Product Description:
The MLS202S-3A-0540-NNNN is a secondary section for a synchronous linear motor track manufactured by Bosch Rexroth Indramat within the MLS Synchronous Linear Motors series. Designed for long-stroke positioning stages, it works with primary coils to transform electromagnetic force directly into linear motion, eliminating the need for gearboxes and ball screws. In automated assembly lines, pick-and-place gantries, and pallet transfer systems, this segment extends the available travel while supporting the precision and speed expected from iron-core linear drives. Its passive design also avoids the mechanical wear associated with conventional rotary transmission components.
Its active length is 540 mm, so each section adds slightly more than half a meter of travel when multiple sections are arranged sequentially. The unit weighs 17.4 kg, which must be considered when sizing gantry beams or machine frames that carry several sections. A carrier made of steel provides structural rigidity and forms a magnetic return path for the linear motor. Linear thrust is produced through embedded permanent magnets, which provide a constant magnetic field that interacts with the energized primary. The element is a secondary motor type S, making it compatible with the corresponding MLS primary sections intended for medium force density. Because the secondary sections can be placed in sequence, the track can accommodate applications requiring travel beyond the length of a single segment.
The segment has threaded mounting holes on the outer edge, allowing it to be secured from above without disturbing neighboring track sections. The unit is secured with screws, so installation does not require adhesive bonding or press-fit tooling. This fastening method also permits controlled positioning while the sections are aligned along the machine frame. During assembly, adjacent sections must remain evenly aligned so the primary can move across the track without abrupt changes in the operating air gap. The magnetic array is protected by a cover sheet, which helps prevent chips and coolant from reaching the permanent magnets in machining environments. The cover also provides a smooth exposed surface that reduces direct contact with the magnetic components during handling and installation.
