Product Description:
The MLS040S-3A-0150-NNNN is a secondary section from the MLS Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. It serves as the permanent-magnet track in an open kit motor and interacts with the primary coil set to generate controlled linear thrust. This arrangement supports precise movement in positioning tables, gantry axes, pick-and-place modules, and other automated machinery. Because the secondary section contains no energized windings, the compatible primary and drive controller regulate thrust, speed, and position during operation.
The segment uses an open motor design, but a cover sheet protects the magnetic surface from chips and other mechanical contact. The assembly has a protection class of IP65, providing resistance to dust and water jets when it is installed correctly. Its segment length is 150 mm, and its segment width is 75 mm. The fixing pattern has a 60 mm hole-center width, a 75 mm hole pitch, and a 37.5 mm end-hole offset, allowing the rail to align with suitable mounting surfaces. Screws pass through holes with a diameter of 7 mm, while the corresponding counterbores for the screw heads measure 11 mm. A North/South pole arrangement extends along the travel axis, and the S-pole marking helps establish the correct magnetic orientation during assembly. The component belongs to secondary motor type S and is secured directly to the machine structure through its prepared mounting pattern.
The secondary section has a linear density of 5.4 kg/m, which limits the added load on the supporting machine structure. Each individual segment weighs approximately 0.8 kg, making it suitable for modular track layouts that use multiple sections in sequence. Continuous operation is permitted while the secondary temperature remains at or below 70 °C; operation above this limit requires reduced loading. The motor size code is 040, allowing the secondary section to pair with an MLS primary of the corresponding size. Multiple sections can be positioned end to end to provide the required travel distance while maintaining a consistent magnetic path. Proper alignment of adjacent sections helps the primary move smoothly across segment transitions without disrupting the commanded linear motion.
