Description
Einrichtung zur Erzielung einer bestimmten Abhängigkeit des Drehmomentes von der Drehzahl beim Antrieb von Aufwickelvorrichtungen mittels eines Ferrarismotors Handelt es sich darum, beim Aufwickeln von band-oder fadenförmigen Körpern, z. B. Bild- und/oder Tonträgern oder Garnen, den Bandzug konstant zu. halten, so muß bei sich vergrößerndem Wickeldurch. messer das Drehmoment steigen. Da mit Vergrößerung des Wickeldurchmessers bei konstanter Bandgeschwindigkeit die Drehzahl der Aufwickelvorrichtung fallen muß, besteht die Forderung, zum Antrieb der Aufwickelvorrichtung Motore zu verwenden, bei denen die. Abhängigkeit des Drehmomentes von der Drehzahl der in dem in Frage kommenden Bereich gleichmäßig fallend und möglichst linear ist. Es ist bekannt, daß sich zum Antrieb von Aufwickelvorrichtungen Ferrarismotore gut eignen. Ihr Drehmoment fällt gleichmäßig im ganzen Drehzahlbereich von Null ah aufwärts, im Gegensatz beispielsweise zu Drehfeld-Asynchronmotoren mit hewickeltem Eisenanker, deren Drehmoment hei Drehzahlen von Null an aufwärts erst bis zu einem Maximalwert (Kippmoment) steigt und erst dann abfällt. Mitunter kann auch der Wunsch bestehen, die der Spulenachse ferneren Lagen mit kleinerem Zug aufzuwickeln als die Lagen mit kleinem Durchmesser. Beim Aufwickeln beispielsweise fadenr förmiger Körper (Garne) könnte man damit die Ten denz, daß sich die oberen Lagen in Zwischenräume der unteren Lagen eindrücken. - was beim Abwickeln zu Störungen führen könnte -, bekämpfen. In solchem Falle miißte die Funktion, nach welcher das Drehmoment des Antriebmotors der Drehzahl folgt, konkav in bezug auf die Abszisse sein. Mitunter besteht noch zusätzlich der Wunsch, beim Wechsel der Art des aufznwickelnden Gutes durch einfache Schaltmittel die Abhängigkeit des Drehmomentes von der Drehzahl den neuen Verhältnissen anpassen zu können. Device to achieve a certain dependency of the torque on the speed when driving winders by means of a Ferrari motor Is it a matter of winding up tape-shaped or thread-shaped bodies, e.g. B. Image and / or sound carriers or yarns, the tape tension to constant. hold, so must increasing wrap. the torque increases. As with enlargement the winding diameter at constant belt speed the speed of the winding device must fall, there is a requirement to drive the winder to motors use where the. Dependence of the torque on the speed of the in the area in question falls evenly and is as linear as possible. It it is known that Ferrari motors are good for driving winders suitable. Your torque falls evenly over the entire speed range from zero ah upwards, in contrast, for example, to rotary field asynchronous motors with a wound iron armature, their torque at speeds from zero upwards only up to a maximum value (Overturning moment) increases and only then decreases. Sometimes there may also be a desire wind the layers further from the coil axis with less tension than the layers with a small diameter. When winding, for example, threadlike bodies (yarns) One could thus use the tendency for the upper layers to be in the spaces between the lower ones Press in layers. - which could lead to disturbances when unwinding - fight. In such a case the function would have to be, according to which the torque of the drive motor the speed follows, be concave with respect to the abscissa. Sometimes still exists in addition, the desire to change the type of goods to be wound by simple Switching means the dependence of the torque on the speed of the new conditions to be able to customize.
Gemäß der Erfindung werden diese Aufgaben durch hesondere Schaltmittel außerhalb des Ferrarismotors gelöst. Versuche haben die Erkenntnis. gebracht, daß durch Veränderung von Erregungsstrom, Steuerstrom und relativer Phasenlage dieser beiden Ströme mit an sich bekannten Mitteln wie Spannungsteilern. und Kondensatoren, die in die Zuleitungen der Haupt- und Hilfsphase des Ferrarismotors eingeschaltet sind, eine Beeinflussung der Abhängigkeit des Drehmomentes von der Drehzahl in einem praktisch zur Lösung der obengenannten Aufgabe hinreichendem Maß möglich ist. According to the invention, these objects are achieved by special switching means solved outside the Ferrari engine. Experiments have the knowledge. brought that by changing the excitation current, control current and relative phase position of these two currents with known means such as voltage dividers. and capacitors, which are switched into the leads of the main and auxiliary phases of the Ferrari engine are influencing the dependence of the torque on the speed in one is practically possible to solve the above problem to a sufficient extent.
