Abstract
An adjusting device for precise rotary angle adjustment of final control elements in closed- or open-loop control devices. The adjusting device comprises a rotary magnet apparatus in which parallel air gaps are formed between the poles of the armature and the magnet poles of the armature counterpart. In order to attain constant torques over the angle of rotation of the armature, when the electric current applied to the coil is constant, the end faces of the armature poles are embodied as wedge-shaped.
