Ultra-Smooth, Precise Motion
Aerotech’s high-power, cog-free linear motors drive the PRO LM series. The non-magnetic forcer coil provides high force with zero cogging for ultra-smooth velocity and position control. This zero-cogging design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling. Aerotech’s linear motor stages have zero backlash, no windup, and outstanding system responsiveness. The magnetic field of the linear motor is totally self-contained within the U-channel design, making these stages well-suited for high-performance applications that cannot tolerate the stray magnetic fields generated by flat motor magnet tracks.

Noncontact linear encoders with micron-level repeatabilities are standard on all PRO LM series stages. Either a line-driver output or amplified sine-wave output encoder is available. The optional HALAR factory calibration further increases the standard accuracy and repeatability.

Construction Features
Sealed linear motion guide bearings with integral wipers are incorporated to provide excellent payload capacity and long life. Both the metal waycover and tabletop are treated with a hardcoat that is scratch-resistant and provides outstanding protection in the harshest applications, while the tabletop utilizes stainless steel Helicoil™ inserts to protect mounting holes against thread wear. Several tabletop options are available for metric or English mounting, as well as for direct interface with our popular ADRS, ADRT, and AGR rotary stages. In addition, configurable cable management options are available for single- or multi-axis systems.
