Method for detecting a kickback or a breakthrough of a machine tool with an oscillating output movement, device, and machine tool comprising the device

A device for identifying a deflection or a breakdown of a hand-held machine tool configured as a saber saw, jigsaw, or electric handsaw with an oscillating output movement, the device comprising:

• at least one detection unit configured to continuously or periodically detect at least one physical characteristic of an electric motor of the machine tool;
• and
• at least one analysis unit configured to identify the deflection or the breakdown of the machine tool as a function of at least two values, which are detected at different times, of the at least one physical characteristic of the motor,
• wherein the at least two values of the at least one physical characteristic are associated with a respective at least substantially identical value of a discrete position characteristic of the oscillating output movement of the machine tool.
