Description

Verfahren zur Erzielung einer hin und her gehenden Bewegung mittels eines in einer Spule beweglich angeordneten Magnetkerns Zur Erzielung einer hin und her gehenden Bewegung sind Einrichtungen bekannt, die aus Spulen mit Magnetkernen bestehen, von denen ein Teil beweglich ist. Zum Zwecke der Bewegung in einer Richtung muß hierbei die Spule eine gewisse Zeit vom Strom durchflossen werden, worauf eine Feder oder eine in der Gegenrichtung wirkende Spule die Rückbewegung veranlaßt. Hierbei waren bisher Umschaltvorrichtungen erforderlich, die durch die vorliegende Erfindung vermieden werden.Method for achieving a reciprocating movement by means of a magnetic core movably arranged in a coil to achieve a and moving motion devices are known that consist of coils with magnetic cores exist, part of which is movable. For the purpose of moving in one direction the coil must be traversed by the current for a certain time, whereupon a Spring or a coil acting in the opposite direction causes the return movement. Here switching devices were previously required by the present Invention to be avoided.

Erfindungsgemäß wird die Spule mit Wechselstrom über einen Transformator gespeist, der in an sich bekannter Weise mit Gleichstrom annähernd bis zur Sättigung vormagnetisiert ist. Die Rückbewegung des Kernes kann auch hier durch eine Feder erfolgen. Die Wirkungsweise einer solchen Einrichtung ist leicht aus den Abb. I und 2 zu erkennen. In Abb. I ist die Induktion B eines Transformators in Abhängigkeit von den Amperewindungen aufgetragen. Der die Spule speisende Transformator ist bereits mit Gleichstrom bis zum Punkt I der Magnetisierungskurve vorgesättigt. Die beiden Halbperioden des den Transformator außerdem speisenden Wechselstromes rufen MMKe in den Richtungen 2 bzw. 3 hervor. Die Verstärkung der Amperewindungen in Richtung 2 wird infolge der bereits vorhandenen Sättigung eine nennenswerte Steigerung des Flusses nicht hervorrufen; anders die andere Halbperiode des Wechselstromes, die in Richtung 3 und damit der Gleichstrommagnetisierung entgegenwirkt. Die sich hieraus ergebende Charakteristik wird in Abb.2 dargestellt, in der die Spannung in Abhängigkeit von der Zeit aufgetragen ist. Man erkennt, daß nur eine Halbperiode des Wechselstromes den Kern beeinflußt, während die zweite für die Bewegung praktisch unwirksam ist.According to the invention, the coil is supplied with alternating current via a transformer fed, which in a known manner with direct current almost to saturation is premagnetized. The return movement of the core can also be done here by a spring take place. The mode of operation of such a device can easily be seen in Fig. I. and 2 to be recognized. In Fig. I the induction B of a transformer is dependent plotted from the ampere turns. The transformer feeding the coil is already on Presaturated with direct current up to point I of the magnetization curve. The two Half-periods of the alternating current also feeding the transformer call MMKe in directions 2 and 3 respectively. The amplification of the ampere turns towards 2, due to the already existing saturation, there will be a noticeable increase in the Do not evoke flow; otherwise the other half cycle of the alternating current that in direction 3 and thus counteracts the direct current magnetization. The result of this The resulting characteristic is shown in Fig. 2, in which the voltage as a function of is plotted from the time. It can be seen that only a half cycle of the alternating current affects the core, while the second is practically ineffective for movement.

Wird zum Zweck der Rückbewegung eine zweite Spule mit einem zweiten Transformator verwendet, so muß dessen Gleichstrommagnetisierung derartig erfolgen, daß Gleich- und Wechselstrom-Ampere-Windungen in entgegengesetztem Sinne wie beim Transformator für die erste Spule aufeinander wirken.For the purpose of the return movement, a second coil with a second Transformer is used, its DC magnetization must be done in such a way that that direct and alternating current ampere-turns in the opposite sense as with Transformer for the first coil interact.

Eine Ausführungsform der Erfindung zeigt die Abb. 3. Hier wird .die Einrichtung zur Erzielung der hin und her gehenden Bewegung durch die beiden Spulen .4 und 5 gebildet, die einen Magnetkern 6 abwechselnd in der einen oder anderen Richtung bewegen. Die Spulen 4 und 5 werden von zwei Transformatoren 7 bzw. 8 gespeist, die primär von einem Wechselstromnetz 9 erregt werden. Beide Transformatoren erhalten aus einem Gleichstromnetz Io eine Vormagnetisierung derart, daß die Gleichstrom-Ampere-Windungen gegenüber den Wechselstrom-Ampere-Windungen im Transformator 7 entgegengesetzt wirken wie im Transformator 8. Hierdurch erreicht man, daß die beiden Spulen abwechselnd magnetisiert werden und im Takte der Halbperioden den Anker hin und her bewegen.An embodiment of the invention is shown in Fig. 3. Here .die Device for achieving the reciprocating movement through the two coils .4 and 5 formed, which alternate a magnetic core 6 in one or the other Move direction. The coils 4 and 5 are made of two transformers 7th or 8, which are primarily excited by an alternating current network 9. Both transformers receive a bias from a direct current network Io such that the direct current ampere-turns act opposite to the alternating current ampere turns in the transformer 7 as in transformer 8. This means that the two coils alternate are magnetized and move the armature back and forth in the cycle of the half-periods.

Es ist ohne weiteres möglich, mehrere Einrichtungen mit einem oder zwei Transformatoren zu speisen. Der zur Speisung der Transformatoren notwendige Gleichstrom kann praktisch ebenfalls dem Wechselstromnetz entnommen werden. Hierbei können alle bekannten Gleichrichteranordnungen, wie Vakuumröhren, Einankerumformer usw., benutzt werden. Durch Beeinflussung der Periodenzahl des primären Wechselstromes kann die Taktzahl der Arbeitsmaschinen geändert werden.It is easily possible to have multiple facilities with one or to feed two transformers. The one necessary to feed the transformers Direct current can practically also be taken from the alternating current network. Here can use all known rectifier arrangements, such as vacuum tubes, single armature converters etc., can be used. By influencing the number of periods of the primary alternating current the cycle rate of the working machines can be changed.
