KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, daß man eine Tourenregelung von Mehrphasen-Kollektormaschinen sowie eine Verbesserung ihres Leistungsfaktors dadurch erreichen kann, daß man parallel zum Läufer Drosselspulen schaltet (Patent 177255). Nach vorliegender Erfindung werden die Drosselspulen ganz oder teilweise dadurch vermieden, daß man parallel zum Läufer unmittelbar oder mittelbar, z. B. mittels Transformatoren mit veränderlicher Übersetzung, die Feldwicklung legt. Unter Feldwicklung ist hier diejenige Wicklung zu verstehen, in der wesentlich nur wattloser Strom fließt. Außer dieser Wicklung muß daher auf dem Ständer noch eine mit dem Läufer in Serie liegende Kompensationswicklung vorhanden sein.It is known that a tour control of multi-phase collector machines as well an improvement in their power factor can be achieved by running parallel to the Rotor switches choke coils (patent 177255). According to the present invention, the Choke coils wholly or partially avoided by running parallel to the rotor directly or indirectly, e.g. B. by means of transformers with variable translation that Field winding sets. The field winding is to be understood here as the winding in which essentially only wattless electricity flows. In addition to this winding must therefore be on the stand a compensation winding in series with the rotor may still be present.
In der Figur ist ein Ausführungsbeispiel dargestellt. Es bedeutet hier k die Kompensationswicklung und f die Feldwicklung, deren ao veränderliche Windungszahl an die Bürsten b angelegt ist.An exemplary embodiment is shown in the figure. Here, k means the compensation winding and f the field winding, whose ao variable number of turns is applied to the brushes b .
Im Stromkreis der Feldwicklung können noch Hilfsdrosselspulen verwendet werden, um zwecks Vermeidung der Funkenbildung und der feineren Einstellung des Leistungsfaktors und der Tourenzahl einen ganz reinen wattlosen Strom zu erhalten. Die Drosselspulen sind aber in diesem Falle wesentlich kleiner als bei der bisherigen Ausführung.Auxiliary reactors can also be used in the field winding circuit to avoid sparking and fine-tune the power factor and the number of tours to get a completely pure wattless electricity. The reactors but in this case are much smaller than in the previous version.
