压电陶瓷芯片 | PCh 150 / HPCh 150
PCh 150 / HPCh 150压电陶瓷芯片多层压电陶瓷组成最大推力可高达10000N，这些驱动器可以精密移动，产生的自由行程范围(无负载条件下)从2 µm至4 µm 。驱动器预载最大位移负载时，可以达到最大位移，每种型号对于这点都有相应规定。每种型号最大位移的实际值有所差异，必须通过实验确定，最大位移始终会大于自由行程位移。

1) direction of expansion
2) semi-bipolar/unipolar activation
3) blocking force = max. force generation defined for max. semi-bipolar operation
Dimensions
a, b, L
tolerances:
a, b +/- 0.3 mm
L +/- 0.1 mm
Fig. : Piezo-chips PCh, PHCh
Mounting advises: Piezo-chips show very small stroke rates due to their short active length L.
Incorrect mounting will impact force and stroke generation, leading to insufficient performance and unwanted bending and tilting. Please follow instructions in chapter 2.3.
