Product Description:

The MLS140S-3A-0150-NNNN belongs to the MLS Synchronous Linear Motors series produced by Bosch Rexroth Indramat. It is supplied as a secondary part that integrates into a linear motor track and interacts with the primary coil to generate thrust along a straight path. In industrial automation, this component forms the passive magnetic element of gantries, pick-and-place modules, or shuttle axes where contact-free motion, low wear, and exact positioning are required.

The secondary rail is built on a steel base plate, giving the segment the stiffness needed to resist bending when clamped to machine frames. A segment length of 150 mm allows multiple modules to be combined to match the required stroke without cutting or re-machining the part. Its motor size code of 140 indicates a 140 mm wide magnetic footprint that pairs with a matching primary unit. System mass calculations must include the relative mass of 18.8 kg/m; this value is useful for sizing support structures and drives. Mechanical attachment uses screw mounting, so the rail can be fastened directly to a steel or aluminum backbone without adhesive bonding or special clamps.

The component is a secondary part, so it contains no windings and adds no electrical heat to the axis. It uses permanent magnets to supply a constant magnetic field, which eliminates the need for external excitation and keeps power consumption on the moving carriage low. Mechanical protection is provided by a cover sheet that shields the magnet faces from chips and accidental contact during installation. Handling weight for a single segment is 2.8 kg, which keeps each section manageable during assembly. Orientation is simplified by the south-pole marking “S,” and the secondary motor type “S” indicates the standard pole arrangement used throughout the series.
