Product Description:

The MLS070S-3A-0150-NNNN is a secondary segment from the MLS Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. Designed for direct-drive positioning systems, this component provides the stationary magnetic track that interacts with a moving forcer to generate thrust without conversion gears or screws. By forming a flat, rigid path along the machine axis, it supports accurate, high-speed motion in pick-and-place cells, packaging lines, and light machining centers where repeatable linear travel is required. Because force is produced without recirculating mechanical transmission elements, the axis can avoid backlash that is common in screw-driven arrangements.

The segment has a mounted depth of 105 mm, allowing installation under compact carriages while leaving space for cable carriers. Its enclosure carries an IP65 rating, preventing dust or coolant spray from contacting the internal magnet array. That array uses permanent magnets, creating a constant flux field so the driven coil can develop force with no mechanical wear at the secondary. Continuous operation is permitted up to a 70 °C component temperature, enabling duty cycles aligned with typical machine cooling capacity. The frame conforms to size code 070, giving standardized width and mounting hole spacing across the MLS range. Screw mounting holds the secondary firmly against the base structure, which helps maintain the air gap needed for consistent thrust production.

The magnetic circuit is bonded to a base plate of steel, supplying stiffness that resists bending under attraction forces between the primary and secondary elements. With a secondary part mass of 1.4 kg, the added inertial load on the axis remains low and supports aggressive acceleration profiles. Ordered length code 0150 indicates a 150 mm segment, and multiple units can be tiled to match long strokes. Mechanical protection is provided with a cover sheet, which shields the magnet faces from chips during operation. The secondary motor type is S, indicating the standard pole pattern used across MLS drives.
