Product Description:

The MLS140S-3A-0150-NNNN/S002 secondary part belongs to the MLS Synchronous Linear Motors series from Bosch Rexroth Indramat. Designed for direct-drive applications, this component forms the moving element of a linear motor system and generates thrust along a track without using gearboxes or ball screws. In industrial automation, it works with a matching primary coil assembly so machines can achieve accurate linear motion with fewer mechanical transmission parts. This arrangement supports fast positioning, smooth travel, and reduced wear in systems that depend on repeated back-and-forth movement.

The unit uses a screw-mounted design, and the recommended fastener size is M6, applied through holes that are predrilled in the laminated core. For high-strength bolts of property class 10.9, the tightening torque is 15 Nm, while class 8.8 hardware should be tightened to 10 Nm so the clamping load stays within the intended range. An integrated cover sheet helps protect the assembly from chips, and the mounted unit has an IP65 rating to resist dust and low-pressure water exposure. Because the secondary element is supplied as an Open (Kit Motor) package, the mounting structure must provide the required ferromagnetic support surface and allow clear airflow around the exposed stacks.

The motor size is 140, which corresponds to the nominal width of the steel lamination used for this secondary part. This version uses the S secondary type and segment length code 0150 for applications that need a compact moving element within a linear axis. Its dimensions are 175 mm in height and 150 mm in active length, which helps it fit into machine frames where installation space is limited. Despite the solid steel construction, the assembly weighs only 2.8 kg, which helps keep moving mass lower during rapid acceleration and frequent position changes.
