少なくとも１つの超電導巻線を備え固定子に対し回転可能な回転子を有する超電導同期機

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.
