IntelLiDrives (www.intellidrives.com) has introduced the all-new AccuRing series direct-drive rotary stages that offer superior velocity control and angular positioning with large apertures.

Its large aperture rotary stages deliver zero backlash as well as no gear vibration or gear wear. The new direct drive AccuRings are much faster than gear and worm drives. The stage’s repeatability and system accuracy are maintained over long period of time, while its higher accuracy and zero backlash enables customers to yield more consistent and accurate products.

The new rotary stages are suitable for various applications such as single and multi-axis laser testing, inertial navigation device testing, antenna testing, precision wafer inspection, high-accuracy laser machining and photonic component alignment.

Unlike traditional transmission based rotary tables with the same payload and apertures capacity that can operate to 10rpm or below, the direct drive AccuRing stages can deliver up to 300 rpm continuous rotation.

Its angular contact bearings optimize performance with respect to moment stiffness, wobble and rotating friction. It also features a precision-machined rotating shaft that further reduces wobble.

 

The AccuRing employs brushless modular RotoLinear motor technology to maximize positioning performance. The motor offers all the benefits of a brushless direct drive motor — no gear trains to maintain, no brushes to wear as well as high speeds and high acceleration. This effectively makes the direct drive rotary stages ideally suited for applications that require smooth scan velocity, contoured motion and precise incremental steps.
