Mounting Guidelines for PZT Translators
 


Adherence to the following guidelines will help you obtain maximum performance and lifetime from your PZT actuators:

I.PZT stack actuators must only be stressed axially. Tilting and shearing forces can be avoided by use of ball tips, flexible tips, etc.

II.PZTs without internal preload are sensitive to pulling forces. An external preload is recommended for applications requiring strong pulling forces (dynamic operation, heavy loads, etc.).

III.Maximum torque allowable at the top-piece can be found in the technical data tables for all PZT stacks and must not be exceeded. Proper use of wrench flats to apply a counter-torque to the top-piece when a mating piece is installed will protect the ceramics.

IV.When PZTs are installed between plates, a ball tip is recommended to avoid bending and shear forces.

Summary
Piezoelectric actuators offer today's motion engineer a practical way to achieve extremely high positioning accuracy in a wide variety of applications. Examples given in this discussion indicate but a few of the many applications of piezo actuators. In the near future, PZT-based motion will more and more replace classical motion systems. In addition, the unique features of PZTs will trigger development of products that could not exist without this technology and help push back the frontiers of miniaturization, precision and throughput.
