avl1000Aerotech’s AVL1000 represents a significant breakthrough for applications such as flat panel display processing that require Z articulation for large payloads. Multi-axis systems with high load inertia can suffer from mechanical stability problems that limit total machine throughput. The AVL1000 eliminates this problem through a proprietary design that significantly increases stage stiffness.

Overview

Superior Mechanical Design

The AVL1000 utilizes a wedge design mounted on high-stiffness bearings to achieve high lateral and rotational rigidity. All elements of the AVL1000 were selected to operate in a 24/7 industrial environment and, unlike screw- or piezo-based vertical stages, the AVL1000 requires no maintenance and will ensure years of trouble-free operation.

Brushless Direct-Drive

To maximize positioning performance, the AVL1000 uses Aerotech’s BLM series brushless, slotless linear motor. This motor has all of the advantages of a brushless direct-drive motor — no brushes to wear, no gear trains to maintain and high acceleration and high speeds. The AVL1000 is ideal for high-bandwidth autofocus applications because the motor produces no cogging force

High Accuracy

Positioning performance is assured by using a precision linear encoder that results in 0.5 nm resolution. The motor and encoder are directly coupled together, increasing the accuracy of the stage by eliminating mechanical hysteresis.

Flexible Configurations

Aerotech also manufactures a wide range of servo amplifiers, advanced controllers, as well as a full line of complementary stage systems to provide a complete, integrated package.
