Custom Piezoelectric Rotary Stages

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.

Example Features:

  • Flexure-based for smooth, backlash-free motion
  • 35 mm assembly height (18 mm height without the ±2° tilt stage, not shown)
  • 25 mm x 60 mm footprint
  • Stiff construction for fast servo positioning
  • Scalable design for larger or smaller motions
