Description
KAISERLICHES
PATENTAMT.
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 das
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.
In der Zeichnung ist die Schaltung in Fig. ι dargestellt.
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.
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.
Die Wirkungsweise ist die folgende:
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. Aus
ihr geht hervor, daß im letzteren Falle die Geschwindigkeit weniger stark abfällt.

- Patent-Anspruch:Schaltung für einen Elektromotor mit gemischter Wicklung und mit ihm gekuppelter Zusatzmaschine, deren Anker hinter die Nebenschlußwicklung des Motors geschaltet ist, dadurch gekennzeichnet, daß der Feldmagnet der Zusatzmaschine von dem Hauptstrom des Motors durchflossen wird.Hierzu ι Blatt Zeichnungen.
