Abstract (en)
The power tool (10) can be an angle grinder with a housing (12) accommodating a transmission unit (14), an electric drive (24), and an electronic module (28). Two vibration absorbing elements (30,31) are positioned at the housing (12) in the transition area between the motor (24) and the transmission unit (14). A second pair (32,33) is located between the motor (24) and the electronic unit (28). The vibrations created by the device (10) are transmitted from sensors integrated in the vibration absorbing elements (30,31,32,33) to a microprocessor and returned as a dephased control signal.
