    摘要: The present invention relates to an actuation device (5) for shifting an actuation member (4) between two end positions, in particular for controlling a gas flow in an internal combustion engine, with an armature (13) which is mounted in a stator (14) such that it can move between two end positions in a pivoting manner about a pivot axis (7) and which is connected or can be connected in a rotationally fixed manner to the actuation member (4), with at least one electromagnet (10), which is arranged on or in the stator (14), for generating electromagnetic attractive forces, with at least one first stator-side bearing face (18), against which a first contact face (20) of the armature (13) bears when the armature (13) is in the first end position, and with at least one second stator-side bearing face (19), against which a second contact face (21) of the armature (13) bears when the armature (13) is in the second end position.Increased reliability can be achieved for the operation of the actuation device (5) by a sensor system (12) for measuring at least one parameter of a magnetic field, which is produced by the at least one electromagnet (10) during operation of the actuation device (5), which parameter is dependent on the armature movement and/or armature position.
