Product Description:

The MLS070S-3A-0450-NN02 is a secondary section from the MLS Synchronous Linear Motors series produced by Bosch Rexroth Indramat. In a linear drive, the secondary part carries the permanent magnets that react with the primary coil set. This arrangement converts electromagnetic attraction into direct thrust for gantries, cutting tables, or transfer lines without using rotary-to-linear mechanics.

The carrier rail is machined from C45 carbon steel, giving the magnet track the stiffness needed to keep gap variations low. A base plate made of steel and a cover sheet of Stainless Steel V4A shield the magnets from impact and fluids while maintaining ferromagnetic continuity. Motion is generated by a row of Permanent Magnets bonded along the rail, and their alternating polarity follows the pole pitch so motor force remains sinusoidal. Mechanical integration is straightforward because the rail supports mounting with screws into a machine bed, and each mounting hole repeats on a 75 mm pitch that aligns with standard T-slot frames. The motor size code 070 corresponds to the 105 mm frame width, and type S marks this as a single-row secondary suited to MLS primaries that supply three-phase currents.

Performance is tied to geometric spacing. A pole pitch of 37.5 mm matches the electronic commutation sequence, while the rail’s 105 mm overall width sets the working air gap for the magnetic flux path. A mass of 4.2 kg for this segment keeps the moving load moderate when the rail is mounted to a carriage instead of a fixed bed. The segment length of 450 mm allows smooth force production across that travel distance without cogging. An end-hole offset identical to the pole pitch simplifies stacking of multiple segments so larger strokes can be created without altering the mounting datum.
