KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Um bei Motoren mit wechselnder Belastung den Arbeitsgang zu regeln, benutztman Schwungräder, wobei das Schwungrad als Speicher für die Energie wirkt. Im Falle von Gleichstrommotoren mit gemischterWicklung bewirkt ein geringer Abfall der Geschwindigkeit, wie bekannt, bereits einebeträchtliche Belastung des Motors. Bei auftretenden Belastungen ist es zuerst dasUsed to regulate the operation of motors with changing loadsone flywheels, whereby the flywheel acts as a store for the energy. In the case of DC motors with mixedWinding causes a slight drop in speed, as is known, already aconsiderable load on the engine. When stress occurs, it is that first

ίο Schwungrad, welches den Hauptteil derArbeit abgibt, alsdann nach Abfall der Geschwindigkeit der Elektromotor, welcherdurch 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 entgegengesetztgewickelte Wicklung des Motors speist, angeordnet wird.ίο flywheel, which is the main part of theGives up work, then, after the speed has dropped, the electric motor, whichparticipates 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 otherwound 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 Erregerspule7 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 Nebenschlußwicklung8, welche mit der Wicklung 6 gleichsinnig gewickelt ist, den Anker 3 derZusatzmaschine und den Widerstand 10. Dabei ist die elektromotorische Kraft derZusatzmaschine 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 coil7 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 winding8, which is wound in the same direction as the winding 6, the armature 3 of theAdditional machine and the resistor 10. The electromotive force is theAdditional 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 gewöhnlichenKompoundmotoren konstant erregt bleibt. Es wird also das Anwachsen des Stromes in 6 stets durch die Veränderungin 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 ordinaryCompound motors remains constantly excited. The increase in the current in 6 will therefore always be due to the changecan 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 dargestelltund in Fig. 3 diejenige der neuen Einrichtung. Aus Vergleich beider ergibt sich,daß die gleiche Geschwindigkeitsänderung in Fig. 3 einer beträchtlicheren Belastung "fürden Motor entspricht, als es der Fall für Fig. 2 ist. Ist die Geschwindigkeit um einengewissen 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 desSchwungrades als Funktion der Zeit eingetragen , und zwar sowohl für einen gewöhnlichenKompoundmotor als auch für die Anordnung nach der Erfindung. AusIn Fig. 2 the speed of an ordinary compound motor is shownand in Fig. 3 that of the new facility. A comparison of the two showsthat the same speed change in Fig. 3 of a more considerable load "forcorresponds to the engine than is the case for FIG. Is the speed around oneIf 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 theFlywheel entered as a function of time, both for an ordinary oneCompound 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.
