Piezo Stack Handling and Operation
The coupling of piezo-actuators to guided non-floating mechanisms can result in one of the most widespread design mistakes: coupling a flat faced actuator directly to a flat faced guided mechanism. Even the slightest misalignment between the orientations of the both planes leads immediately to edge squeezing with very high local spot pressures and subsequent ceramic damaging, especially under high force loaded conditions.
Coupling Considerations
- High Pressures Can Lead to Damage
- Design Systems with Floating Axis When Appropriate
- Use Available or Custom End Pieces
- Axialy Acting Stacks Also Require Care
- Consider the Whole System Both During Setup and Operation

Interesting Options from TQ Electronics
APPLICATION RESOURCES
AWG units provide comprehensive waveform selection directly coupled with state-of-the-art switch-mode power drive technology. The AWG Graphical User Interface enables the user to create a wide array of selectable wave shapes from either the built-in library or user-defined arbitrary waveforms.
PTD units provide real-time track/follow ability for output phase between voltage and current that is now entirely programmable. The introduction of programmable tracking provides users with an increased level of changeability in design and test of design variables.
PDAC units are capable of driving highly reactive loads (such as piezoelectric devices) at very high efficiency levels as to provide a rapid prototyping tool into the laboratory. PDAC technology provides high peak current capability for driving electrical systems that require extremely high initial, instantaneous current to begin moving and then a lower, continuous current to remain in place.
