Large 335 mm center aperture and lightweight construction makes this rotary stage an ideal choice for processing 300 mm semiconductor wafers.
This stage can be easily installed into IntelLiDrives open frame XY tables.
ACR-335UT rotary actuator has very wide dynamic speed range and can move at sub-rpm speed with very low velocity ripple and accelerate quickly to 3,000 rpm. Its directly coupled precision encoder resolves positions down to 0.25 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-335UT outperform the stability, acceleration and settling speed of 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.
