Product Description:

The MLS300S-3A-0600-HNNN is a secondary section from the MLS Synchronous Linear Motors series produced by Bosch Rexroth Indramat. As a moving platen that rides over a fixed primary track, this component generates thrust for straight-line positioning tasks in automated assembly cells, gantries, and transfer lines. It is identified by the manufacturer as a secondary motor part and forms the force-generating element of an iron-core linear servo system used where direct, backlash-free motion is required.

The secondary plate is built on a steel base that provides the stiffness needed for accurate air-gap control and effective heat conduction to the machine frame. Its magnet rail is populated with permanent magnets that interact with the primary coil’s field to create propulsion without mechanical gears. The enclosure has an IP65 protection rating, so dust and low-pressure water jets will not affect service life. Mechanical attachment uses screw fastening, and an integrated M10 transport thread simplifies safe handling during installation or removal. The segment is 0600 mm long, providing a 0.6 m active magnet array. The part has a depth of 345 mm, which must be considered when allocating installation space behind the guideway.

The magnetic circuit is intentionally unshielded, allowing flux to couple efficiently with the primary while requiring adequate spacing from ferromagnetic machine parts. To protect the magnet blocks from chips or coolant splashes, the unit is supplied with a cover sheet that spans the full length of the 300-frame body. The frame code 300 matches the motor with complementary primary coils of the appropriate width, and the design is classified as secondary motor type S for standard force density. The total moving mass is 42.0 kg, which must be considered when sizing bearings and setting acceleration profiles.
