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.

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.
