Aerotech's ASR series direct-drive spindles were designed to provide superior angular positioning and velocity control for applications including disk drive testing, imaging applications, and precision wafer inspection.

Superior Mechanical Design
Matched angular contact bearing sets minimize spindle error motions. In addition, the ASR2000 is balanced to ISO 1940 G 1.0 tolerances. This unique design includes externally accessible balancing screws that can be adjusted with final payload in place. The design also uses labyrinth-type sealing to minimize particle migration from the spindle, resulting in certification for Class 1 clean-room operation. An integral rotary union is provided for a vacuum supply.

Brushless Direct Drive
To maximize positioning performance, the ASR series utilizes Aerotech's brushless motor technology. These motors have all the advantages of a brushless direct-drive motor — no brushes to wear, and high acceleration and 
high speeds. With its low inherent inertia and high torque output, the ASR is capable of extremely high speeds and accelerations. In addition, the efficient electromagnetic design provides high performance with lower operating temperatures than comparable products.

Accurate Positioning
With a velocity ripple of <0.1%, a total radial error motion <3 µm, and total axial error motion <1.5 µm, the Aerotech spindle offers superior performance for high accuracy applications. The high performance motor and 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.

OEM Version for Application Flexibility
For applications requiring integration into a custom machine, an OEM version is available. The OEM version offers all of the same performance characteristics as the standard actuator, but allows the user to eliminate or modify different characteristics of the actuator. For example, the user can provide their own cable management system, choose a different bearing system, or customize the mounting holes. 

Flexible Configurations
Options include mechanical or vacuum chuck configurations. Aerotech manufactures a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package.
