Design Features

The ACT140DL 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 ACT140DL 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 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, simple connectorized pigtails are available. Moveable limits allow easy adjustment of usable travel for varying application requirements.

  1. Bi-directional repeatability specification listed requires resolution of 0.1 µm or finer. Specification is ±2 µm with resolution of 0.5 µm. Coarser resolutions will result in reduced bidirectional repeatability performance.

  2. Maximum velocity and acceleration specifications assume a small payload. As payload increases, the maximum attainable velocity and acceleration will decrease. Maximum application velocity may be limited by system data rate and resolution.

  3. Requires -AC1 air cooling option.

  4. Axis orientation for on-axis loading is listed.

  5. Specifications are for single-axis systems measured 25 mm above the tabletop. Consult factory for non-standard applications.
