Abstract (en)
[origin: DE19824495A1] The invention relates to a method for driving an electric screwing device during which a control device supplies electric current in the form of pulse signals to an electric motor. In addition, the motor generates a torque which turns a screwing tool with a rotational speed for driving a screw. In order to relieve a device operator from the burdensome support of the reaction moment as greatly as possible, the invention provides that the interpulse period between two pulse signals is determined in such a way that the rotational speed of the motor during the interpulse period is significantly reduced.
