PDR Series Precision Direct Drive Rotary Tables

Primatics PDR rotary tables are among the most advanced direct drive tables available. They feature a high performance direct drive motor that creates sub arc-second repeatability and fast settling times, making the PDR series ideal for semiconductor wafer inspection, high speed laser machining & precision metrology. The compact design also has a smaller footprint than comparable worm drives

• Direct drive continuous rotary motion
• Space saving, compact design, the PDR is among the most compact direct drive stage on the market.
• 110-210 mm diameter model's
• Low maintenance & longer life; integrated brushless servo direct drive motor eliminates gear wear, backlash and torque variation associated with worm drive and belt driven stages.
• High pole count aids in obtaining low velocity ripple.
• Resolutions to 0.18 arc-seconds
• Clean design; all multiplication electronics are internal and there is only one cable necessary for external connections.
• Class 10 cleanroom option
