ELECTRIC POWER TOOL AND METHOD FOR OPERATING SAME
First Claim
Patent Images
1. A method for operating an electric power tool, comprising the steps of reacting by a torque limitation of an electric motor when a load moment exceeds a predetermined threshold;
- carrying out an output request by a switch;
interrupting a supply of current to the electric motor in at least partially automatic fashion when a criterion for a reaction of the torque limitation is detected.

Abstract
In an electric power tool and a method for operating an electric power tool, a torque limitation of an electric motor reacts when a load moment exceeds a predetermined threshold and in which an output request is carried out by means of a switch. A supply of current to the motor is interrupted when a criterion for the reaction of the torque limitation is detected based on a speed detection of the motor.
