Rotating Electrical Machine with Superconducting Elements and Cryogenic Enclosures

Abstract : Disclosed is a rotating electrical machine with axial air gap, comprising two rotors, each provided with superconducting axial magnetic flux barrier elements around an axis of rotation and having, between them, axial magnetic flux passage areas, at least one armature, comprising windings and a superconducting field coil surrounding the elements and the armature and capable of inducing an axial magnetic field. Each armature is positioned between two of the rotors. The superconducting elements of the rotors are coaxial with one another and also the flux passage areas. A first annular cryogenic enclosure encloses the field coil and a second cryogenic enclosure encloses the two rotors and the armature or only one rotor, with a third cryogenic enclosure around the other rotor without the armature.
