Abstract
The present invention relates to an electromagnetic actuator drive () for adjusting an actuator drive among at least three positions, comprising a soft magnetic armature () which is drive-coupled to the final controlling element and has a plurality of armature faces (), a plurality of soft magnetic pole elements () having a plurality of pole faces () on which the armature faces () come to rest in two end positions of the armature () a restore position () which drives the armature () by spring force into a horizontal starting position, and a holding device () with the help of which the armature () can be secured in its end positions by electromagnetic forces. To implement the actuator drive () less expensively, an even number of at least four pole elements () may be provided, a separate electromagnetic coil () being assigned to each pole element () and electric power being applied to the holding device () for securing the armature () in its end positions, the holding device applying electric current to the coils () so that the pole faces () of adjacent pole elements () are oppositely polarized.
