| | Dec 26, 2011 — InteliDrives, Inc. (Philadelphia, PA) released new AccuRing series direct-drive rotary stages that provide superior angular positioning and velocity control with exceptionally large apertures.
These rotary stages have zero backlash and no gear wear or gear vibration and are significantly faster than worm and gear drives. User system accuracy and repeatability will be maintained over long time in the systems with AccuRings. Higher accuracy and no backlash allow customers to produce more accurate and consistent products.
AccuRing rotary tables use angular contact bearings to maximize performance with respect to wobble, moment stiffness, and rotating friction. A precision-machined rotating shaft further minimizes wobble.
Positioning accuracy is assured with encoder resolutions up to 0.18 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.
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.
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.
IntelLiDrives, Inc. also offers a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package.
