Description

Die Erfindung betrifft einen Elektromagneten mit Tauchkern für lange Hübe, welcher insbeson, fiere für die Betätigung von Elektrohämmern, Schützen und Regelklappen verwendet werden kann.The invention relates to an electromagnet with a plunger core for a long time Strokes, in particular, for the operation of electric hammers, shooters and Control dampers can be used.

An sich würde man einen solchen Elektromagneten mit einer dem Hub entsprechenden langen Spule versehen. Um jedoch seine Leistung zu steigern, sind-erfindungsgemäß mehrere geometrisch hintereinander angeordnete Spulen vorgesehen, welche unabhängig voneinander gespeist werden.In itself, such an electromagnet would have a stroke corresponding long coil. However, in order to increase its performance, are-according to the invention several coils arranged geometrically one behind the other are provided which are independent fed from each other.

Nach weiteren Erfindungsgedanken sollen die Magnetspulen einen gemeinsamen äußeren '.Mantel besitzen und ferner durch Eisenscheiben voneinander getrennt sein. Eine besonders zweckmäßige Anwendung des Elektromagneten erfolgt, wenn alle Magnetspulen parallel an die gleiche Spannungsquelle, vorzugsweise an Wechselspannung, angeschlossen sind.According to further inventive ideas, the magnetic coils should have a common outer '.mantel and also be separated from each other by iron disks. A particularly useful application of the electromagnet takes place when all magnet coils connected in parallel to the same voltage source, preferably to AC voltage are.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung. Mit i ist ein gemeinsamer äußerer Mantel für die Magnetspulen 2, 3, 4 bezeichnet. Die Spulen sind durch die Eisenscheiben 5 voneinander getrennt. Der Kern 6 des Elektromagneten wird mit stärkerer Kraft angezogen, als wenn eine einzig-. lange Spule auf ihn wirkte, denn durch die tititerteilung in mehrere Spulen sind die die Anziehungskraft bestimmenden Luftspalte verkürzt worden. Ferner führen die einzelnen Spulen einen stärkeren Strom als eine lange Spule, wenn sie unabhängig voneinander gespeist werden. Sind alle Spulen parallel an die gleiche Wechselspannungsquelle angeschlossen, so führen die Spulen, die der Kern 6 bereits ausfüllt, einen wesentlich schwächeren Strom als die anderen, so daß die Spulen nur während der Einwirkung auf den Kern mit starkem Strom belastet sind. Bei einer einzigen langen Spule hingegen würde der eindringende Kern den Strom drosseln und die Anziehungskraft vermindern.The figure shows an embodiment of the invention. With i is a common outer jacket for the magnet coils 2, 3, 4 is designated. The spools are separated from one another by the iron disks 5. The core 6 of the electromagnet is attracted with stronger force than if a single one. long coil acted on him, because by dividing the titers into several coils, the coils determine the force of attraction Air gaps have been shortened. Furthermore, the individual coils carry a stronger current than a long coil when fed independently. Are all Coils connected in parallel to the same AC voltage source lead to the Coils, which the core 6 already fills, have a much weaker current than the other so that the coils only while acting on the core with strong Electricity are loaded. With a single long coil, however, the penetrating Core to choke the current and reduce the attraction.
