    摘要: In a rotating machine, for example heteropolar, auxiliary poles (14) are placed in practically the field poles (4) and close to the peripheral of a salient section (.delta.) of rotor (2), the same azimuth symmetry plane as the poles are supplied by a current (i) regulated by a power supply and auxiliary regulation device (16), the armature current (I) and rotation speed (N) of the rotor expose armature conductors (8) in commutation to an equalizing flux providing for arc-free commutation. Auxiliary poles can be supplied with a current regulated by the field current to cancel the currents flowing in the armature conductors on the field poles. These machines, for example also acyclic with voltage step-up, have high specific power and efficiency, and can be employed for example, in electric traction or propulsion.

    摘要: 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.

    摘要: A linear motor comprises an electrically conductive tubular track consisting of one or more pairs of helically wound strips and a movable assembly. The movable assembly includes a superconducting field winding freely spinning about an axis close to the axis of the track and at least one auxiliary polyphase winding of normally conducting material coaxial to the field winding and adapted to develop a rotating field when AC currents circulate therein. The auxiliary winding supporting structure is connected to a vehicle to be driven along the track.

    摘要: 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.
