Ordering data

The simple mechanical construction without transmission elements, such as ballscrew, coupling, or belt, enhances the reliability of the drive components.

Heat loss occurs almost exclusively in the primary section and is dissipated via an integrated liquid cooling system. The Thermo‑Sandwich dual‑circuit cooling system permits both a thermal decoupling of the motor from the machine, and also a low‑priced cooling design.

The stainless metal encapsulation of the primary section ensures the high mechanical ruggedness and resistance to soiling required for use in machine tools and production machines, as well as high resistance to corrosive liquids. In addition, the motor places minimal demands on the preparation of mounting surfaces thanks to the large air gap. The mounting tolerances for the air gap are ± 0.3 mm (0.01 in).

Design variants

SIMOTICS L-1FN3 linear motors are available as single‑sided or double‑sided motors.

• Single‑sided motors
  The single‑sided version consists of a primary section that is arranged in parallel to the associated secondary section.
• Double‑sided motors
  The special secondary section of the double‑sided version is positioned between two primary sections (one primary section with standard winding and one with complementary winding). The design as a double‑sided motor is particularly suitable for applications with movable secondary section and small traversing paths with fast acceleration (e.g. non‑circular machining).
