KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Um bei Motoren mit wechselnder Belastung den Arbeitsgang zu regeln, benutzt man Schwungräder, wobei das Schwungrad als Speicher für die Energie wirkt. Im Falle von Gleichstrommotoren mit gemischter Wicklung bewirkt ein geringer Abfall der Geschwindigkeit, wie bekannt, bereits eine beträchtliche Belastung des Motors. Bei auftretenden Belastungen ist es zuerst dasUsed to regulate the operation of motors with changing loads one flywheels, whereby the flywheel acts as a store for the energy. In the case of DC motors with mixed Winding causes a slight drop in speed, as is known, already a considerable load on the engine. When stress occurs, it is that first
ίο Schwungrad, welches den Hauptteil der Arbeit abgibt, alsdann nach Abfall der Geschwindigkeit der Elektromotor, welcher durch Ansteigen des Stromes in der Hauptwicklung an der Arbeitsabgabe mehr teilnimmt. Dem soll die Erfindung abhelfen, indem noch eine Zusatzmaschine, welche vom Hauptstrom erregt wird und je eine entgegengesetzt gewickelte Wicklung des Motors speist, angeordnet wird.ίο flywheel, which is the main part of the Gives up work, then, after the speed has dropped, the electric motor, which participates more in the work charge by increasing the current in the main winding. The invention is intended to remedy this by adding an additional machine, which is excited by the main current and one opposite each other wound winding of the motor feeds, is arranged.
In der Zeichnung ist die Schaltung in Fig. ι dargestellt.In the drawing, the circuit is shown in Fig. Ι.
Der Motor 2 mit der Hauptstromwicklung 6 ist mit der Zusatzmaschine 1 gekuppelt. Der Strom der genannten Hauptstromwicklung 6 durchfließt die Erregerspule 7 der Zusatzmaschine I. In diesen Stromkreis ist noch der Widerstand 9 eingeschaltet. Die Nebenschlußwicklung 8 ist an die Bürste 12 des Ankers II angeschlossen (die andere Bürste ist mit 13 bezeichnet) und der Strom geht über die Nebenschlußwicklung 8, welche mit der Wicklung 6 gleichsinnig gewickelt ist, den Anker 3 der Zusatzmaschine und den Widerstand 10. Dabei ist die elektromotorische Kraft der Zusatzmaschine der der Hauptstromquelle, welche die Leitungen 4 und 5 speist, entgegenwirkend. The motor 2 with the main current winding 6 is coupled to the auxiliary machine 1. The current of said main current winding 6 flows through the excitation coil 7 of the additional machine I. The resistor 9 is also switched on in this circuit. The shunt winding 8 is connected to the brush 12 of the armature II (the other brush is labeled 13) and the current goes through the shunt winding 8, which is wound in the same direction as the winding 6, the armature 3 of the Additional machine and the resistor 10. The electromotive force is the Additional machine that of the main power source, which feeds the lines 4 and 5, counteracting.
Ein Wachsen der Belastung hat einerseits ein Ansteigen des Stromes in 6 zur Folge, andererseits aber eine Abnahme der Stromstärke in Wicklung 8, welche bei gewöhnlichen Kompoundmotoren konstant erregt bleibt. Es wird also das Anwachsen des Stromes in 6 stets durch die Veränderung in 8 ganz oder teilweise kompensiert werden, wobei der Grad der Kompensierung von den Dimensionen der Wicklungen abhängt. On the one hand, an increase in the load results in an increase in the current in 6, on the other hand, however, a decrease in the amperage in winding 8, which in ordinary Compound motors remains constantly excited. The increase in the current in 6 will therefore always be due to the change can be fully or partially compensated in FIG. 8, the degree of compensation depending on the dimensions of the windings.
Die Wirkungsweise ist die folgende:The mode of action is as follows:
In Fig. 2 ist die Geschwindigkeit eines gewöhnlichen Kompoundmotors dargestellt und in Fig. 3 diejenige der neuen Einrichtung. Aus Vergleich beider ergibt sich, daß die gleiche Geschwindigkeitsänderung in Fig. 3 einer beträchtlicheren Belastung "für den Motor entspricht, als es der Fall für Fig. 2 ist. Ist die Geschwindigkeit um einen gewissen Wert geändert, so ist der Motor nach Fig. 3 fähig, eine beträchtlich größere ' Arbeit zu liefern als der nach Fig. 1. In Fig. 4 ist die Geschwindigkeitskurve des Schwungrades als Funktion der Zeit eingetragen , und zwar sowohl für einen gewöhnlichen Kompoundmotor als auch für die Anordnung nach der Erfindung. AusIn Fig. 2 the speed of an ordinary compound motor is shown and in Fig. 3 that of the new facility. A comparison of the two shows that the same speed change in Fig. 3 of a more considerable load "for corresponds to the engine than is the case for FIG. Is the speed around one If changed to a certain value, the motor according to FIG. 3 is capable of a considerably larger one 'To deliver work than that of Fig. 1. In Fig. 4 is the speed curve of the Flywheel entered as a function of time, both for an ordinary one Compound engine as well as for the arrangement according to the invention. the end
ihr geht hervor, daß im letzteren Falle die Geschwindigkeit weniger stark abfällt.you can see that in the latter case the speed drops less sharply.
