In der Patentschrift 162412 ist ein Verfahren angegeben, wonach die bei Einphasenkommutatormaschinen zum Anlassen benutzte Hilfswicklung auch während des normalen Betriebes vorteilhaft ausgenutzt werden kann. An Stelle des in jener Patentschrift vorgeschlagenen Mittels, des Stromwechsels in einer der beiden Hilfswicklungen, kann auch die Schaltung der beiden Hilfswicklungen in anderer Weise geändert werden, z. B. gemäß der vorliegenden, nachstehend beschriebenen und in der Zeichnung dargestellten Erfindung.In patent 162412 is a method specified, according to which the auxiliary winding used in single-phase commutator machines for starting also during normal Operation can be used to advantage. Instead of the one suggested in that patent specification By means of the current change in one of the two auxiliary windings, the connection of the two auxiliary windings in changed in other ways, e.g. According to the present, described below and the invention shown in the drawing.
In der Zeichnung ist die HauptwicklungIn the drawing is the main winding
mit a, die beiden Hilfswicklungen mit b und c bezeichnet. Mittels eines Schalters d werden nun während der Anlaßperiode, also solange der Motor als Repulsionsmotor läuft, die beiden Hilfswicklungen b und c behufs Verschiebung des resultierenden Feldes in Reihe geschaltet, so daß die im Hauptpatent ausführlich beschriebene Verdrehung des Hauptfeldes eintritt.with a, the two auxiliary windings with b and c . By means of a switch d , the two auxiliary windings b and c are connected in series during the starting period, i.e. as long as the motor is running as a repulsion motor, so that the main field is rotated as described in detail in the main patent.
Für den eigentlichen Betrieb wird der Schalter d aus der voll gezeichneten Stellung in die punktiert gezeichnete Stellung umgelegt, so daß nun die Wicklungen b und c parallel geschaltet sind und ein resultierendes Feld erzeugen, welches dieselbe Richtung hat wie das Hauptfeld und dieses verstärkt.For the actual operation, the switch d is flipped from the fully drawn position to the dotted position, so that now the windings b and c are connected in parallel and generate a resulting field which has the same direction as the main field and amplifies it.
Da die Reihenschaltung der beiden Spu- 3C len b und c nur während des Anlassens besteht, können sie während der kurzen Anlaßperiode unbedenklich überlastet werden. Ihr Querschnitt kann also z. B. nur für die halbe Stärke des Betriebsstromes bemessen werden, 3; so daß die Spulen b c während des eigentlichen Betriebes, also während der Parallelschaltung, voll ausgenutzt werden.Since the series circuit of the two SPU 3C len b and c only during the annealing is, they can safely be overloaded during the brief start period. Your cross-section can be, for. B. only be dimensioned for half the strength of the operating current, 3; so that the coils bc are fully utilized during the actual operation, that is, during the parallel connection.
In dem gezeichneten Beispiel wird der Motor nach dem Anlassen in bekannter Weise 4« in einen kompensierten Serienmotor umgeschaltet. Das Einschalten des Kollektors kann, wie ersichtlich, gleichfalls durch den gezeichneten Schalter d erfolgen, mittels dessen die Hilfswicklungen umgeschaltet werden. 4,In the example shown, the engine is switched to a compensated series engine in a known manner after starting. As can be seen, the collector can also be switched on by means of the switch d shown , by means of which the auxiliary windings are switched. 4,
