Santa Clarita, CA —-- H2W Technologies' single rail positioning stage (SRS-020-08-013-01-3EX) utilized in a six axis demo, which coordinates the motion of three linear motor driven axis with three rotary motor driven axis. It utilizes AMC's Click&Move® automation solution software along with AMC's servo drives to achieve the desired motion profiles. There is no external controller or hardware used..

The multi-axis SRS-EX series stage is ideal for closed loop positioning applications that require independent multiple motions on a single travel plane in a compact, small footprint. Each moving table has an independent encoder head reading a single encoder scale. This allows for each moving table to be easily tracked by any multi-axis motion controller. It is assembled on a single piece of aluminum extrusion allowing for long travel distances without the need of machining additional components. The ironless core coil assemblies have no magnetic attractive force to the stationary magnet assembly, which results in zero cogging and increased life of the bearing system. Choosing to move the motor coils reduces the moving mass of the system allowing for much higher accelerations of light payloads.


  • Single extrusion lengths up 6 meters long allowing for long strokes
  • Ability to run multiple motors coils on single magnet track under closed loop control
  • Custom strokes, forces, feedback resolution, and vacuum compatible configurations available
