Abstract
Description
Die Erfindung betrifft ein Verfahren beim Einsatz von mehreren Synchronmotoren zum Antrieb eines gemeinsamen Arbeitsorganes, wobei für die Speisung der Synchronmotoren nur ein gemeinsamer Frequenzumrichter vorgesehen ist, der durch einen Drehwinkelgeber am Läufer nur eines der Synchronmotoren gesteuert wird.The The invention relates to a method when using multiple synchronous motors for driving a common working organ, wherein for the power supply the synchronous motors provided only a common frequency converter is, by a rotary encoder on the rotor only one of the synchronous motors is controlled.
Wenn mehrerer Synchronmotoren über die von ihnen angetriebenen Arbeitsorgane bspw. an Spinnereimaschinen über einen gemeinsamen Tangentialriemen oder eine Streckwalze an mehreren Stellen entlang ihrer Länge mechanisch in Verbindung stehen, muss sichergestellt werden, dass alle Synchronmotoren an dem von ihnen gemeinsam angetriebenen Arbeitsorgan von einer übereinstimmenden Ausgangs-Winkellage ausgehen, damit sie durch die Speisefrequenz des gemeinsamen FU phasengleich bestromt werden können.If several synchronous motors via the driven by them working organs, for example, on spinning machines on a common Tangentialriemen or a draw roller in several places along its length be mechanically connected, it must be ensured that all synchronous motors on the jointly driven by them working organ from a matching one Starting angular position go out, so they through the feed frequency the common FU can be energized in phase.
Der Erfindung war daher die Aufgabe gestellt, die übereinstimmende Ausgangs-Winkellage aller nur ein gemeinsames Arbeitsorgan antreibender Synchronmotoren zu gewährleisten. Sie löst diese Aufgabe dadurch, dass zwischen den Synchronmotoren und ihren Übertragungsorganen auf das Arbeitsorgan eine lösbare Kupplung insbesondere in Form einer Spannbüchse angeordnet ist. Nach Ausrichten des Arbeitsorgans werden die Synchronmotoren bei gelöster Kupplung durch Gleichstrom oder auf Stillstand eingestelltem Drehstrom beaufschlagt und dadurch in die angestrebte Ausgangs-Winkellage gebracht. In dieser werden dann die Spannbüchsen angezogen und die Ausgangs-Winkellage fixiert.Of the Invention was therefore the task of the matching output angular position of all only a common working organ driving synchronous motors too guarantee. She dissolves this task in that between the synchronous motors and their transmission organs on the working organ a detachable Coupling is arranged in particular in the form of a clamping bush. After aligning of the working organ are the synchronous motors when the clutch is released acted upon by direct current or at standstill set three-phase current and thereby brought into the desired output angular position. In this then the clamping sleeves tightened and fixed the initial angular position.
Die Erfindung wird im Folgenden am Beispiel eines Axialfeldmotors dargestellt und beschrieben. Die Erfindung ist jedoch nicht auf derartige Motoren beschränkt, vielmehr kann sie an allen Bauarten von Synchronmotoren verwirklicht werden.The Invention is shown below using the example of a Axialfeldmotors and described. However, the invention is not limited to such engines, but rather It can be realized on all types of synchronous motors.
Unter einem Axialfeldmotor wird im Folgenden ein Motor verstanden, der im Ständer mehrere auf einem Paket von Jochblechen angeordnete, axial ausgerichtete Erregerwicklung und auf dem mindestens einen scheibenförmigen Läufer mit mehreren, der Erregerwicklung gegenüber stehende Permanentmagnete aufweist.Under an axial field motor is understood below an engine that in the stand a plurality of axially aligned on a package of yoke plates arranged Excitation winding and on the at least one disc-shaped rotor with several, the exciter winding opposed permanent magnets having.
Dadurch, dass im Läufer kein Magnetfeld induziert werden muss, da seine Magnetisierung durch die Permanentmagnete gegeben ist, hat der Motor gegenüber einem Asynchronmotor einen besseren Wirkungsgrad. Da die Permanentmagnete dem umlaufenden Erregerfeld schlupffrei folgen, läuft der Motor synchron mit dem umlaufenden Statorfeld. Derartige Axialfeldmotoren weisen einen einfachen Aufbau auf, der wenig Materialeinsatz erfordert und daher kostengünstig zu fertigen ist. Er weist daher auch gegenüber einem Synchronmotor geläufiger Bauart elektrisch Vorteile auf, so dass sein Antriebsumrichter „kleiner" ausgeführt werden kann.Thereby, that in the runner no magnetic field needs to be induced, since its magnetization through the Given permanent magnets, the engine has opposite Asynchronous motor better efficiency. Because the permanent magnets Follow the circulating exciter field slip - free, runs the Motor synchronous with the rotating stator field. Such axial field motors have a simple structure that requires little use of material and therefore inexpensive to be finished. He therefore has also compared to a synchronous motor of common design electrical Advantages, so that its drive converter can be made "smaller".
Die Erfindung wird im Folgenden beim Einsatz derartiger Axialfeldmotoren in einem speziellen Anwendungsfall an Spinnmaschinen dargestellt. Ihre Anwendung ist jedoch nicht auf den Antrieb von Tangentialriemen beschränkt. Vielmehr betrifft sie alle Fälle, in denen von einem gemeinsamen Frequenzgenerator gespeiste Synchronmotoren hinsichtlich ihrer Drehwinkelstellung einerseits durch die Phasenlage ihrer Speisefrequenz elektrisch und andererseits durch das gemeinsam angetriebene Arbeitsorgan mechanisch gekoppelt sind. Sie haben in diesem Falle nicht die Möglichkeit, sich beim Anlauf frei in die Phasenlage zu drehen.The Invention will be described below when using such Axialfeldmotoren represented in a special application to spinning machines. However, their application is not on the drive of tangential belts limited. Rather, it concerns all cases in those powered by a common frequency generator synchronous motors in terms of their angular position on the one hand by the phase position their supply frequency electrically and the other by the common driven working member are mechanically coupled. You have in In this case, it is not possible to to turn freely during startup in the phase position.
Dabei ist vorgesehen, mehrere, bspw. zehn, in annähernd gleichen Abständen entlang eines Tangentialriemens angeordnete Axialfeldmotoren zum Antrieb des gemeinsamen Tangentialriemens einzusetzen. Da alle Axialfeldmotoren synchron laufen, übertragen sie in gleichen Abständen Energie auf den Tangentialriemen und verhindern seine unterschiedliche Dehnung.there is provided, several, for example. Ten, at approximately equal intervals along a Tangentialriemens arranged axial field motors for driving of the common tangential belt. Since all axial field motors run synchronously, transmitted they at equal intervals Energy on the tangential belts and prevent its different Strain.
Ein Auflegen des Tangentialriemens auf seine auf den Wellen der Axialfeldmotoren angeordneten Riemenscheiben erfolgt in aller Regel dadurch, dass mindestens einer der Axialfeldmotoren quer zum Lauf des Tangentialriemens verschoben und der Tangentialriemen dabei gespannt wird. Dabei wird der Riemen unvermeidlich gelängt und verschoben. Dies hätte zur Folge, dass andere Axialfeldmotoren über ihre Riemenscheiben aus der erforderlichen Ausgangslage gedreht würden.One Apply the tangential belt to its on the shafts of the axial field motors arranged pulleys usually takes place in that at least one of the Axialfeldmotoren across the barrel of the tangential moved and the tangential belt is stretched. It is the Belt inevitably lengthened and moved. This would have cause other axial field motors to over their pulleys the required starting position would be rotated.
Um dies zu verhindern, sieht die Erfindung vor, dass alle Axialfeldmotoren im Stillstand durch Bestromung mit Gleichstrom oder auf Drebzahl Null geregeltem Speisestrom in einheitliche Ausgangslage gebracht und bis zum Anziehen der Spannbüchsen in ihr gehalten werden.Around To prevent this, the invention provides that all axial field motors at standstill by current supply with DC or to Drebzahl Zero regulated supply current brought into a uniform starting position and until tightening the clamping sleeves to be held in her.
Der den gemeinsamen FU steuernde Drehfeldgeber bietet die Möglichkeit, auf einen zusätzlichen Drehzahlgeber zu verzichten, der notwendig wäre, um sogenannte Master/Slave-Antriebskonfigurationen zu realisieren.Of the The rotary field transmitter controlling the common FI offers the possibility on an additional To dispense with speed sensor, which would be necessary to so-called master / slave drive configurations to realize.

Diese Vorgehensweise ist bei allen Bauarten von Synchronmotoren sinnvoll und erforderlich, wenn vorgesehen ist, sie durch nur einen gemeinsamen Frequenzumrichter zu speisen. Ein anderer sinnvoller Anwendungsfall wäre der Antrieb einer langen Streckwalze durch mehrere, über ihre Länge verteilte Synchronmotoren. Auch hier wären die Synchronmotoren durch die mechanische Koppelung über die Streckwalze an einem freien Einstellen auf die Phasenlage der Speisefrequenz gehindert.These This approach makes sense in all types of synchronous motors and required if provided by only one common frequency converter to dine. Another useful application would be the drive a long drafting roller by a plurality of synchronous motors distributed over their length. Also here would be the synchronous motors through the mechanical coupling via the draw roll at a free setting on the phase position of the supply frequency prevented.
