Abstract

Die Erfindung betrifft eine DC-Elektromagnetanordnung aus geblechten Magnetteilen für den Einsatz in einem elektrischen Schaltgerät, insbesondere in einem Schütz mit einer Antriebsspule, mit einem feststehenden, C-förmigen Magnetjoch 10 mit einem Mittelsteg 12 und zwei Schenkeln 11 und einem bewegbaren, stabförmigen Anker 60, der bei seinem Verschiebungshub durch Führungseinrichtungen 60 geleitet wird, wobei das freie Ende des Ankers 60 auf den Mittelsteg 12 des Magnetjochs 10 gerichtet ist, und zwischen dem freien Ende des Ankers 60 und der Mitte des Mittelstegs senkrecht zur Längsachse des Ankers ein einziger Arbeitsluftspalt 22, ausgebildet ist, und die Schenkelenden 14 nah an den Anker herangeführt sind und nur je einen parasitären Luftspalt bildend vom Anker getrennt sind.
