Piezoelectric linear motor comprising a group of piezostack actuators and its method of operation

摘要

The piezo linear drive has a group of piezo stack actuators, where an arrangement of the actuators is provided with a two-pole wiring, which is partially formed by an electrode arrangement bridging a continuous separation column and running between the stack parts. The actuators are stacked corresponding to clamping and feed movements to be performed alternately in parallel or antiparallel to the polarization direction of the electrode.
