SIMOTICS L-1FN3 Linear motors

SIMOTICS L-1FN3 motors are linear drives in compact design featuring superior performance / force density. They are characterized by wear-free force transmission. SIMOTICS L-1FN3 motors fulfill the highest requirements placed on dynamics, contour accuracy and precision and are optimized for operating high-performance machine tools and production machines. Water-cooled SIMOTICS L-1FN3 motors are available in two versions: for peak load and continous load.

SIMOTICS L-1FN3 – the modular industry standard

The water-cooled SIMOTICS L-1FN3 was specially developed for use in machine tools and has been the proven standard for linear motion for years. Its modular principle offers you a comprehensive range of practically wear-free and therefore low-maintenance motor variants in seven different widths with up to five different lengths and several types of action.


The motors are designed for operation with SINAMICS S120 converters.


The water-cooled SIMOTICS L-1FN3 motors are available in two versions – for peak load operation and continuous load operation.

SIMOTICS 1FN3 Benefits

With a linear motor, every movement sits perfectly

Whether accuracy, precision or economy of applications with linear motion – you are always right with the SIMOTICS L-1FN3.

The benchmark for directly driving linear axes

The main advantage of linear direct drive technology is the extensive avoidance of the effects of elasticity, play, and friction, as well as natural oscillation in the drive train. This results in a higher dynamic response and increased precision. 



  • Highest precision linear motion with high dynamic performance
  • Enormous force density in a compact design
  • Highest traversing velocities for all applications
  • Large air gap, therefore extremely rugged against external influences
  • Wide range of options depending on the application profile
  • Wear-free drive components 
  • Low lifecycle costs of machines 
  • Milling, turning and grinding machines
  • Laser machining centers 
  • Handling systems 
  • Oscillators
  • Test setups
