PDR110 Rotary Stage from Primatics

Primatics PDR110 Rotary StageThe Primatics PDR110 rotary stage is designed for applications requiring full continuous rotation with precise positioning and smooth motion control. Unlike limited-angle rotary stages, the PDR110 offers unrestricted 360° movement, making it ideal for processes that depend on repetitive or uninterrupted rotational motion.

Powered by a direct-drive brushless servo motor, the PDR110 eliminates mechanical gearing, reducing backlash and minimizing wear over time. This architecture provides smoother motion profiles, faster response times, and greater long-term reliability.

Its compact footprint and rigid mechanical design make it well-suited for automation platforms, inspection systems, and optical applications where rotational accuracy directly impacts performance.

Typical Applications:

  • Continuous optical scanning
  • Semiconductor wafer handling
  • Laser beam steering
  • Automated inspection systems
  • Rotary indexing applications
  • Precision assembly platforms

Q & A

PDR110 Rotary Stage Q & A

+What is the difference between the Primatics PDR110 and PLR110?
The PDR110 supports continuous full rotation, while the PLR110 is designed for limited-angle positioning. If your application requires uninterrupted rotational movement, the PDR110 is the better fit.
+Is the PDR110 suitable for indexing applications?
Yes. Its direct-drive architecture and repeatable positioning make it an excellent choice for high-speed indexing and repetitive rotary positioning.
+Does the PDR110 have backlash?
Because it uses direct-drive technology instead of gears, backlash is significantly minimized compared to traditional gear-driven rotary stages.
+Can the PDR110 be used in semiconductor environments?
Yes. Its cleanroom-compatible design and precision motion performance make it suitable for semiconductor handling, inspection, and alignment systems.
+What should I consider when selecting the PDR110?
Important factors include payload weight, required rotational speed, duty cycle, positioning accuracy, and whether your application requires continuous or limited-angle movement.
