Method for identifying power tools and kickback events for power tools

The present invention relates to a power tool (10; 20; 30) having a rotary tool (1) formed as a saw blade or milling cutter， the power tool is a sensor device (2) for detecting a mechanical variable (3) and It comprises a control device (4) communicatively connected to the sensor device (2)， wherein the mechanical parameters (3) include force， acceleration， speed， deflection， deformation and / or mechanical stress， and the tool (1) )， And the control device is configured to identify a kickback event based on the detected mechanical variable 3， wherein the control device 4 is selectively based on the function determination information. It is configured to determine a first identification function or a second identification function different from the first identification function， and use the determined identification function to perform kickback event identification based on the detected mechanical variable. The invention relates to an electric tool (10; 20; 30) comprising a rotatable tool (1) embodied as a saw blade or mill， provided with a sensor device (2) for detecting a mechanical variable (3)， the mechanical variable (3) comprising a force， an acceleration， a speed， a deviation， a deformation and/or a mechanical tension， said mechanical variable (3) depending on a force exerted by the tool (1)， said electric tool also comprising a control device (4) that is communicatively coupled to a sensor device (2) and is designed to identify a kickback event on the basis of the detected mechanical variable (3)， the control device (4) being designed to selectively determine， on the basis of function-determining information， a first identification function or a second identification function that is different from the first identification function， and to carry out the identification of the kickback event based on the detected mechanical variable， using the determined identification function.
