Title: Polyphase synchronous electrical machine with superconductor winding

Abstract: The machine comprises a rotary assembly comprising a hollow shaft containing the inductor, a passive screen for protecting the inductor against rapid variations in field due to disturbances in the armature. An auxiliary winding borne by the shaft creates a rotary magnetic field of intensity and frequency such that it completes the compensation of the magnetic fields created by the armature. The machine is useful for synchronous power alternators.
