Abstract
The actuator comprises a movable armature swivelling with respect to a stator provided with flanges on which magnets are fitted and a coil fitted around one of the flanges. The magnets have an axial magnetisation in a z axis and are aligned in an x axis. The movable armature is arranged between the magnets in the x axis. The movable armature is mounted on a guide imposing swivelling around a y axis perpendicular to the x and z axes. The movable armature is separated from the magnets by air-gaps. Each magnet forms a static magnetic circuit with one end of the movable armature and one of the flanges. The coil forms a dynamic magnetic circuit with the ends of the movable armature and the flanges.
