  • Publication number: 20120103643
    Abstract: A control method for a power tool and a power tool is disclosed. The control method has an operating mode and a safety mode. In the operating mode, a motor drives a tool receptacle in a rotating manner. In the operating mode, the motor has a power consumption in the amount of at least an operating value. The safety mode is triggered if a sensor device detects a rotational blockade of the tool receptacle. In the safety mode, a clutch that is switchable by electrical signals located in the drive train between the motor and tool receptacle is periodically opened and closed and a power consumption of the motor is reduced as compared to the operating value.

  • Publication number: 20110162860
    Abstract: A hand-operated rotary power tool and a method of operating the tool is disclosed. The tool has an electric motor for driving a rotary tool, a sensor device for detecting a blockade of the tool and a triggering device, which, in response to a blockade detected by the sensor device, reverses a direction of rotation of the electric motor prior to the blockade for a predetermined duration and immediately following induces the electric motor to again rotate in the direction of rotation.

  • Publication number: 20100263890
    Abstract: A control method according for an impact wrench includes ascertaining whether the impact wrench applies an impact when the drive shaft rotates in a lower speed range. The speed of the drive shaft then is increased to a higher speed range as a function of an ascertained impact during the rotation in the lower speed range.
