Aerotech’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.
- High load-carrying capability
- High stiffness
- Noncontact direct-drive

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.
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
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.
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.
