The ACT is a high performance, cost-effective, linear-servomotor-driven actuator that is faster and more accurate
than a ball screw or belt-drive without the costly, time-consuming
maintenance required. Since the ACT is an
integrated, assembled mechanical system, it eliminates the
design complexity and guesswork in choosing and
assembling individual components. The ACT is ideal for
applications including assembly, pick and place machines,
electronic assembly and qualification, packaging, vision
inspection, dispensing, life sciences, image scanning and
processing, and inkjet printing.
Linear Motor Drive
Aerotech’s high-power, cog-free linear motors drive the
ACT series in no load conditions to accelerations of 5 g and
a top speed of 5 m/s, enabling the ideal solution to increase
throughput. The stiff mechanical structure of the actuator
allows for excellent dynamic performance and reduced
settling times. The non-magnetic forcer coil provides high
force with zero cogging for super-smooth velocity and
position control. This zero cogging design is ideal for
applications requiring outstanding contour accuracy and
smooth velocity profiling. As with all Aerotech linear
motor stages, the linear motor has zero backlash, no
windup, zero friction, and outstanding system
responsiveness. The magnetic field of the linear motor is
totally self-contained within the U-channel design. Many
high-performance applications cannot tolerate the stray
magnetic fields generated by flat motor magnet tracks.
High Performance
Noncontact linear optical encoders with micron-level
repeatabilities are standard on all ACT series actuators.
Either a line-driver output or amplified sine-wave output
encoder is available for maximized flexibility. The optional
HALAR factory calibration further increases standard
accuracy and repeatability. Aerotech manufactures a wide
range of matching drives and controls to provide a fully
integrated and optimized motion solution.
High Reliability
The ACT actuators consist of noncontact linear motors and
encoders, making the actuators virtually maintenance-free.
As a result, there is no backlash, windup, wear, or
maintenance that is normally associated with contacting-type
systems such as ball screws or belt drives.
Adjustable Options Maximize Application Flexibility
Multiple cable management options allow flexibility in
design. For applications requiring a complete solution, a
cable management chain is provided. For OEM or
applications requiring user-defined cable management, both
cable pigtail and bulkhead termination options are
available. Moveable limits allow easy adjustment of usable
travel for varying application requirements.
