Mit andern Worten : In Fig. 5 der genannten französischen Patentschrift handelt es sich um eine kompoundierte Maschine, während es sich hier um einen Motor handelt, der sich beim Anlaufen zunächst wie ein Serienmotor, im Betrieb dagegen vollständig wie ein Nebenschlussmotor verhält. Insoferne unterscheidet sich die vorliegende Einrichtung auch von derjenigen, wie sie durch E. T. Z. 04, S, 81, Fig. 63 bekannt geworden ist, bei welcher auch eine Doppelschlussschaltung zur Anwendung kommt.
Das Anlassen von gewöhnlichen kompensierten Nebenschlussmotoren als Serienmotoren ist im allgemeinen bekannt. Die vorliegende Einrichtung unterscheidet sich hiervon vor- teilhalft dadurch, dass der Übergang von einer Schaltung zu der anderen ohne Stromunterbrechung im Hauptstromkreis erfolgt und dass ausserdem, wie bereits erwähnt, der Erregertransformator stets nur die Differenz des Arbeitsstromes und des durch dil'Kommutator- spannung bestimmte Erregerstromes zu liefern hat und somit sehr klein sein kann.

In other words: FIG. 5 of the French patent mentioned is a compounded machine, while this is a motor which, when started, initially behaves like a series motor, while in operation it behaves completely like a shunt motor. In this respect, the present device also differs from that which has become known from E. T. Z. 04, S, 81, Fig. 63, in which a double-ended circuit is also used.
The starting of ordinary compensated shunt motors as series motors is generally known. The present device differs from this advantageously in that the transition from one circuit to the other takes place without current interruption in the main circuit and, in addition, as already mentioned, the excitation transformer always only determines the difference between the working current and the voltage through the commutator Has to deliver excitation current and can therefore be very small.
