electric machine, the compensation pressure reservoir (50, 64) is arranged on the shaft (18, 22).
