Apparatus for controlling armature movements in an electromagnetic circuit

摘要

An electromagnetic circuit for controlling armature movement includes a holding magnet having a magnet yoke provided with a pole face; a solenoid connected to the magnet yoke; a movably supported armature arranged for reciprocating motion toward and away from the pole face along a motion path; an energizing arrangement for passing a current through the solenoid; a measuring pole leg attached to the magnet yoke; and a measuring pole carried by the measuring pole leg. The measuring pole is situated along the motion path of the armature and generates a signal upon passage of the armature by the measuring pole.
