Abstract

L'invention concerne une machine électrique tournante, telle que dynamo ou alternateur, à rotor supraconducteur. Un organe de blindage cylindrique 14 protège le bobinage supraconducteur 5 de l'effet magnétique du stator et de la chaleur rayonnée à partir de la région non refroidie de la machine, afin que subsiste la supraconduction du bobinage 5 maintenu à température extrêmement basse. L'organe de blindage 14 est flanqué intérieurement et extérieurement de cylindres de renforcement 15A et 15B. Ceux-ci réduisent les efforts engendrés en service par la force centrifuge et par la force électromagnétique dans l'organe de blindage pour éviter que celui-ci ne se deforme ou ne se rompe. Applications courantes.
