DIRECT DRIVE ROTARY TABLES SRT SERIES Key features: Direct drive Large center aperture Brushless motor design Precision bearing system Integrated position feedback Built-in thermal sensors ServoRing rotary tables provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives. Low maintenance and high throughput characteristics of the ServoRing Stage yields the lowest total cost of ownership. Compact package, Superior design The design of the ServoRing rotary stages was optimized to minimize stage height. The low profile of the stage reduces total system working height. Angular contact bearings are used to maximize performance with respect to wobble, moment stiffness and friction. ServoRing stage has large clear center aperture that can be used for air or wire line feed-through or beam delivery Brushless Direct Drive To maximize positioning performance ServoRing utilizes direct drive three phase planar brushless motor technology. There are no brushes to replace and no gear trains or belts to maintain. Lo-Cog magnetic design assures smooth rotation and dynamic performance. Accurate Positioning Performance is assured with high resolution encoder that results in sub arc-sec positioning resolution. The motor and rotary encoders are directly coupled to eliminate coupling backlash. The low inertia and zero backlash make ServoRing the ideal solution for applications requiring frequent directional changes. Applications: Semiconductor assembly Precision machine tools Wafer processing Electronics assembly Robotic handlers Automation
