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.

The invention relates to a double-acting electromagnetic actuator (1), in particular for hydraulic and pneumatic applications, comprising a coil (71), an armature (2) arranged in the coil with at least two permanent magnets (22, 25) magnetized in the axial direction and a central disk (23) between the permanent magnets, wherein between armature and coil in the axial direction stronger or slightly magnetizable areas (7) and between these a weakly or nichtmagnetisierbarer area (8) is formed. The invention is characterized in that the armature in a pole tube (10) arranged, in particular is mounted, which is provided in the coil.
