Most of the piezo actuators and stages DSM makes don't show up on the website.
LFPAs and LPAs can be configured to expand or contract when energized. The combination of two amplification stages can provide a large nominal travel value up to 10 mm in a mechanical volume less than 20 x 50 x 100 mm. LPAs can have a two-stage amplification mechanism as in the Lever-amplified Flextensional Piezo Actuator (LFPA). It also offers access to both sides of the stack, which allows creative enhancements such as the addition of a radiation shield or additional sensors.
#PIEZO ACTUATORS SERIES#
The LPA series has clear access to both sides of the actuator output, which can be beneficial. With less moving mass, the actuator output resonant frequency may be higher than a comparable FPA actuator. Using the simple lever geometry, the output arm may be designed with a lower moving mass than other amplified actuator types. Using a simple design geometry of a classic lever and fulcrum, the piezo stack provides the applied force or displacement to move the output load. Lever-amplified piezo actuators (LPAs) may have a higher natural frequency than a Flextensional Piezo Actuator (FPA).
Lever-Amplified Piezo Actuator (LFPA and LPA) Simple lever mechanism lowers moving mass to promote higher resonant frequency. Composite frame materials can be implemented where weight savings is crucial. Piezo actuators can be used for cryogenic and vacuum applications. Piezo actuator flexure-frames can be made from nonmagnetic materials for high magnetic field applications. When applications require significant loading in the same direction of travel, DSM may customize the actuator design with additional preload elements. If loading has the potential to drive the endcaps away from the piezo stack (e.g., when the FPA is "overloaded" in the direction of its designed travel instead of opposite), the preload holds the piezo stack in contact with the actuator frame. The preload level is carefully designed to limit the potential for the endcaps to separate from the piezo stack under allowable operating conditions. The preload bands in DSM’s actuators especially enhance the actuators ability to carry compressive and tensile loading. DSM’s range of FPAs offers a wide selection of open-loop displacement, stiffness, blocking force and resonant frequency. In double-arm construction, the extra set of arms reduces the potential for output block rotation. FPA geometry is available in single-arm or double-arm construction to provide additional output guidance stability.
