Abstract:
1. A gas flow controlling actuation device comprising: an actuator for shifting an actuation member between a first end position and a second end position; an armature, wherein the armature is mounted in a stator wherein the armature can pivot between the two end positions about a pivot axis, wherein the armature is at least one of connected to the actuation member and is connected in a rotationally fixed manner to the actuation member; at least one electromagnet is arranged wherein the electromagnet is at least one of on the stator and in the stator for generating electromagnetic attractive forces; at least one first stator-side bearing face, wherein an armature first contact face bears against the first stator-side bearing face when the armature is in the first end position; and at least one second stator-side bearing face, wherein an armature second contact face bears against the second stator-side bearing face when the armature is in the second end position, a sensor system, for measuring at least one parameter of a magnetic field produced by the at least one electromagnet during operation of the actuation device, wherein the parameter is dependent on at least on of the armature pivot movement and armature position.
