Hiwin Ironcore Motors – LMFA series

Feature | Ironcore Motors – LMFA series

This motor has a high thrust density, and the maximum Peak force is up to 20,000N. The three-phase motor is comprised of an iron core primary side (forcer) and a permanent magnet secondary side (stator). The forcer can use multiple units and can be infitely extended, so motor moving stroke is not restricted. The LMFA series is widely used in the machine tool industry, laser processing machines, glass cutting machines and active vibrative suppression platforms.

  • Water-cooled design
  • Ultrahigh thrust density
  • UL and CE certification
  • Water-cooled continuous force range from 149N to 7,917N
  • Peak force range from 282N to 20,827N
  • Installation height 48.5, 50.5, 64.1, 66.1 (mm)
