| 摘要 |
The invention relates to a hand-held power tool having a tool receptacle (2) for accommodating a tool insert (4) along a working axis (11), a motor (5), and a blocking-body coupling (21) having a quantity of blocking bodies. A sensor (27) is used to record a measurement signal (28) as a measure of vibrations within the hand-held power tool (1). A bandpass filter (29) has a passband in which a frequency equal to the product of the rotational speed of the drive-side wheel (22) having the quantity N of the blocking bodies (24) lies. The measurement signal (28) filtered by the bandpass filter (29) is fed to an evaluating unit (30). If a limit value is exceeded by the filtered measurement signal (28), the evaluating unit (30) reduces the rotational speed of the motor (5). |
