Description
Der Erfindung liegt die Aufgabe zugrunde, beim Anlassen von Gleichstrommotoren durch unmittelbares Anschalten ans Netz unter Verwendung einer während des Anlaufs zu regelnden Anlaßverbundwicklung den bei Überbrückung der Anlaßwicklüng unter Umständen ' auftretenden starken Stromstoß zu vermeiden, ohne daß die Nebenschlußwicklung erst während des Anlaufs des Motors erregt wird. Die Aufgäbe wird wesentlich dadurch gelöst, daß die Wirkung der Hauptstromwicklung nicht völligThe invention is based on the object during starting of DC motors by immediately turning on the grid using a to avoid during start-up to be controlled occasion composite winding the 'occurring in bridging the Anlaßwicklüng may strong current surge without the shunt winding energized only during start-up of the motor will. The task is essentially achieved in that the effect of the main current winding is not completely
' aufgehoben, sondern nur erheblich verringert wird. Das Verfahren läßt sich in verschiedener Weise ausführen, so durch eine Teilung der Hauptstromwicklung und Überbrücken des einen Teils während des Anlaufs durch einen zwischen den beiden Teilwicklungen angeschlossenen Schalter, durch einen Kurzschluß oder Widerstand beliebiger Art, oder durch Schalten der auf den einzelnen Polen sitzenden Teilspulen der Hauptstromwicklung beim Anlegen ans Netz ganz oder teilweise in Reihe und während des Anlaufs ganz oder teilweise nebeneinander.'is repealed, but only significantly reduced. The procedure can be in different Execute way, so by dividing the main current winding and bridging the one Partly during start-up by a connected between the two partial windings Switch, by a short circuit or resistance of any kind, or by switching the partial coils of the main current winding that are seated on the individual poles when connected to the network, either completely or partially in series and completely or during start-up partly next to each other.
DieZeichnung stellt schematisch verschiedene Schaltmöglichkeiten dar.The drawing shows schematically various switching options.
In Fig. ι ist HW und AW eine aus zwei Teilen bestehende Hauptschlußwicklung, bei welcher der Schalter S an eine Anzapfung zwischen beiden Teilen angeschlossen ist. Durch den Schalter S wird während des Anlaufes der Widerstand W dem Teil AW nebengeschaltet. In Fig. Ι HW and AW is a main circuit consisting of two parts, in which the switch S is connected to a tap between the two parts. By means of the switch S, the resistor W is switched alongside the part AW during start-up.
Fig. 2 stellt dieselbe Schaltung dar wie Fig. i, mit dem Unterschied, daß' die Wick-■ . lung AW nicht durch den Widerstand W, sondern durch den Kürzschluß K überbrückt ist.Fig. 2 shows the same circuit as Fig. I, with the difference that 'the Wick- ■. ment AW is not bridged by the resistor W, but by the short circuit K.
In' Fig. 3 ist die Anlaßhauptstromwicklung in die einzelnen auf den Polen sitzenden Spulen unterteilt, beispielsweise in vier, welche beim Einschalten alle in Reihe liegen, während des Anlaufes aber nach Fig. 4 sämtlich nebeneinander geschaltet werden. Eine teilweise Reihen und Nebeneinanderschaltung ergibt sich aus Fig. 4 und 5 von selbst.In 'Fig. 3 is the starting main current winding in the individual coils seated on the poles divided, for example into four, which are all in series when switched on, during the Start-up but according to Fig. 4 are all switched side by side. A partial rows and Side-by-side connection is evident from FIGS. 4 and 5 by itself.
