Electromagnetic drive mechanism

摘要

The drive includes two electromagnets, whose pole surface areas face each other at least partially, and a movable armature arranged reciprocating between these pole surface areas. The armature is held in an intermediate position through spring forces while the magnets are switched off. The armature is brought at switching on of one of the magnets into one of two end positions, at least nearby the pole surface areas of the corresponding electro-magnet. The armature is connected with the part to be driven, and held in a spring bearing, preferably formed by plate-springs (8,9).
