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 |
