ABSTRACT:
The electric rotating machine has a stator and a rotor with superconducting windings placed within separate cryogenic enclosures for the stator and the rotor. The cryogenic enclosures are in turn placed within evacuated thermal insulation enclosures separated by the annular clearance space which is at low pressure, thus considerably simplifying the arrangements required for dynamic sealing of motor bearings.
