The ABL2000 combines excellent pitch/yaw characteristics with
the unsurpassed velocity control that is necessary for printing,
imaging, semiconductor, and photonic applications.
Air Bearing Design
By utilizing a magnetic preload, the ABL2000 features a smaller
cross-section than typical air-bearing stages without sacrificing
load capability. The large air-bearing surfaces provide excellent
stiffness, allowing for heavy loading. Proprietary manufacturing
techniques result in a stage with unsurpassed pitch, roll, and
yaw characteristics. Manufactured in Aerotech’s state-of-the-art
production facility, the ABL2000 is machined with exacting tolerances
that are unachievable by conventional methods.
Linear Motor Drive
The driving force behind this stage is Aerotech’s BLMC brushless
linear servomotor. Aerotech’s long history and experience
as a motor manufacturer is reflected in this latest design. The
BLMC utilizes an ironless forcer, which means there is zero cogging
and no attractive forces – resulting in unsurpassed smoothness
of motion. Since the stage is friction-free and the motor has
zero cogging, extremely fine resolutions are achievable.
Zero Maintenance
Our totally noncontact air bearing, noncontact linear motor drive,
and noncontact feedback device ensure years of maintenance-free
operation at the high performance levels that are expected of
Aerotech equipment. Because there is no mechanical contact between
moving elements, the ABL2000 experiences no wear or reduction
in performance over time. Service life is virtually unlimited,
and since there is no lubrication – only clean, dry gas
– air bearings are ideal for cleanroom and medical applications.
Cable Management
Years of research have resulted in what is universally considered
to be the best cable management system (CMS) in the industry.
We carefully optimize the cable bend radius and utilize only the
highest quality cable 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.
To facilitate integration into the final system, we include all
customer-required cables, air hoses, etc. in our CMS bundle. Both
ends are fully connectorized for simple integration into the customer’s
machine. High flex ribbon cable versions are also available.
