ServoRingTM 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

 

To maximize positioning performance ServoRingTM rotary tables utilizes direct drive three phase ring 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

     

Compact package

 

The design of the ServoRingTM rotary stages was optimized to provide highest torque density in the smallest volume. ServoRing stage has clear center aperture that can be used for air or wire line feed-through or beam delivery

 

Accurate Positioning performance is assured with precision encoder that provides sub arc-sec positioning resolution. The motor and rotary encoders are directly coupled to eliminate coupling backlash.

 

High precision roller bearings for combined axial/radial loads are used to maximize performance with respect to wobble and moment stiffness
