Abstract

An electromagnetic final control element is proposed which serves to generate a repeatable rotary motion throughout a limited rotary angle. The electromagnetic final control element includes electrical current supply conductors connected between a plug on the housing and an armature which are formed as elastically deformable conductors secured at one end on an outer roller path body having an outer roller path associated with each current conductor and, on the other end, are secured on an inner roller path body with an inner roller path connected with the armature. Each outer roller path extends eccentrically with respect to the inner roller path whereby the distance between the inner roller path and the outer roller path increases in the roll-off direction of the current conductors from the outer roller path. Thus, it is possible to have an electrical current supply free of retrograde force between the plug and the armature. The ends of the current conductors are eyelet-like and are inserted into corresponding recesses in the inner roller path body and the outer roller path body, respectively. As a result of the contact pins inserted into the eyelet-like ends of the current conduc…
