May 1, 2013 - IntelLiDrives announces ACR-55UT high-speed direct-drive rotary servo motor. This rotary stage has very wide dynamic speed range and can move at sub-rpm speed with very low velocity ripple and accelerate quickly to 1,000 rpm. Its directly coupled precision optical encoder resolves positions down to 0.5 arc-sec, providing lag-free, backlash-free feedback to the servo controller. The rotor low inertia improves the start/stop behavior and velocity control significantly compared to conventional rotation stages, due to the light-weight direct-drive core-less motor.
The result is precise bidirectional speed and position control, which is critical for high speed motion contouring. These features make the ACR-55UT outperform the stability, acceleration and settling speed of the company's traditional servo motor gear-driven mechanisms. Precision four-point preloaded contact bearings are used to maximize performance with respect to wobble, moment stiffness, and rotating friction. A precision-machined rotating shaft further minimizes wobble. IntelLiDrives offers a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package
