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

The invention relates to a super conducting synchronous machine (1, 1', 1'', 1' ' ') comprising a rotor (3) which can rotate in relation to a stator (2) and which has at least one super-conducting winding which is cooled my means of a cooling machine (5). The cooled areas of the rotor (3) are surrounded at least partially by a vacuum chamber (10) rotating with the rotor (3). A pump line (21) connecting the vacuum chamber (10) to a vacuum pump (23) is provided in a connection area (22) produced by means of at least two rotational seals (13a, 13b), fixed in relation to the rotor (3) and defining the vacuum chamber (10).
