Configure Size

The LMXK is HIWIN USA's quick-delivery linear motor stage: a high-force synchronous ironcore motor riding Q-series SynchMotion guideways on an anodized aluminum base, built in the USA from Taiwanese and other parts. Three motor sizes in standard or low back-EMF windings span 103 to 308 N continuous with strokes to 3,700 mm and velocities to 5 m/s, and single axes combine into cross tables, cantilevers and gantries.

Need micron-class accuracy or cleanroom sealing instead of quick-delivery force? LMSSA is the precision-stage sibling with ±1 µm repeatability and an ISO class 2 cover. View LMSSA Series →

5 m/s
