Primatics PDR Rotary Stages are among the most advanced direct drive tables available. They features a high performance direct drive motor that provides arc-second repeatability and fast settling times making them ideal for semiconductor wafer inspection, high speed laser machining and precision metrology. Their compact design also yields a smaller footprint than comparable worm drives. All PDR rotary stages offer clean room options.
PDR Rotary Stages incorporate a high pole count brushless servo motor which provides low velocity ripple even at low speeds. The high resolution glass disk optical encoder mounted directly to the rotating platen yields arc-second resolution.
A single electrical cable affixed to the stage simplifies integration and cable management. The over-sized cross roller bearing supports the rotating platform, delivering high load capacity, excellent rigidity and long life. A large center aperture allows a convenient routing of hoses or cables to the attached payload.
Direct drive technology eliminates the backlash and wear found in mechanical drives such as worm gears. The direct connection of the motor and high resolution encoder provide high servo stiffness and response. These features combine to make the PDR Rotary Stages an ideal choice for inspection and measuring applications found in many markets.
