Description

Es sind sogenannte Tauchmagnete bekannt, bestehend aus einer in einzelne Spulen unterteilten Erregerspule und einem darin längs beweglichen Anker. Derartige Magnete werden als Hub- oder Lüftmagnete zur Betätigung von Bremsen bei Kranen od. dgl. angewendet.So-called diving magnets are known, consisting of one in individual Coils subdivided excitation coil and an armature which can be moved longitudinally therein. Such Magnets are used as lifting or lifting magnets for the actuation of brakes on cranes or. Like. Applied.

Tauchmagnete werden nun auf den verschiedensten Gebieten gern verwendet. Die Bewegung des Ankers ist nämlich sehr elastisch, da er nicht wie bei Magneten mit einem festen Eisenkern und an diesen anschlagendem Anker in seiner Endstellung starr festgehalten wird; vielmehr gibt er, gewissermaßen wie an Gummifäden aufgehängt, Stößen, die von außen her kommen, pendelnd nach. Ein Mangel dieser Tauchmagnete besteht nun darin, daß sie einen verhältnismäßig geringen Ankerhub haben und daß bei einer bestimmten Länge der Erregerspule die Hubhöhe kaum nennenswert geändert werden kann.Solenoid magnets are now popularly used in a wide variety of fields. The movement of the armature is very elastic because it is not like magnets with a fixed iron core and an anchor that strikes it in its end position is held rigidly; rather, it gives, as if suspended from elastic threads, Bumps that come from the outside, pendulously afterwards. A lack of these solenoids is now that they have a relatively low armature stroke and that with a certain length of the excitation coil, the lifting height hardly changed significantly can be.

Die Erfindung schlägt nun vor, daß der Anker ebenfalls fortlaufend einschaltbare Stromspulen trägt. Es können damit sowohl die Spulen der Erregung als auch die Ankerspulen einzeln oder in Gruppen nacheinander eingeschaltet werden, so daß der Anker diesem Fortgang der Schaltung bis zur letzten Spule folgt. Der Anker kann auch bis zu einer gewissen Tauchtiefe eingezogen werden, indem man nur einen Teil der Spulen erregt. Ein Magnet nach der Erfindung ist in der Abbildung schematisch dargestellt. I ist die Erregerspule, 2 ist der Tauchanker. Die Erregerspule I ist aus mehreren Einzelspulen 3 zusammengesetzt. In dem dargestellten Ausführungsbeispiel ist auch der Anker 2, der an sich einfach als Weicheisenkern ausgebildet sein kann, mit Spulen 4 besetzt, die, wie in der Abbildung dargestellt, in anderer Weise als die Erregerspulen unterteilt sein können.The invention now proposes that the anchor also be continuous carries switchable current coils. It can use both the coils of excitation as well as the armature coils are switched on individually or in groups one after the other, so that the armature follows this progression of the circuit up to the last coil. Of the Anchor can also be retracted to a certain depth by only energized part of the coils. A magnet according to the invention is in the picture shown schematically. I is the excitation coil, 2 is the plunger. The excitation coil I is composed of several individual coils 3. In the illustrated embodiment is also the armature 2, which can simply be designed as a soft iron core, occupied by coils 4, which, as shown in the figure, in a different way than the excitation coils can be divided.

Die Schaltung der Spulen kann von Hand oder automatisch in bekannter Weise vorgenommen werden, wobei die Schaltung sowohl der Erregerspule als auch der Ankerspulen beliebig erfolgen kann, wodurch die Zugkraft des Tauchmagneten den Erfordernissen angepaßt werden kann.The switching of the coils can be done manually or automatically in a known manner Way can be made, the circuit of both the excitation coil and the Armature coils can be made arbitrarily, whereby the tensile force of the solenoid meets the requirements can be customized.
