Custom Stages

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.

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
