Aerotech: Linear Motor Drive Precision Stage (ABL1500WB Series)

Linear Stages

Aerotech manufactures a large selection of positioning stages including linear stage models that utilize our own brushless linear direct-drive servomotors, as well as ball-screw models driven with Aerotech brush or brushless rotary motors. Innovators in linear stage design, manufacture and integration, Aerotech builds linear positioning stages for high-performance applications in industrial robots, fiber optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, laser micromachining, electronic manufacturing, and other industrial automation applications.

Aerotech linear stages are available in X, XY and XYZ combinations to meet your motion requirements.

ABL1500WB Air-Bearing Direct-Drive Linear Stage

Design Features

The ABL1500WB is a wide-base version of the ABL1500 series air-bearing stage. The wider base makes the ABL1500WB ideally suited for applications with large offset loads, and it is ideal as the lower axis in XY stage systems with large travel. The ABL1500WB incorporates dual linear motors, effectively doubling the force output of a standard ABL1500 stage.

Leading-edge industries, particularly in the semiconductor and high-performance test and measurement fields, demand positioning tolerances beyond the capability of conventional ball-screw and mechanical-bearing positioning systems. The ABL1500WB, with its fully active preload, exceptionally high stiffness, and excellent geometric characteristics was designed specifically to meet those demands.

Air-Bearing Design for High Dynamic Performance

The ABL1500WB incorporates an air-on-air preload on both the vertical and horizontal surfaces. The opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air-bearing surface that distributes the load over a large surface area, results in a stage with outstanding stiffness that is ideal for heavy or offset loading.

Aerotech’s proprietary manufacturing techniques result in a stage with unsurpassed geometric characteristics, which maximize performance by yielding superior pitch, roll, yaw, straightness and flatness specifications.

Linear Motor Drive

The driving force behind this stage is Aerotech’s BLMC series brushless linear servomotor. The BLMC utilizes an ironless forcer, which means there is zero cogging and no attractive forces, resulting in unsurpassed smoothness of motion.

Zero Maintenance

Our totally non-contact air bearing, non-contact linear motor drive and non-contact feedback device ensure years of maintenance-free operation at the high performance levels expected of Aerotech equipment. Because there is no mechanical contact between moving elements, the ABL1500WB experiences no wear or reduction in performance over time. Service life is virtually unlimited and because there is no lubrication – only clean, dry gas– air bearings are ideal for cleanroom and medical applications.

Cable Management

We carefully optimize the cable bend radius to ensure years of trouble-free operation. In the unlikely event of failure, Aerotech’s modular design makes cable replacement quick and easy with minimal downtime.

We include all customer-required cables, air hoses, etc. in our CMS bundle to facilitate integration into the final system. Both ends are fully connectorized for simple integration into the customer’s machine.
