Weed whacker, has control unit operating electrical drive motor in idle operation after one of operating curves and in loading condition after another operating curve, where operating curves are assigned to control unit

摘要

The whacker has a drive shaft (4) driven by an electrical drive motor (2), where the drive motor is provided with a control unit (20). A pair of operating curves is assigned to the control unit, and the control unit operates the electrical drive motor in an idle operation after one of the operating curves and in the loading condition after another operating curve. An output signal of a sound receiver (28) is monitored, where the switching between the operating curves takes place depending on the output signal.
