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.

Figure imgaf001
An electromagnet is equipped with a cylindrical magnet armature which is movably guided in a sleeve, with a pole core arranged opposite the magnet armature, and with an anti-slab of a non-magnetic material which is arranged between the magnet armature and the pole core. At the pole core, a ring-like elevation is formed, which projects beyond a magnet armature facing surface. In the ring-like elevation, a groove is formed radially inwardly. The anti-stick disc is positively secured by engagement in the groove on the pole core.
