SUPER CONDUCTING SYNCHRONOUS MACHINE COMPRISING A ROTOR WHICH CAN ROTATE IN RELATION TO A STATOR AND WHICH HAS AT LEAST ONE SUPER CONDUCTING WINDING

摘要

A super conducting synchronous machine including a rotor which may rotate in relation to a stator and which has at least one super-conducting winding which is cooled my means of a cooling machine is provided. The cooled areas of the rotor are surrounded at least partially by a vacuum chamber rotating with the rotor. A pump line connecting the vacuum chamber to a vacuum pump is provided in a connection area produced by means of at least two rotational seals, fixed in relation to a rotor and defining the vacuum chamber.
