ABSTRACT:
An actuator (1) has two parts in the iron circuit and has a simple construction. A short-circuit element (3) has an offset (90), which depending on the position of an armature (9) varies the course (60) of magnetic flux in such a way that over the entire stroke, a constant, high magnetic force is achieved, and thus a shallow course of magnetic force in stroke is attained.
