Abstract

La présente invention se rapporte aux machines électriques à refroidissement cryogénique. La machine suivant l'invention comprend un enroulement d'excitation supraconducteur 8 fixé dans la cavité du rotor 1 sur son arbre 2. La cavité du rotor 1 est remplie d'un agent frigorifique 10. A une extrémité de l'arbre 2 du rotor 1 est réalisé un conduit axial 17 d'amenée de l'agent frigorifique 10. A l'autre extrémité de l'arbre 2 est réalisé un conduit axial 18 d'évacuation de l'agent frigorifique 10. Dans l'arbre 2 du rotor 1, dans les zones de fixation de l'enroulement d'excitation supraconducteur sont réalisées des encoches 12 qui communiquent avec le conduit axial 17, et aussi avec le conduit axial 18. Aux deux extrémités de l'arbre 2 sont réalisés des conduits 16 d'évacuation de l'agent frigorifique 10 qui communiquent avec la cavité du rotor 1.
