Product Description:

The MCS015-3S-0099-NNNN is a secondary element in the MCS Linear Motors series produced by Bosch Rexroth Indramat. As an ironless linear motor secondary part, it supplies the magnet track that reacts with the primary coil to generate thrust in high-precision positioning stages. Within an automation axis, its role is to provide a light magnet track that supports smooth, direct linear motion while fitting the dimensional conventions of the 015 frame. This arrangement suits direct-drive applications where low cogging and accurate linear travel are important to overall axis performance.

The secondary part stands 51 mm high and 14.8 mm wide, matching compatible carriages and helping keep the air gap uniform. Protection is classified as IP00, so it must be mounted inside a closed machine envelope where the surrounding assembly provides shielding from contact. Relative linear mass is 3.0 kg/m, allowing moving-system inertia to be estimated during axis design and helping the magnet track remain suitable for compact layouts. Through-holes of 4.5 mm diameter accommodate a screw-based fastening arrangement, and a corrosion-protective coating on the magnets helps prevent oxidation without adding noticeable thickness. The narrow profile also helps the part fit closely with the primary section in linear modules where available space is limited.

Each delivered segment is 99 mm long and weighs 0.3 kg, which helps keep short rail sections compact and limits added moving mass. The tapped holes use an M4 thread, and the specified tightening torque is 3.1 Nm to clamp the strip without distorting the ironless structure. The short segment length also supports modular rail layouts in which multiple sections are placed in sequence to match the required stroke length. Because these tapped holes are the clamping points, the secondary part can be mounted in a controlled position while preserving the uniform magnet field needed for smooth thrust generation. The passive magnet track supports direct linear motion without adding cabling or active electrical components to the secondary section.
