ABSTRACT:
A rotational actuator for the interior of an adjustable vehicle suspension damper device comprises a cylindrical permanent magnet stator and a cylindrical armature. The armature includes a shaftless winding on a non-magnetic armature frame, the armature frame extending axially beyond the winding at each end with output engaging means at one end and an opening between that end and the winding projecting radially inward across the axis of the armature. A first shaft coaxial with the armature is anchored in the one axial end of the armature frame and rotatably supported in a first axial support. A second axial support in the stator projects into the opening of the armature frame across the armature axis and supports a second shaft coaxial with the armature and extending across the opening of the second axial end of the armature frame, whereby the armature is supported at each axial end close to the winding and core while the radial size of the actuator is minimized. Rotational limit stops may be formed on the bridge portion of the armature adjacent the radially inwardly projecting opening and on the second support means. An additional intermediate stop may comprise flat surfaces on the armature and a stationary U-shaped spring; or output ratchet apparatus may be provided.
