Abstract

Bekannte elektromagnetische Aktuatoren mit Permanentmagneten weisen zumeist nur in einer Endstellung eine Haltekraft durch den Permanentmagneten auf. Erfindungsgemäß wird nun ein Aktuator Vorgeschlagen, bei dem der Permanentmagnet (6) ortsfest innerhalb des Elektromagneten (2) angeordnet ist und das Rückschlussblech (22) beabstandet vom Permanentmagneten (6) ortsfest angeordnet ist, so dass in einer ersten Endstellung des Ankers (12) ein erster permanentmagnetischer Kreis über den Permanentmagneten (6), das Joch (10), das Rückschlussblech (22) und den Anker (12) geschlossen ist und in einer zweiten Endstellung ein zweiter permanentmagrietischer Kreis über den Permanentmagneten (6), das Joch (10), den Kern (16) und den Anker (12) geschlossen ist.Known electromagnetic actuators with permanent magnets usually have a holding force through the permanent magnet only in one end position. According to the invention, an actuator is proposed, in which the permanent magnet (6) is arranged stationary within the electromagnet (2) and the return plate (22) is arranged at a fixed location at a distance from the permanent magnet (6), so that in a first end position of the armature (12). a first permanent magnetic circuit over the permanent magnet (6), the yoke (10), the return plate (22) and the armature (12) is closed and in a second end position a second permanent magnetic circuit over the permanent magnet (6), the yoke (10 ), the core (16) and the armature (12) is closed.

Ein derartiger Aktuator weist geringe mechanische Belastungen und somit eine hohe Lebensdauer auf, wobei dessen Stellelement in beiden Endpositionen ohne Stromverbrauch gehalten wird.

Figure imgaf001
Such an actuator has low mechanical loads and thus a long service life, wherein the actuator is held in both end positions without power consumption.
