Abstract
L'invention concerne les machines électriques à refroidissement cryogénique. Cette machine comprend un enroulement d'excitation supraconducteur 9 placé dans un rotor creux 1 qui est entouré par un écran magnétique 12 est placé à l'intérieur de l'écran thermique dans lequel sont pratiqués des canaux de circulation de l'agent frigorifique 13 assurant le refroidissement de l'écran magnétique. L'écran thermique et l'écran magnétique 12 sont placés dans une cavité sous vide ménagée entre le rotor 1 et un corps 5. L'invention peut trouver des applications dans les machines électriques telles que les moteurs, générateurs, convertisseurs utilisées dans les centrales atomiques, thermiques et autres ainsi que dans les moyens de transport et dans l'aviation.
