Product Description:

The MLS300S-3A-0600-RNNN secondary section is produced by Bosch Rexroth Indramat for the MLS Synchronous Linear Motors series. It serves as the stationary magnetic track that works with a moving primary carriage to generate direct thrust, allowing gantries, machining centers, and material-handling axes to convert electrical drive signals into precise linear motion without belts or screw drives. By supplying the reaction surface for synchronous forces, the part fits industrial automation layouts that demand high acceleration, repeatability, and minimal maintenance.

This segment has an IP65 protection rating, so dust and low-pressure water jets cannot reach the internal magnet set. Each magnet pole spans 37.5 mm, establishing the electrical wavelength used by the drive for commutation and position feedback. A segment length of 0600 mm provides 600 mm of active travel per piece, and multiple sections can be joined for longer strokes. Installation uses mounting holes for M6 fasteners that are machined through the carrier. These holes accept bolts manufactured according to the DIN EN ISO 4762 standard. When grade 8.8 screws are used, the specified tightening torque is 10 Nm, providing secure clamping to steel or aluminum machine frames without deforming the lamination stack.

The secondary assembly can operate at temperatures up to 70 °C, helping prevent excessive thermal expansion or magnet demagnetization under typical plant conditions. Mechanical protection is enhanced by a factory-fitted stainless-steel cover sheet that guards the magnet faces against chips and coolant splashes. Size code 300 identifies the wider motor platform within the MLS family, matching this track to primary modules that share its force rating and stator width. Because it is a secondary part, the assembly contains no windings or sensors, which simplifies field wiring and reduces the moving mass of the axis.
