Rotary converter machine for direct transfer of electric energy by flux linkage between windings on a stator pack
First Claim
1. A rotary converter machine comprising a stator with a three-phase primary winding and a three-phase secondary winding as well as a rotor being provided with a damping winding and rotatably mounted in the stator, said rotor being provided with a d.c. exciting coil, said primary winding and said secondary winding being arranged on a common stator pack and located in continuous slots in the stator, each of the two windings extending over the whole axial length of said common stator pack.

Abstract
A rotary converter machine which includes a stator with three-phase primary, and secondary windings, and a rotor mounted within the stator which includes a damping winding. The primary and secondary stator windings are arranged on a common stator pack and located in continuous stator slots, both windings extending over the whole axial length of the common stator pack. The converter machine provides a direct transfer of the electrical energy by flux linkage between the two windings. The rotor is driven by the rotating magnetic field either asynchronously, if a drum rotor is provided, or synchronously, if a salient-pole rotor is provided.
