safety tool for portable tool with thermal motor allowing almost instantaneous shutdown of the operation of said tool, and portable tool with thermal motor
The device has a three-axis electronic accelerometer (5) measuring an acceleration along three axes (X-Z), and including an output connected to an electronic and/or electrical control unit constituted of an electronic and/or electrical brake control card (7). The control unit and the accelerometer are supplied with electrical voltage by a self electric current generator i.e. magnetic hand wheel (9). The control card processes analog or digital electrical information issued from the accelerometer and activates a unit assuring quasi instantaneous stop of a thermal motor.
