    Iron-Core Linear Motor
    The LMSA Series is HIWIN’s three-phase iron-core synchronous linear motor.
    The LMSA Series is comprised of a primary side (forcer) and secondary side (stator) permanent magnets. The stator can be infinitely extended, so the stroke will be unrestricted.

  • High dynamic response
  • Low installation height
  • UL and CE certification
  • Continuous force range from 103N to 1579N
  • Peak force range from 289N to 4458N
