Product Description:

The Bosch Rexroth Indramat MLS300S-3A-0450-NNNN is a secondary segment in the MLS Synchronous Linear Motors series. Paired with a moving primary coil, it supports direct linear thrust without gearboxes for gantries, pick-and-place heads, and conveyor shuttles. A steel carrier with permanent magnets and a repeatable mounting pattern allows machine builders to extend the available travel by adding identical segments. This modular arrangement supports long linear paths without requiring a single continuous magnetic track.

The segment uses the MLS mechanical interface with a motor size of 300, giving it a nominal width of 300 mm that matches compatible primary frames. Its active section has a length code of 0450, indicating that the magnetic track extends 450 mm for each installed segment. Mounting relies on metric fasteners, and the through holes accept M8 screws. Each screw requires a tightening torque of 37 Nm to provide even clamping without distorting the magnet array. The screws must have a strength grade of 10.9 to withstand the attraction forces between the magnets and the iron secondary while resisting vibration during high-speed strokes. The segment is secured with screws, eliminating the need for adhesive or dovetail guides.

The segment has an unshielded magnetic design, so nearby ferromagnetic parts must be positioned with enough clearance to avoid unintended attraction. All mounting holes are located along the outer edge, keeping the central magnet surface clear for uninterrupted force production. A fitted cover sheet provides a protective stainless steel layer over the magnets and helps guard them against chips or coolant splashes. Each segment also includes M10 transport threads, allowing lifting eyes to be attached without placing stress on the functional mounting holes. The secondary motor type is coded as S, identifying the segment as the passive magnetic track that interfaces with the energized primary. Its accessible edge-mounted fasteners allow the segment to be installed or removed without disturbing the central magnetic surface.
