Product Description:

The MLS040S-3A-0450-NNNN is a secondary section from the MLS Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. This steel-based linear motor segment mounts to the machine bed and interacts with a primary coil to generate thrust along a straight path, eliminating rotary-to-linear conversions in automated handling, gantry, or machining systems. As a passive secondary part, it provides the magnetic track and mechanical reference needed for contact-free propulsion while keeping moving mass low for rapid acceleration.

The segment is assigned Motor Size 040, which indicates a 40 mm pole pitch that matches MLS primary components of the same size class. Its active length is listed as Segment Length 0450, so 450 mm of magnetic surface is available for force production and overlapping mover travel. Its dimensions include a Width 450 mm across the magnet face and a Depth 75 mm from the cover sheet to the mounting surface, allowing close placement inside compact machine frames. The Secondary Part Mass 2.4 kg helps limit the inertial load added to the axis, which supports agile servo dynamics on high-speed shuttle axes.

A sealed housing provides an IP65 protection rating, so airborne dust and low-pressure water jets do not reach the magnet stack or fastening hardware. The backing plate is made of Steel for mechanical stiffness and thermal conduction, and the element is secured through elongated holes with metric M6 screws that meet the DIN 7984 low-profile head standard. Operation is permitted up to a part temperature of 70 °C; above this limit, magnetic flux can weaken. Permanent magnets supply the excitation field, and a cover sheet adds mechanical protection against chip impact. The unit uses S secondary motor type geometry and is fixed directly with screws rather than clamping rails.
