Abstract

The object of employing permanent magnet i.e. material in conjunction with a solenoid etc., is to eliminate the need for mechanical springs for resetting the armature into its quiescent position. Permanent magnet inserts can be used for solenoids with either direct or alternating current excitation. In an example of an ac solenoid the plunger n2) can be held in a raised position by permanent magnet insert (3) at the end of the coil case. The armature may be either suspended from the magnet, or in contact with it, when at rest. Permanent magnet insert may also be used for damping the motion of the armature. A ring of permanent magnet i.e. material coaxial with the armature, and placed near one end of its travel, will provide a damping force.

Description

Elektro.agnet (Kurzhubiagnete) mit permanentmegnetischer Rückholung Electro magnet (short stroke coil) with permanent magnet return

und Ddmpfung des Ankers Um die Magnetkombination nicht durch eine Federcharakteristik zu beeinträchtigen wird als Neuerung vorgeschlagen, einen Wechselstrom- oder Gleichstrommagneten die Ankerrückholung mittels einem Permanentmagneten zu bewerkstelligen. and damping of the armature To impair the spring characteristic is proposed as a novelty, an alternating current or DC magnets, the armature retraction by means of a permanent magnet accomplish.

Abbildung 1 zeigt beispielsweise einen Wechselstrommagneten, dessen svnker in der Ausgangslage von einen Permanentmagneten beispielsweise schwebend festgehalten wird.For example, Figure 1 shows an AC magnet whose svnker floating in the starting position of a permanent magnet, for example is being held.

Abbildung 2 zeigt beispielsweise einen Gleichstrommagneten, dessen Anker von einem Permanentiogneten direkt gehalten wird.For example, Figure 2 shows a DC magnet whose Anchor is held directly by a Permanentiogneten.
