Handheld power tool

A handheld power tool comprising:

• a tool holder for holding a tool;
• an electric motor;
• a shaft connecting the tool holder and the electric motor;
• and
• a protective device for stopping the tool holder in an uncontrolled situation, the protective device including:
• a sensor for detecting the uncontrolled situation;
• a switchable current source outputting a first current not equal to zero in response to signals of the sensor if an uncontrolled situation is not detected and not outputting a current or outputting a second current different from the first current if an uncontrolled situation is detected;
• and
• a normally closing magnetic brake for engaging on the shaft and not applying a torque to the shaft when energized by the first current and applying a torque counteracting the rotational movement of the shaft when not energized or when energized by the second current;
• wherein the magnetic brake includes a stationary brake shoe and a brake disk movable relative to the brake shoe around the axis of the shaft and along the shaft and wherein the magnetic brake further includes a permanent magnet and a solenoid coil, a permanent magnetic field generated by the permanent magnet and a magnetic field generated by the solenoid coil, through which the first current flows, being antiparallel, and wherein the brake shoe and the permanent magnet are situated in a closing direction of the brake disk.
