Zusammenfassung: | The invention relates to a drive unit (01), comprising an oscillator (06) that is drivable by a first actuator (08) to move along a longitudinal axis to generate an oscillating movement, and further comprising a compensator that is drivable by a second actuator along, or parallel to, the longitudinal axis to move in phase opposition to generate a compensating movement. A guide unit guides, in an axially movable manner, the oscillator (06) in a first guide (11) and the compensator (07) in a second guide (13). A position sensor may provide a positioning signal. A control unit controls the first and second actuators (08, 09) to drive the oscillator (06) and the compensator (07). |
