PL0xx/PDxxx Piezo Actuator
5.5
Applying the Load
The PL0xx/PDxxx can be coupled to a load in various ways, depending on the application:
Gluing the piezo actuator (p. 26) into the mechanical system to be moved or into a
flexure
Using a ball tip:
−
A hardened ball tip is glued to the ceramic end surface of the actuator; the ball tip
makes contact to the even surface at a single point
−
A hardened ball tip is glued to the ceramic end surface of the actuator; the contact
area at the calotte is circular
INFORMATION
Diagrams showing how to couple the PL0xx/PDxxx to a load can be found in "General Notes on
Installation" (p. 17).
Requirements
You have read and understood the general notes on installation (p. 17).
The PL0xx/PDxxx is discharged (p. 40) and short-circuited (p. 41).
Tools and accessories
Suitable adhesive (e.g., cold-hardening epoxy resin adhesive)
When using a ball tip: Suitable ball tip
When using a flexure: Suitable flexure
Applying the load
Apply the load evenly.
If the piezo actuator is coupled in a milling pocket:
Ensure that there is full-area contact at the end surface of the piezo actuator. For this
purpose, choose the dimensions of the milling pocket correspondingly or make free
cuts in the milling pocket.
If a point load is applied to the end piece of the piezo actuator:
Dimension the end piece so that its thickness corresponds to half the cross-sectional
dimension in order to prevent tensile stresses on the piezo actuator.
