Product Description:

The MLS200S-3A-0150-NNNN secondary segment is produced by Bosch Rexroth Indramat for the MLS Synchronous Linear Motors series. This component is installed along the machine bed to provide the ferromagnetic track that a moving primary coil rides against. When energized by the matching drive, the complete linear motor replaces rotary motors and ball screws, delivering direct, low-maintenance thrust for positioning, feeding, or gantry axes in industrial automation cells. The segment incorporates a pole marking of S that simplifies installation orientation and ensures the magnetic sequence continues without phase error across multiple sections.

Each secondary segment follows a defined mechanical envelope so it mates precisely with adjacent pieces. The motor size of 200 establishes the active width and height, matching primary units of the same frame class. A segment length of 0150 millimeters helps build incremental strokes while limiting individual weight. The linear mass density is rated at 26.9 kg/m, a value used to calculate support requirements for long tracks. The individual secondary weighs 4.0 kg, which permits manual placement during installation. The segment has a protection class of IP65, so the laminated core tolerates airborne dust and water jets in machining cells. Attachment uses M6 fixing screws, allowing consistent clamping force without special hardware.

The mounting arrangement relies on countersunk hex screws that conform to DIN 7984. When grade 8.8 fasteners are used, the recommended tightening torque is 10 Nm. The segment comes with a cover sheet, which shields the magnetic surface from chips and helps prevent accidental contact during maintenance. Adjacent sections maintain the magnetic sequence across butt joints without additional adhesive retention between segments after fastening.
