Linear Motors with magnet-free secondary section track

Many applications in the machine tools and production machines require long traversing distances to be traveled rapidly and precisely. The high cost of permanent magnets has meant that linear motors are expensive for these very long axes. CNC Design offers with the new 1FN6 linear motor a synchronous linear motor developed by Siemens with a magnet-free secondary section track. The motor has all the qualities of a synchronous direct drive such as high precision, outstanding dynamic response, the absence of a need for maintenance, a high force density and low energy losses. At the same time, the fact that no permanent magnets are used means is it easy to install, inexpensive and very robust.

Typical 1FN6 applications in machine tools are water-jet or laser-beam cutting machines. However where they really start to shine is in very long traversing axes for handling and linking applications. The robust and modular design makes 1FN6 suitable for many applications. Any number of secondary sections can be mounted next to each other and several primary sections can be operated on a secondary section track.
