Product Description:

The MLS200S-3A-0450-NNNN secondary section is produced by Bosch Rexroth Indramat within the MLS Synchronous Linear Motors series. It functions as the secondary mover in a linear motor assembly. This steel-backed carriage travels over a powered primary track to supply direct thrust for machine modules that require precise point-to-point positioning. By eliminating rotary gearboxes, belts, and ball screws, the component provides smooth motion for packaging lines, assembly platforms, and gantry systems in industrial automation. The reduced number of mechanical transmission components also limits wear and routine maintenance requirements.

The housing follows the motor size 200 frame code, providing a magnetic surface suitable for mid-range force requirements. Its track uses a pole pitch of 37.5 mm, allowing the drive controller to calculate commutation with a constant electrical wavelength. A section length of 0450 positions twelve poles under the carriage and provides a stroke suitable for modular machine layouts. The moving mass is 12.1 kg, allowing high acceleration without excessive current demand. The enclosure meets IP65, protecting the permanent magnets and internal interfaces against dust and sprayed liquids. This protection supports operation near machining processes, packaging equipment, and other systems where airborne particles or occasional coolant exposure may occur.

The steel base plate is drilled along its outer edge and accepts M6 DIN 7984 flat-head screws. This arrangement matches the screw-fastened design, while a cover sheet protects the mounting area. The secondary type S carrier has a width of 450 mm and a depth of 235 mm, allowing it to fit standard cradle brackets while leaving clearance for adjacent machine components. When grade 10.9 fasteners are used, the joints support a tightening torque of up to 15 Nm. Grade 8.8 screws permit a tightening torque of up to 10 Nm. Embedded permanent magnets maintain consistent magnetic flux along the pole line, supporting smooth continuous force as the carriage moves across the primary track.
