ABSTRACT:
A reluctance-type machine arrangement includes a stator with salient poles and a rotor with salient poles surrounded by the stator, the number of stator poles being twice as great as the number of rotor poles. The stator is provided with a working winding and a first magnetizing winding connected to a constant voltage source. Each of the windings includes a number of two-pole coils each of which surrounds two stator poles located immediately one after the other in a peripheral direction. The two-pole coils of the first magnetizing winding are displaced by a stator pole pitch with respect to the two-pole coils of the working winding. A second magnetizing winding is provided which drives the flux along the same flux path and with substantially the same distribution between the various flux paths as the flux driven by the first magnetizing winding. The second magnetizing winding is series-connected to at least a part of the working winding by controlled rectifiers. The arrangement is such that the polarity of the magnetomotive force of the second magnetizing winding is unaltered during varying polarities of the working winding.
