Aerotech AVL1000 Mechanical-Bearing Direct-Drive Lift Stage

AVL1000 Mechanical-Bearing Direct-Drive Lift Stage

Our AVL1000 represents a significant breakthrough for applications that

require Z articulation for large payloads, like flat panel display processing.

Multi-axis systems with high load inertia can suffer from mechanical

stability problems that limit total machine throughput.

The AVL1000’s proprietary design significantly increases stage stiffness

to eliminate this problem.

Design Features

• High load-carrying capability

• High stiffness

• Noncontact direct-drive

• High accuracy

• Integral pneumatic counterbalance

• Easily configured with ARA1000 for multi-axis applications

The AVL1000 has a wide footprint that increases stiffness by separating the

bearing elements as far as possible. This design also incorporates mechanical

elements that fully constrain the carriage and virtually eliminate undesired motion.

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-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.
