Description

Design Features •High-speed brushless servomotor •Instrument-grade precision •ABEC-7 angular contact bearings •Balanced to ISO 1940 G 1.0 •High acceleration capability (6000 rpm in < 1 second) •Custom configurations available 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 labyrinthtype 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.
