Product Description:
The MLS202S-3A-0180-NNNN secondary track is supplied by Bosch Rexroth Indramat as part of the MLS Synchronous Linear Motors series. It interacts with the primary mover to generate thrust along a guided axis, allowing gantry stages, pick-and-place heads, or transfer shuttles to move without ball screws or belts. The magnetic steel laminations and reaction surface form the linear path along which the powered primary coils travel in automated assembly and packaging lines. This arrangement eliminates several mechanical transmission components that would otherwise introduce backlash, wear, and additional maintenance requirements.
The track is fixed with screws, so each segment is clamped directly to the machine frame through pre-drilled holes. This mounting method establishes an accurate datum and resists movement under acceleration. A factory-installed cover sheet shields the laminations from chips, fluids, and stray ferrous fragments, reducing debris accumulation around the moving primary. The linear density is 32.3 kg/m, which helps determine the required rail support spacing along the machine frame. Each module weighs 5.8 kg, making its mass an important consideration when planning supports and handling the segment during installation. Adjacent modules must remain aligned so the primary can travel smoothly across the joints without interference.
The item is categorized as the secondary part of a linear motor and carries the steel lamination stack, while the energized coils remain in the primary slider. The S designation indicates the standard polarity pattern used by the series, ensuring magnetic pitch compatibility between adjoining track segments. Interconnected sections form a continuous reaction rail, and the track can be cut to the required application length without changing the electrical characteristics of the primary. Because the secondary track contains no energized windings, most operating heat remains in the moving element. The fixed rail is therefore less affected by duty-cycle heating than the powered primary, although the mounting surface must still maintain proper alignment during operation.
