                High torque output, direct-drive brushless servomotor
                Cog-free design for outstanding velocity stability
                Outstanding wobble and runout
                Direct coupled, high-accuracy rotary encoder
                Large diameter clear aperture

                 

                Aerotech’s ADRT series direct-drive rotary stages provide superior angular positioning and velocity control. Applications range from indexing to high-speed laser machining to precision wafer inspection.

                Superior Mechanical Design
                Dual large-diameter bearings are used to maximize performance with respect to wobble, moment stiffness, and repeatability. The large diameter bearings permit large payloads without compromising performance.

                Brushless Direct Drive
                To maximize positioning performance, the ADRT series utilizes Aerotech’s S-series brushless, slotless motor. This motor has all the advantages of a brushless direct-drive motor – no brushes to wear, no gear trains to maintain, and high acceleration and high speeds. Since it is a slotless, ironless design, there is zero cogging, meaning that there is absolutely no torque ripple.

                With its low inherent inertia and optimized motor design, the ADRT is capable of speeds and accelerations that are significantly higher than other competing products. These stages have a lower height profile compared to competing products within given torque ranges.

                The low inertia and zero backlash make the ADRT the ideal solution for applications requiring frequent directional changes.

                Accurate Positioning
                Line counts range from 3600 to 5400 lines per revolution. When coupled with Aerotech’s MXH series resolution multipliers, resolutions can be as fine as 0.12 arc sec.

                The motor and high-performance rotary encoder are directly coupled to a common shaft. The absence of gear trains and mechanical couplings means no position errors caused by hysteresis, windup, or backlash.

                Flexible Configurations
                Options include a high-precision bearing for improved accuracy, smoothness, and run-out performance. Slip rings and rotary unions are available to ease integration of custom tooling, and a holding brake is available to limit movement of the stage during large impulse loads or when power is removed from the motor.

                The ADRT is the only rotary table available with integrated “T-slots.” These slots can be used to mount the table horizontally or to attach custom application specific fixtures.

                Aerotech manufactures a wide range of servo amplifiers and advanced controllers to provide a complete integrated package.

                Notes:
                1. -P accuracy requires calibration and Aerotech controls.
                2. Specifications are for single-axis systems. Performance of multi-axis systems is payload and workpoint dependent. Consult factory for multi-axis or non-standard applications.
                3. Moment load based on 5 year continuous rotation at 250 rpm with maximum axial load applied. Larger moment loads possible for low speed and/or low duty cycle applications. Consult Aerotech for additional information.
