Abstract

Die Erfindung bezieht sich auf einen doppeltwirkenden elektromagnetischen Aktor (1), insbesondere für Hydraulik- und Pneumatikanwendungen, mit einer Spule (71), einem in der Spule angeordneten Anker (2) mit mindestens zwei in axialer Richtung magnetisierten Permanentmagneten (22,25) und einer Zentralscheibe (23) zwischen den Permanentmagneten, wobei zwischen Anker und Spule in axialer Richtung stärker beziehungsweise leicht magnetisierbare Bereiche (7) und zwischen diesen ein schwach- beziehungsweise nichtmagnetisierbarer Bereich (8) ausgebildet ist. Die Erfindung zeichnet sich dadurch aus, daß der Anker in einem Polrohr (10) angeordnet, insbesondere gelagert ist, das in der Spule vorgesehen ist.
