An electromagnetic actuator device, comprising a coil unit, which surrounds a first yoke section of a stationary yoke unit and is activated by energizing the coil unit, and armature elements, which are guided so as to be movable relative to the yoke unit and which interact with an output-side actuating partner and are driven in order to perform an actuating movement, the armature elements interact with at least one second yoke section of the yoke unit to form an air gap lying outside of the first yoke section for a magnetic flux produced by the activated coil unit. Permanent magnet elements are connected magnetically parallel to the coil unit in such a way that a permanent-magnet magnetic flux of the permanent magnet elements through the first yoke section can occur, a coil magnetic flux of the coil unit flowing across the air gap is overlaid in a magnetically parallel and/or equally directed manner with a permanent-magnet magnetic flux of the permanent magnet elements flowing across the air gap, and activation of the coil unit by means of energizing causes an at least partial magnetic flux shift, in particular magnetic flux displacement, of the permanent-magnet magnetic flux of the permanent magnet elements from the first yoke section to the second yoke section.

Electromagnetic actuator device

An electromagnetic actuator device, comprising a coil unit (), which surrounds a first yoke section () of a stationary yoke unit and can be activated by energizing the coil unit; and armature elements (), which are guided so as to be movable relative to the yoke unit and which interact with an output-side actuating partner and which can be driven in order to perform an actuating movement. The armature elements interact with at least one second yoke section () of the yoke unit to form an air gap () for a magnetic flux produced by the activated coil unit.
