Abstract

Es wird ein elektromagnetischer Linearaktor beschrieben. Gemäß einem Beispiel der Erfindung umfasst der Linearaktor einen Rahmen (Stator), der zumindest teilweise aus weichmagnetischem Material besteht; einen Anker, der zumindest teilweise aus weichmagnetischem Material besteht und der an dem Rahmen derart gelagert ist, dass der Anker entlang einer Längsachse relativ zum Rahmen bewegbar ist. Anker und Rahmen sind derart ausgebildet, dass entlang der Längsachse in einer offenen Position ein Spalt zwischen Anker und Rahmen vorliegt und in einer geschlossenen Position Anker und Rahmen aneinander anliegen, sodass der Spalt geschlossen ist. Eine erste Ankerspule ist mit dem Anker derart verbunden, dass eine auf die erste Ankerspule wirkende Kraft auf den Anker übertragbar ist. Der Linearaktor umfasst des Weiteren Mittel zum Erzeugen eines Erreger-Magnetfeldes, das zumindest teilweise durch Rahmen und Anker geführt und derart gerichtet ist, dass auf die erste Ankerspule, wenn sie bestromt ist, eine Kraft wirkt, die auf den Anker übertragen wird, um den Spalt zu schließen. Rahmen, Anker und Erreger-Magnetfeld sind dabei derart ausgebildet, dass bei geschlossenem Spalt zwischen Rahmen und Anker eine Haltekraft wirkt.
