Product Description:

The MCS040-3S-0120-NNNN is an ironless linear motor secondary part manufactured by Bosch Rexroth Indramat for the MCS Linear Motors series. When paired with the corresponding primary section, it supplies the magnetic track required for direct-drive positioning stages and gantry axes used in industrial automation cells and transfer systems. The passive design carries no windings, so all forces are induced by the traveling primary carriage, which reduces heat in the work zone and simplifies thermal management inside compact machine spaces.

The component is secured with screws that pass through a clearance drill of 6.4 mm, which sets the maximum shank size that can be used without enlarging the base plate. Machine frames must provide a matching M6 thread, and the allowable screw-in depth is limited to 11 mm to avoid distorting the laminations. The motor has a height of 86.4 mm and a width of 34.3 mm, so nearby sensors, guards, or cable trays must be placed with enough clearance for the full assembly. Frame size 040 with a secondary part length of 120 mm and a tightening torque of 10.4 Nm establishes the mounting layout, and the standard mounting style lets the unit fit into pre-machined recesses without shims or spacers during installation and alignment.

The steel base plate has a U-Shaped form that resists bending under attraction forces and helps maintain pole alignment along the guideway. A pole width of 30.00 mm matches the magnet pitch of the companion primary mover for even flux distribution across the travel stroke. The enclosure rating is IP00, so the unit requires installation inside a sealed housing to prevent accidental contact or debris exposure. Its mass of 1.3 kg keeps added load low on overhead or moving-frame assemblies while still providing a rigid magnetic track during high-thrust motion.
