A bistable electromagnetic actuator device, a permanent magnet means (), as well as an armature unit () with an elongate plunger unit () extending along a moving direction, wherein said armature unit can be moved into at least one of two end and/or stop positions that are stable in the deenergized state by means of stationary electromagnetic driving means (), wherein stationary magnetic field detector means () are assigned to a housing (), which at least sectionally encloses the armature unit, for the contactless interaction with the permanent magnet means in at least one of the end or stop positions provided for the armature position detection, wherein the plunger unit features a terminal contact and/or engagement section () for interacting with an actuating partner in a contacting and non-positive fashion such that a non-positive contact and/or actuation by the actuating partner causes a motion of the armature unit into one of the end or stop positions, in which the armature unit remains in a stable fashion in the deenergized state, when the electromagnetic driving means are deactivated, and wherein the magnetic field detector means are arranged and wired for generating and outputting a detector signal corresponding to this end or stop position.

Bistable electromagnetic actuator device

An electromagnetic actuator device has a coil unit () enclosing a first yoke section () of a stationary yoke unit (), an armature unit () movably guided relative to the yoke unit (), by energization to interact with a positioning partner on the output side of the armature unit () and permanent magnetic agents () coupled into a magnetic flux circuit of the yoke unit () wherein de-energization of the coil unit () a permanent magnetic flux circuit through the yoke unit () and a section of the armature unit () that is free of permanent magnetic flux and energization displaces the permanent magnetic flux, out of the section, wherein the armature unit (), by spring force is pre-loaded in a direction opposed to permanent magnetic retaining force of the armature unit () and the positioning partner is a combustion engine unit.

Electromagnetic actuator device

An electromagnetic actuating device, in particular camshaft adjustment device, having an armature unit () which can be driven in the axial direction or parallel thereto in reaction to energization of a stationary, axially oriented coil unit () and is designed to interact with a slide and/or plunger unit () which extends in the axial direction, in particular a plunger unit which brings about camshaft adjustment of an internal combustion engine, wherein permanent magnet means are provided on and/or in the armature unit and/or the slide or plunger unit, and the coil unit and armature unit are accommodated at least partially in a housing unit or carrier unit.
