Feature | Ironcore Motors - LMSA series

The three-phase motor iron core is comprised of a primary side (forer) and secondary side (stator) permanents. The stator can be infinitely extended, so the stroke will be unrestricted.

  • High force density
  • High dynamic response
  • Lower installation height
  • Continuous force from 103N to 1579N
  • Peak force from 289N to 4458N
  • Assembly total height 34mm, 36mm
