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.

Electromagnetic actuator drive

The present invention relates to a high-speed controlling device, suitable for displacing a switching element between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature, with a driven coupling to the switching element, is arranged. According to the invention, said armature contacts the first electromagnet in the first position of the switching element and contacts the other electromagnet in the second position of the switching element. In order to obtain particularly short switching times for the switching element, the armature can be firmly secured to a shaft, which is rotatably mounted about its longitudinal axis and to which said switching element is also fixed in an axially offset manner in relation to the armature.
