  Einrichtung zur Regelung von   Wech8eI8trom-Kommutatorma8chinen.   



   Nach dem   österr.   Patent Nr. 30701 werden Wechselstrom-Kommutatormaschinen mit Kurzschluss- und Erregerbürsten während des Anlaufs dadurch erregt, dass die Erregerströme dem Anker durch die Kurzschlussverbindungen (bezw. eine der   Kurzschlussverbindungen)   zugeführt und durch einen Teil der   Erregerbürsten   abgeleitet werden. Nach vorliegender Erfindung wird dann für dio Schaltung als   Nebenschlussmaschine   nicht, wie bekannt, die   Kurzschlussverbindung   an einen bestimmten Teilpunkt der Netzspannung gelegt (Fig. 1), vielmehr wird die   Anlass (Reiben-) schaltung   unverändert gelassen und die   Nebenschluss-   erregung durch die zwei   Erregerbürsten   hervorgerufen (Fig. 2).

   Es überlagern sich auf diese Weise im Anker der Arbeitsstrom, der Reibenerregerstrom und der Nebenschlusserregerstrom. 



   In den Figuren bedeutet s die Ständerwicklung, k die Kurzschlussbürstenverbindung, e die Erregerbürsten, t einen regelbaren Transformator, durch welchen die dem Motor zugeführte Spannung geregelt werden kann. Der Schalter a ist im Anlauf offen und wird später geschlossen. Die Schliessung kann auch   selbsttätig in   Abhängigkeit von der Umlaufszahl des Motors oder durch ein Relais in Abhängigkeit von einer der vorhandenen Spannungen erfolgen. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Device for the regulation of AC commutator machines.



   According to Austrian Patent No. 30701, AC commutator machines with short-circuit and exciter brushes are excited during start-up by the excitation currents being fed to the armature through the short-circuit connections (or one of the short-circuit connections) and diverted through some of the exciter brushes. According to the present invention, for the circuit as a shunt machine, the short-circuit connection is not, as is known, placed at a certain point in the mains voltage (Fig. 1), but rather the starting (friction) circuit is left unchanged and the shunt excitation by the two exciter brushes caused (Fig. 2).

   In this way, the working current, the friction excitation current and the shunt excitation current are superimposed in the armature.



   In the figures, s denotes the stator winding, k the short-circuit brush connection, e the exciter brushes, t a controllable transformer through which the voltage supplied to the motor can be regulated. Switch a is open at startup and is closed later. The closing can also take place automatically depending on the number of revolutions of the motor or by a relay depending on one of the voltages available.
