DSM's NA-25 and NA-80 actuators manufacturers are direct-drive piezoelectric actuators integrated into a protective metallic frame. The frame is a monolithic piece of stainless steel or titanium alloy with a flexure-based expansion component.
The flexure minimizes the resistance that the frame might impart to the piezoelectric actuation. The frame also includes standard threaded receiver holes at the top and bottom and incorporates a preload mechanism. The mechanical preload maintains compression on the piezoelectric ceramic under high tensile forces and ensures bidirectional operation. The design thus provides increased resilience to mechanical loads when compared to non-preloaded actuators.
The NA-25 and NA 80 are well-suited to many applications where high force and high frequency response are required.
Equipment using the piezoelectric effect of PZT based ceramic elements can achieve unlimited high resolution positioning. piezosystem jena is one of the world leading companies in this technology. An electric field is applied to the ceramic by controlling analog voltage signals.
This results in a change in length of the bi-polar elements depending on the signal strength. piezosystem jena makes use of this effect for the design of positioning equipment with nearly unlimited high resolution. The increased in the length of the PZT is quite small.
Therefore piezosystem jena employs sophisticated flexure hinge designs in order to enlarge the motion up to the mm range. The unique nano-positioning elements of piezosystem jena guarantee the highest resolution in the sub-nm range even when the total travel range is in mm.

DSM's FPA-80E Mini is a flexure-guided piezoelectric cylinder ideal for both dynamic and static applications where precise and accurate positioning is required. The FPA-80E Mini is mechanically preloaded to ensure bidirectional operation, providing increased resilience to mechanical loads when compared to non-preloaded manufacturers of actuators. The kinematic mechanism provides high-stroke operation in an exceptionally small package.
The FPA-80E Mini’s compact design is well suited to many applications and comes standard in a durable, non-corrosive stainless steel design pre-tapped with threaded mounting holes to match a customer’s requirements.
DSM’s FlexFrame PiezoActuator(TM) series is a family of mechanically amplified, flexure-guided piezo supplier of actuators for precision motion control and positioning applications. The actuators feature solid-state flexure professional hinges to eliminate backlash and stiction.
Standard piezo actuator designs offer displacement capabilities ranging from a few microns up to 2 mm, and the actuators typically feature low voltage (150-200V) piezo material. Custom designs can be produced for unique displacement ranges, design stiffness, and environmental considerations (temperature, vacuum, non-magnetic, etc.), DSM's piezo actuators can also be configured with integrated displacement feedback sensors for closed-loop micropositioning and nanopositioning.
DSM's FlexFrame PiezoActuator(TM) design allows for high displacement performance in an extremely low profile package. Custom mounting conditions can be integrated into the design.
DSM welcomes custom requests for flexure-guided piezo actuator designs. Please consider the following questions and contact us:
* What displacement range is required?
* What load will the actuator carry? Is it a static load or a dynamic load such as a spring force?
* What positioning resolution and accuracy are required?
* How fast does the actuator need to move, or at what frequency will you drive the actuator?
* What does the desired motion profile look like? (point-to-point, sinusoidal, etc.)
* Are you able to use open loop operation, or do you require closed-loop servo control?
* Are there any special environmental considerations (temperature, humidity, vacuum, etc.)?
* What are the geometric constraints for the actuator or stage?
