Aerotech's Linear Motor Stages

Aerotech'sPRO LMseries of high-performance linear motor stages are offered in four differentseries with 38different modelsin travels from100 mm to 1.5 m. The PRO165LM,PRO225LM, PRO280LM and PRO560LM allfeature a linear motion guide bearing system and high-performance brushless linearservomotor.

Aerotech'shigh-power, cog-free linearmotors drive the PRO LMseries. The non-magnetic forcer coil provides high force with zero cogging forultra-smoothvelocity andposition control. Aerotech's linear motor stages have zero backlash and nowindup. The magnetic field of the linear motor is self-contained within theU-channel design, making these stages well-suited for high-performanceapplications thatcannot toleratethe stray magnetic fields generated by flat motor magnet tracks.

Noncontact linear encoders with micron-level repeatabilities are standard onall PRO LMseries stages. Either a line-driver output or amplified sine-wave outputencoder is available. The optional HALAR factory calibration further increasesthe standard accuracy and repeatability.

Sealed linear motionguide bearings with integral wipers are incorporated to provide payloadcapacity and long life. Both the metal waycover and tabletop are treated with ahardcoat that is scratch-resistant and provides protection in the harshestapplications, while the tabletop utilizes stainless-steel Helicoila" cent inserts toprotect mounting holes against thread wear. Several tabletop options areavailable for metric or English mounting, as well as for direct interface withour popular ADRS, ADRT, and AGR rotary stages. In addition, configurable cablemanagement options are available for single- or multi-axis systems.
