    • A rotary actuator for setting the rotation angle of control elements, especially of a throttle device which determines the flow cross-section in a line through which flow passes, for internal-combustion engines, having an electric actuating motor with a two-pole stator, stator winding and two-pole permanent-magnet rotor. In order to achieve a compact construction and manufacture which is easy in production-engineering terms, the stator poles are constructed as claw poles which are connected on opposite end sides in each case to an annular jacket for the magnetic return path, which jacket surrounds the claw poles with a radial gap. The stator winding is located as an annular coil in the annular space between the annular jacket and the claw poles. In order to produce latching of the permanent-magnet rotor outside the claw pole gaps when no current is flowing in the stator winding, the claw poles are designed asymmetrically in such a manner that, on the one hand, the radial air gap width in the central claw pole region is greater than in the two claw pole edge regions and the radial widths of the claw pole edge regions are a different size.

    • A known servo-drive including a stator which is formed with two-component design or the exciter winding has to be attached directly to the stator, which is associated with a costly production method. The new servo-drive is to permit easy and cost-effective manufacture with favorable actuation properties. The stator of the servo-drive includes in the region of the poles, weak points which are formed either by recesses or by gaps. An induction core includes a winding which is inserted into a yoke constructed on the stator by which a magnetic field can be induced in the stator. The alternating combination of sheet-metal laminas having gaps and recesses permits the torque/rotary angle characteristic of the servo-drive to be optimized with favorable production properties. The servo-drive for rotary angle adjustment of an actuator is used for example to control the opening cross-section of a medium-conducting flow line in internal combustion engines for the purpose of controlling idling speed.
