DSM offers custom design capabilites for rotary and linear piezo stages required for unique positioning applications and environments.  DSM's flexure mechanism designs are used in micropositiong applications where backlash- and sitction-free performance are critical.

 

Custom Piezoelectric Rotary Stages

A representative example of a custom, multi-axis design required a +/-0.25 degree rotational stage mounted to two manually-adjustable flexure stages for 0.5mm linear travel and +/- 2 degree 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.

Custom Piezoelectric (PZT) Rotary stages

Example Features:

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