Description

Einrichtung zur Verhinderung des Pendelns von Motoren, die in der einen Drehrichtung mit Hauptschluß-, in der anderen Drehrichtung mit Nebenschlußcharakteristik arbeiten sollen. Nebenschlußmotoren mit schwachem Feld neigen zum Pendeln, insbesondere beim Anlassen oder beim Regeln auf eine höhere Drehzahl. Es ist bekannt, daß diese Unstabilität durch feldstärkende Zusatzreihenschlußwindungen beseitigt werden kann, wobei die Reihenschlußwicklung bei Motoren mit wechselnder Drehrichtung beim Umsteuern umgeschaltet werden muß, da sie sonst die Labilität verstärkt. Diese Motoren sollen vielfach in der einen Drehrichtung mit Hauptschluß- und in der anderen mit Nebenschlußcharakteristik arbeiten und sind dementsprechend mit einer Reihenschlußwicklung versehen, die jedoch beim Übergang vom Lauf mit Hauptschlußcharakteristik auf den in umgekehrter Drehrichtung mit Nebenschlußcharakteristik zum Verhüten des dabei auftretenden Pendelns nicht umgeschaltet werden kann, weil dann die hier erwünschte Nebenschlußcharakteristik verlorenginge.Device to prevent the oscillation of motors operating in the one direction of rotation with main circuit, in the other direction of rotation with shunt characteristic should work. Weak field shunt motors are prone to hunting, especially when starting or when adjusting to a higher speed. It is known that this Instability can be eliminated by field-strengthening additional series winding turns, the series winding in motors with alternating direction of rotation when reversing must be switched, otherwise it increases the instability. These engines are supposed to often in one direction of rotation with main circuit and in the other with shunt characteristic work and are accordingly provided with a series winding, but the at the transition from the barrel with the main closing characteristic to the one in the opposite direction of rotation with a shunt characteristic to prevent the oscillation that occurs can be switched because then the desired shunt characteristic would be lost.

Um solche Motoren auch beim Arbeiten mit reiner Nebenschlußcharakteristik vor dem Pendeln zu schützen, sind erfindungsgemäß außer der Nebenschlußwicklung zwei entgegengesetzt wirkende, verschieden starke Reihenschlußzusatzwicklungenvorgesehen. Die stärkere dient zur Hervorrufung der Hauptschlußcharalkteristik in -der einen Richtung, während die schwächere das Pendeln beim Lauf mit Nebenschlußcharakteristik in der anderen Drehrichtung verhüten soll.Around such motors even when working with pure shunt characteristics In accordance with the invention, apart from the shunt winding, are to be protected from oscillation two oppositely acting, different strength series connection additional windings provided. The stronger one serves to evoke the main conclusion characteristics in one Direction, while the weaker the oscillation when running with a shunt characteristic should prevent in the other direction of rotation.

Um das abwechselnde Aus- und Einschalten der beiden Reihenschlußwicklungen zu vermeiden, können sie vorteilhaft so angeordnet werden, daß die schwächere dauernd vom Ankerstrom durchflossen wird, während die stärkere beim Wechsel der Drehrichtung abgeschaltet oder kurzgeschlossen wird. Diese muß genügend stark sein, um beim Lauf mit Hauptschlußcharakteristik das durch die schwächere erzeugte, entgegengesetzt gerichtete Feld zu vernichten und dabei darüber hinaus dem Motor die gewünschte Reihenschlüßcharakteristik zu verleihen.About the alternating switching on and off of the two series windings To avoid this, they can advantageously be arranged so that the weaker one is permanent is traversed by the armature current, while the stronger when changing the direction of rotation switched off or short-circuited. This must be strong enough to run with main circuit characteristic that produced by the weaker one, the opposite Directed field to destroy and in addition, the engine the desired To give series connection characteristics.

Um durch die sich entgegenwirkenden Reihenschlußwicklungen nicht zuviel Raum auf den Polen zu verlieren, kann die Wirkung der schwächeren Reihenschlußwicklung durch geeignete Führung der Verbindungsleitungen der Wendepole an den Hauptpolen vorbei oder um diese herum hervorgebracht werden. Beispiele dafür sind in den Abb. 2 und q. dargestellt, während in den Abb. r und 3 die normalen Verbindungen dargestellt sind, für den Fall, daß Wende- und Hauptpole polweise hintereinandergeschaltet werden.So as not to do too much through the opposing series windings Losing space on the poles can have the effect of the weaker series winding by suitably routing the connecting lines of the reversing poles to the main poles be brought about by or around them. Examples of this are shown in Fig. 2 and q. shown, while in Figs. r and 3 the normal connections are shown are, in the event that reversing and main poles are connected one behind the other pole-wise.

Abb. r und 2 stellen den Fall dar, daß die Wendepole eine volle Anzahl von Windungen haben und jeder Hauptpol eine volle Reihenschlußwindung. Abb. 3 und ¢ stellen den Fall dar, daß die Wendepole eine volle und eine halbe Windung aufweisen und nur jeder zweite Hauptpol eine Reihenschlußwicklung besitzt.Fig. R and 2 show the case that the Reversing pole have a full number of turns and each main pole a full series turn. Fig. 3 and ¢ represent the case that the reversing poles a full and a half turn have and only every second main pole has a series winding.
