Moving Lamination linear servo motor (SL)

MOTX linear motors with a continuous force of up to 800 N enable accurate and highly dynamic positioning.

The SL series linear servo motors offer precise linear positioning at very high speeds. These linear motors are connected directly to the mechanics that needs to be moved. This direct connection enables an excellent servo responsiveness that leads to a faster settling time for any motion.

The SL series feature an iron core design that effects a high force density while at the same time offering very low cogging. As such these motors are perfectly suited for applications that require smooth motion such as scanning or printing.

The SL linear motor can replace ball-screws, rack and pinion, belts, core-less and iron core linear motors.

For the same cross section shape, various length, rated force and maximum speed can be fit to specific needs by windings length, winding wire section and carriage length.


  • Stroke lengths of 20mm to 2,000MM .
  • Peak force of up to 1,500N
  • Continuous force of up to 800N.


  • Cableless.
  • Eliminate transmission components that wear, such as gears, screws and belts.
  • Direct connection to the moving load.
  • Very high speed and acceleration.


  • Lower cost than comparable iron-core linear motors.
  • Cable-less – no moving cables.
  • Light carriage – high acceleration.
  • Heat-free carriage – no heat dissipation.
  • No attraction force


  • This configuration is an attractive high performance replacement of ball screws and iron core linear motors.
