Abstract

La présente invention se rapporte aux machines électriques à refroidissement cryogénique. La machine électrique à refroidissement cryogénique comporte en enroulement 9 d'excitation supraconducteur fixé dans un rotor creux 1 sur l'arbre 2 du rotor 1, ledit rotor étant rempli par un agent frigorifique 11. Le rotor 1 est entouré par un thermoécran électrique 10. Pour supprimer les apports de chaleur à l'enroulement d'excitation supraconducteur 9 par l'arbre 2 du rotor 1, sur ledit arbre 2, aux extrémités du rotor 1 sont montés des échangeurs de chaleur 17. L'invention est utilisee dans les machines électriques à refroidissement cryogénique.
