Beschreibung
Zusammenfassung:	An electromechanical linear actuator includes a threaded drive which has a threaded spindle and a threaded nut. The threaded spindle is coupled to a hollow shaft of an electric motor via a rotationally fixed connection. The threaded nut is fastened to a linearly movable extension tube. In a maximally retracted state of the extension tube, the threaded nut is retracted at least in portions, preferably completely, into the interior of the hollow shaft. During operation of the linear actuator, the threaded spindle rotates and is not moved linearly. The threaded nut does not rotate and is moved linearly.
