Motion can be free of backlash and friction
Two ultra-compact piezoelectric actuators or stages for weight-sensitive and space-sensitive applications flexure-guided mechanisms that enable motion free of backlash and friction.
The FPA-550-HK offers a mechanism stiffness of 2.5 N/micron to maintain a positioning bandwidth of >30Hz when the actuator is loaded with 125 lb.
Its displacement range is 550 microns and features an unloaded (fixed-free) natural frequency of 340Hz.
With an appropriate displacement feedback signal, the actuator can be used in a closed-loop system to achieve sub-micron positioning resolution and accuracy.
