Abstract

Es wird ein Schrauber mit einem Antrieb (12) angegeben, der einen Elektromotor (14) umfasst, der mit einer Antriebswelle (20) zum Antrieb (12) eines Werkzeugs (22) zum Anziehen einer Verschraubung mit einem vorbestimmten Anzugsmoment gekoppelt ist, mit einem Stromsensor (38) zur Erfassung eines Motorstroms (IM), mit einer Steuereinrichtung (36) zur Steuerung des Antriebs (12), wobei zur Abbremsung des Antriebs bei Erreichen eines Bremskriteriums ausgebildet ist, wobei die Steuereinrichtung (36) für die Bestimmung des Abschaltkriteriums auf der Basis des vorbestimmten Anzugsmoments zur Berechnung eines Grenzwertes für den Motorstrom ausgebildet ist, bei Überschreiten dessen der Antrieb (12) in einen Wartezustand versetzt wird, und wobei die Steuereinrichtung (36) für die Bestimmung des Bremskriteriums auf der Basis des vorbestimmten Anzugsmoments zur Berechnung einer Aktivierungszeit oder eines Drehwinkels, bei Überschreiten dessen der Bremsvorgang eingeleitet wird, zumindest in Abhängigkeit von der kinetischen Energie des Antriebs zum Zeitpunkt der Überschreitung des Grenzwertes für den Motorstrom ausgebildet ist, wobei der Elektromotor (14) während des Wartezustands bis zum Einleiten des Bremsvorgangs weiter bestromt wird, gar nicht oder nur teilweise bestromt wird (Fig. 1).
