- The HIWIN permanent magnet synchronous linear motor LMFA has a built-in
water cooling system, with a special electromagnetic and thermal design.This
motor has a high thrust density, and a max peak force of 20,000 N.
The three-phase motor is comprised of an iron core primary side (forcer) and a
permanent magnet secondary side (stator).
- Water-cooled design
- Ultrahigh thrust density
- UL and CE certification
- Continuous force range from 74N to 7917N
- Peak force range from 282N to 20,827N
The stator can be infinitely extended, so the stroke will be unrestricted. The LMFA series is widely used in the machine tool industry, laser processing machines, glass cutting machines and active vibration suppression platforms.
