Description
Elektromagnet zum Antriebe von efichrttsehaltwerken mittels zweier Anker Die -Erfindung betrifft solche Elektromagnete, die zwei Anker haben, deren einer träge arbeitet, d. h. verzögert abfällt. Magnete dieser Art dienen dazu, die Schaltarme von Schrittschaltwerken erst geradlinig zu verstellen und dann zu drehen. Einer der Anker; der ohne Verzögerung arbeitet, den Wählstromstößen also folgt, bewegt die Schaltarme, der andere Anker, der erst am Ende der ersten Stromstoßreihe abfällt, bewirkt das Wechseln der Schaltarmbewegung.Electromagnet for drives efichrttsehaltwerken means of two anchor the - invention relates to such electro-magnets, the two armatures, one of which operates slow drops that delayed. Magnets of this type are used to first adjust the switching arms of stepping mechanisms in a straight line and then to turn them. One of the anchors; which works without delay, i.e. follows the selection current surges, moves the switching arms, the other armature, which only drops out at the end of the first series of current pulses, causes the switching arm movement to change.
In der neuen Anordnung steht der Anker, den die Wahlstromstöße steuern, nicht nur unter der Wirkung des Magnetkerns, sondern zugleich unter einer Solenoidwirkung der Wicklung dieses Kerns. Hierdurch wird; wie im folgenden erläutert ist, ein sicheres Arbeiten dieses Ankers erzielt.In the new arrangement, the anchor that controls the elective surges is not only under the action of the magnetic core, but at the same time under a solenoid action the winding of this core. This will; as explained below, a safe one Working this anchor achieved.
Abb. i ist ein perspektivisches Schema eines Beispiels der neuen Anordnung, Abb.2 eine Stirnansicht dazu, gesehen in der Richtung des Pfeiles der Abb. i. Abb. 3 zeigt in einem Grundriß zu Abb.2 einen der Kerne.Fig.i is a perspective diagram of an example of the new arrangement, Fig.2 is a front view of this, seen in the direction of the arrow in Fig. I. Fig. 3 shows one of the cores in a plan of FIG.
Es bezeichnet i die Kerne, 2 die Spulen. Die Spulen sind nur in Abb. z gezeigt, und zwar punktiert angedeutet. Die Kerne i haben je einen Schlitz a und Schenkel b, c, zwischen denen der Schlitz a liegt: Auf den Schenkeln b sitzen Klötze 6 aus Kupfer oder einem anderen, dem Kupfer hier gleichwertigen Metall. Die Kerne sind mittels eines Joches 3, das in Abb. 2 angedeutet ist, aneinander befestigt, z. B. durch Schrauben g, welche in die Klötze 6 eingezogen sind. Der Anker, der sich bei den Klötzen 6 befindet, ist mit 7, seine Schwingungsachse mit 8 bezeichnet. Dieser Anker ist in Abb.2 entfernt gedacht. Der andere Anker ist mit ¢, seine Schwingungsachse mit 5 bezeichnet. Dieser Anker ist U-förmig: Die Spulen 2 ragen dort, - wo der Anker q. sich befindet, über die Kerne i. Der Anker q. reicht mit Seinen Schenkeln in je einender so gebildeten Spulenräume.It denotes i the cores, 2 the coils. The coils are only shown in Fig. z shown, indicated by dotted lines. The cores i each have a slot a and Legs b, c, between which the slot a lies: there are blocks on the legs b 6 made of copper or another metal equivalent to copper here. The cores are attached to one another by means of a yoke 3, which is indicated in Fig. 2, z. B. by screws g, which are drawn into the blocks 6. The anchor that is located at the blocks 6, is designated with 7, its axis of oscillation with 8. This anchor is thought of as removed in Figure 2. The other anchor is with ¢, its axis of oscillation denoted by 5. This armature is U-shaped: the coils 2 protrude there - where the armature q. is located, about the cores i. The anchor q. reaches in with His thighs each one of the coil spaces formed in this way.
Die Spulen 2 wirken dadurch, daß der Anker 4 in sie ragt, als Solenoide auf ihn, so daß der Anker in dem stärksten Teil des magnetischen Feldes liegt und daher schneller angezogen wird, als wenn die Spulen nicht zugleich als Sole-; noide-dienen. Hierbei hilft der Anker 7, nachdem er angezogen ist, dadurch, daß er den magnetischen Stromkreis schließt: Die Abfallzeit des Ankers q. wird dadurch verringert, daß der magnetische Stromkreis nicht nur an einer Stelle, sondern an zwei Stellen d unterbrochen wird. Der Anker 4 folgt also den Stromstößen; die in den Spulen wirksam werden.The coils 2 act as solenoids because the armature 4 protrudes into them on him so that the anchor lies in the strongest part of the magnetic field and is therefore attracted faster than if the coils are not at the same time as brine; noide-serving. This helps the armature 7 after it is attracted by the fact that it has the magnetic Circuit closes: The fall time of the armature q. is reduced by the magnetic circuit interrupted not only in one place but in two places d will. The armature 4 thus follows the current surges; which take effect in the coils.
Beim Unterbrechen des Stromes entstehen in den Klötzen 6 Wirbelströme. Infolgedessen unterliegt in den Kernteilen b das Entstehen und Verschwinden des Magnetismus einer Phasenverschiebung gegenübenden magnetischen Vorgängen in den Kernteilen c, welche bewirkt, daß der Anker 7 verzögert abfällt, d. h. erst dann abfällt, wenn eine Stromstoßreihe beendet ist.When the current is interrupted, 6 eddy currents are generated in the blocks. As a result, in the core parts b, the occurrence and disappearance of the is subject to Magnetism of a phase shift opposing magnetic processes in the Core parts c, which causes the armature 7 to fall off with a delay, d. H. only drops out when a series of impulses is terminated.
Statt der Klötze 6 können Kurzschlußwicklungen angeordnet sein.Instead of the blocks 6, short-circuit windings can be arranged.
