Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Einstellung eines Abstandes (20) innerhalb eines magnetischen Kreises, insbesondere des Abstandes (20) zwischen einem Magnetanker (1) und einem Magnetkern (10), wobei der Magnetanker (1) eine Ankerplatte (2) und einen Ankerbolzen (7) aufweist, die in einer Relativlage (21) miteinander gefügt werden, dadurch gekennzeichnet, dass nach der Montage des Magnetankers (1) aus Ankerplatte 2 und Ankerbolzen 7 die Relativlage (21) zwischen der Ankerplatte (2) und dem Ankerbolzen (7) im Rahmen eines Pressvorganges auf ein erstes definiertes Maß (24) oder ein zweites definiertes Maß (27) eingestellt werden.
