Applications for the AccuRings
include single and multi-axis laser testing, antenna testing,
inertial navigation device testing, photonic component alignment,
high-accuracy laser machining and precision wafer inspection. These
rotary stages can also be configured as multi-axis gimbals.
High Speed
Conventional transmission based rotary tables with similar apertures and
payload capacity operate only to 10 rpm or less. AccuRing
direct-drive stages have been tested to 800 rpm continuous rotation.
Superior
Mechanical Design
Angular contact bearings are used to maximize performance with
respect to wobble, moment stiffness, and rotating friction. A
precision-machined rotating shaft further minimizes wobble.
Brushless Direct-Drive
To maximize positioning performance, AccuRing Series direct-drive
rotary stages utilizes brushless modular RotoLinear motor
technology. This motor has all of the advantages of a brushless
direct drive motor – no brushes to wear, no gear trains to maintain,
and high acceleration and high speeds. This makes the AccuRings
ideal for the applications requiring contoured motion,
smooth scan velocity and precise incremental steps.
Accurate Positioning
Performance is assured with encoder resolutions up to 0.16 arc sec.
The motor and ring encoder are directly coupled to a rotating shaft.
The absence of gear trains and mechanical couplings eliminates
position errors caused by hysteresis, windup or backlash. As a
result, accuracy of 5 arc sec and bi-directional repeatability of
0.5 arc sec are attainable.
Flexible Configurations
IntelLiDrives offers a wide range of servo amplifiers and advanced
controllers to provide a complete, integrated package.
