Abstract

Es wird ein Schrauber (10) mit Drehzahlregelung angegeben, mit einem Motor (18) zum Antrieb einer Werkzeugantriebswelle (24), mit einer Regeleinrichtung (30), mittels der die Drehzahl des Motors (18) regelbar ist, wobei die Regeleinrichtung (30) zur Herabsetzung der Drehzahl n bei Erreichen eines Trigger-Parameters (Tpn) ausgebildet ist, wobei als Trigger-Parameter (Tpn) zur Herabsetzung der Drehzahl (n) ein von der Drehzahl (n) abgeleiteter Wert verwendet wird.

Figure imgaf001
A screwdriver (10) with speed control is specified, with a motor (18) for driving a tool drive shaft (24), with a control device (30) by means of which the speed of the motor (18) can be regulated, wherein the control device (30) is designed to reduce the speed n upon reaching a trigger parameter (Tpn), wherein as a trigger parameter (Tpn) for reducing the speed (n) from the speed (n) derived value is used.
