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 ball screw
or belt-drives require. Because the ACT is an integrated, assembled mechanical
system, it also 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.
Aerotech’s high-power, cog-free linear motors drive the ACT
series to accelerations of 5 g and a top speed of 5 m/s, providing the ideal
solution to increase throughput. The stiff mechanical structure gives excellent
dynamic performance and reduces settling times. The non-magnetic forcer coil
provides high force with zero cogging for smooth velocity and position control,
and is ideal for applications requiring outstanding contour accuracy and smooth
velocity profiling. The linear motor has zero backlash, no windup, zero
friction, and outstanding system responsiveness, and the magnetic field 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.
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 maximum flexibility.
Optional 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.
ACT actuators consist of noncontact linear motors and
encoders, making them virtually maintenance-free. As a result, there is no
maintenance that is normally associated with contacting-type systems such as
ball screws or belt drives.
The flexible design is offered with multiple cable
management and limit options to suit your needs. 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 applications.
