Description

Design Features •Low-loss brushless servomotor •Instrument-grade precision •Noncontact air-bearing •Balanced to ISO 1940 G 0.4 •Sub-arc second resolution at high speed •Custom configurations available •Ideally suited for data storage, wafer processing, diamond turning, and imaging Aerotech’s ABS series direct-drive air-bearing spindles were designed to provide superior angular positioning and velocity control for applications including data storage, wafer processing, diamond turning, and imaging. Superior Mechanical Design The ABS2000 utilizes a precision ground air-bearing to provide exceptional rotational accuracy with an extremely high stiffness. This design allows for a large load capacity and superior performance over a wide range of operation speeds. The ABS2000 is balanced to ISO 1940 G 0.4 tolerances. 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.
