Product Name: Spindles ABS2000

Product Description

Aerotech’s ABS series direct-drive air-bearing 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 The ABS2000 is balanced to ISO 1940 G 0.4 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. Low Loss, Non-Influencing Direct-Drive Motor Aerotech’s custom designed, low-loss motor produces >0.25 N-m (38 oz-in) of continuous torque, with negligible motor losses, eliminating the need for cooling fins and/or external cooling. The non-influencing motor design minimizes parasitic forces in the motor, providing the exceptionally high level of error motion performance. 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 ABS is capable of extremely high speeds and accelerations. Accurate Positioning With a velocity ripple of <0.1%, an asynchronous error motion <20 nm, and total error motion <100 nm, the Aerotech spindle offers superior performance for high accuracy applications. The high performance motor and rotary encoder are directly coupled to a common shaft. When used with the Aerotech A3200 controller and Npaq® drive rack the spindle resolution can be as high as 0.05 arc sec with no speed trade-offs. This makes the spindle ideal for applications requiring both spindle operation and stage operation. Flexible Configurations Options include mechanical or vacuum chuck configurations, grounding ball, and optics mounting. Alternate higher torque motors are available. Aerotech manufactures a wide range of servo amplifiers and advanced controllers to provide a complete, integrated motion package.
