Ultra-thin Direct Drive Rotary Servo Indexer

Featured Product from IntelLiDrives, Inc.


IntelLiDrives, Inc. released Ultra-thin rotary table model ACR-160UT that features lowest profile direct drive on the market.

This rotary actuator has 160 mm center aperture for applications in semiconductor manufacturing equipment, wafer inspection and cutting, fiber-optics alignment, optical applications, precision part indexing and robotics. Rotary table ACR-55UT is capable of wide range of rotation speeds from 0,1 rpm to 1,000 rpm with velocity ripple under 0.1%

Rotary table ACR160UT utilizes slot-less direct drive brushless modular motor technology 
for low velocity ripple. Motor rotor is directly coupled to precision rotary encoder with positioning resolution 0.25 arc-sec and absolute rotational accuracy of 5 arc-sec.

ACR-160UT low rotor profile and high torque to inertia ratio allows high rate start-stop motions with exceptionally short settling times to outperform traditional servo motor direct drives and gear-driven mechanisms, which makes ACR-55UT ideal for the applications requiring contoured motion, smooth scan velocity and precise incremental steps.

Bearings with low run-outs are used to maximize performance with respect to wobble, moment stiffness and rotating friction. A precision ground top rotor further minimizes wobble.

Rotary table ACR-160UT can be combined with other IntelLiDrives rotary tables for multi-axes rotational systems.

Matching motor controller with RS-232, USB, CAN-bus and Ethernet interfaces is available for seamless integration.
