Abstract
An actuator () has two parts in the iron circuit and has a simple construction. A short-circuit element () has an offset (), which depending on the position of an armature () varies the course () 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.
