ABSTRACT:
A synchronous rotary electric machine has a stationary superconducting D.C. field winding, a rotatable mechanical torque transmission shaft which carries normally conducting polyphase windings for providing a rotating field when A.C. currents circulate therein, and stationary auxiliary D.C. windings constructed to deliver a magnetic field. The currents in the auxiliary windings are adjusted for maintaining the torque and axial force tending to move the field winding under a predetermined value.
