ABSTRACT:
The direct drive for a throttle valve shaft in a throttle valve manifold comprises a coil and a rotor arranged directly adjacent to the coil. The rotor is made from a steel ring inside which a first inner magnetic shell and a second inner magnetic shell lie opposite each other. The steel ring has a first outer magnetic shell and a second outer magnetic shell lying opposite each other on the outside thereof. The steel ring is connected to the throttle valve shaft on the end thereof facing the throttle valve. A sensor for position recognition of the throttle valve is arranged in the middle of that region of the end of the steel ring facing away from the throttle valve.
