DSM offers custom design capabilities for rotary and linear piezo stages required for unique positioning applications and environments. DSM's flexure mechanism designs are used in micropositioning applications where backlash- and stiction-free performance are critical.
DSM developed a rotary piezoelectric driven actuator for use in the Sandia RAZAR Adaptive Zoom Rifle Scope
A representative example of a custom, multi-axis design required a ±0.25° rotational stage mounted to two manually-adjustable flexure stages for 0.5 mm linear travel and ±2° rotation (not shown). The rotary stage was designed for closed-loop operation using an eddy current proximity displacement sensor and DSM's SA servo amplifier. The total footprint of the assembly is approximately 25 x 60 mm. In the actual closed-loop application, this stage achieved the desired move and settle operation for 10% of the full scale rotation within 10 msec.
