Abstract

Ein Elektromagnet ist mit einem zylinderförmigen Magnetanker, der in einer Hülse beweglich geführt ist, mit einem dem Magnetanker stirnseitig gegenüberliegend angeordneten Polkern, und mit einer Antiklebscheibe aus einem nicht magnetischen Material, die zwischen dem Magnetanker und dem Polkern angeordnet ist, ausgestattet. Am Polkern ist eine ringartige Erhebung gebildet, die eine dem Magnetanker zugewandte Fläche überragt. In der ringartigen Erhebung ist radial innenseitig eine Nut gebildet. Die Antiklebscheibe ist durch Eingriff in die Nut formschlüssig am Polkern befestigt.
