Abstract

Die Erfindung betrifft einen elektromagnetischen Stellantrieb (1) zum Verstellen eines Stellglieds zwischen wenigstens drei Stellungen, umfassend einen weichmagnetischen Anker (2), der mit dem Stellglied antriebsgekoppelt ist und mehrere Ankerflächen (5, 6) aufweist, mehrere weichmagnetische Polelemente (7), die mehrere Polflächen (8, 9) aufweisen, an denen die Ankerflächen (5, 6) in zwei Endstellungen des Ankers (2) zur Anlage kommen, eine Rückstelleinrichtung (10), die den Anker (2) mittels Federkraft in eine liegende Ausgangsstellung antreibt, und eine Halteeinrichtung (11), mit deren Hilfe der Anker (2) in seinen Endstellungen mittels elektromagnetischer Kräfte festlegbar ist.The invention relates to an electromagnetic actuator (1) for adjusting an actuator between at least three positions, comprising a soft magnetic armature (2) which is drive coupled to the actuator and a plurality of armature surfaces (5, 6), a plurality of soft magnetic pole elements (7) a plurality of pole faces (8, 9) on which the armature surfaces (5, 6) come into abutment in two end positions of the armature (2), a restoring device (10) which drives the armature (2) by means of spring force into a lying starting position, and a holding device (11), by means of which the armature (2) can be fixed in its end positions by means of electromagnetic forces.

Um den Stellantrieb (1) preiswerter zu realisieren, kann eine gerade Anzahl von mindestens vier Polelementen (7) vorgesehen sein, jedem Polelement (7) eine separate elektromagnetische Spule (12) zugeordnet sein und die Halteeinrichtung (11) zum Festlegen des Ankers (2) in dessen Endstellungen die Spulen (12) so bestromen, dass die Polflächen (8, 9) benachbarter Polelemente (7) gegensinnig gepolt sind.

Figure imgaf001
In order to realize the actuator (1) cheaper, an even number of at least four pole elements (7) may be provided, each pole element (7) to be associated with a separate electromagnetic coil (12) and the holding device (11) for securing the armature (2 ) in the end positions of the coils (12) energized so that the pole faces (8, 9) of adjacent pole elements (7) are poled in opposite directions.
