Aerotech AVS1000 Mechanical-Bearing Ball-Screw Lift Stage

Our AVS1000 series stages offer the ideal solution for applications that

require moving large or heavy loads over very small incremental

movements in elevation above a horizontal plane. Low profiles and

precise motion capability make these stages ideal for use in

semiconductor manufacturing and inspection, automated tool alignment,

machine vision inspection systems and laser machining applications.

Design Features

• High-load lift stage with aperture

• Submicron closed-loop positioning

• Excellent pitch and yaw characteristics over full travel

• 5 mm or 10 mm travel; custom designs for alternate travels available

• Optional cleanroom and ESD protection

• Precision-ground ball screw for high performance

• Quality Design Provides Superior Performance

The AVS1000 series provides precise elevation of a load in a vertical plane

using a moving wedge design. The precision machined wedge block

converts horizontal movement from a precision-ground ball screw to

vertical elevation of the AVS1000 series tabletop.

Sealed linear motion guide bearings with integral wipers are incorporated

to provide excellent payload capability, long life and smooth, precision

motion. Stable and parallel vertical motion with no rocking or horizontal

deviation of the platform is ensured.

Careful design of the wedge angle and bearing system allows the AVS1000

series to achieve submicron resolution and still maintain a compact profile.

The optional factory calibration option is available to further increase standard

accuracy and repeatability.

A Better Approach to Vertical Motion

The vertical lift approach offers an alternative to traditional Z-plane oriented

stages. Not only do the AVS1000 series stages offer a lower profile, but the

load can also be accessed easily from any side. And by centering the payload

over the bearings, there are no cantilevering effects.

Motor and Drives

The AVS1000 series includes Aerotech’s high performance NEMA 34 frame-size

BMS series brushless, slotless servomotor. The slotless motor has zero cogging

and therefore is optimized for applications requiring very smooth motion.

Aerotech manufactures a wide range of matching drives and controls to provide

a fully integrated and optimized motion solution.
