Product Description:

The MLS140S-3A-0600-NNNN is a secondary component from Bosch Rexroth Indramat’s MLS Synchronous Linear Motors series. Installed as the stationary track in a linear drive, it provides the magnetic circuit required for contact-free thrust when paired with the active primary mover. The segment supports high-precision positioning in assembly cells, pallet shuttles, and gantry modules where smooth, maintenance-free motion is preferred over traditional screw or belt mechanisms. Its modular form allows multiple secondary sections to be arranged along an extended travel path while the primary mover produces controlled linear motion.

This segment is sealed to IP65, so dust and low-pressure water jets cannot enter the lamination stack or magnet assembly. Its linear mass is 18.8 kg/m, a value used to size support rails and calculate structural loads during machine operation. The segment is secured with screws, and its clearance holes accept M6 bolts that clamp the back iron directly to the machine base. The magnetic poles repeat every 37.5 mm, providing consistent magnetic spacing for precise position and thrust control. Length code 0600 represents a 600 mm active section, enabling modular extension of the travel path without changing the basic motor arrangement. A stainless steel cover sheet shields the magnets from chips and cleaning fluids while preserving the required air gap between the primary and secondary components.

The motor size index of 140 corresponds to the electromagnetic cross section used in higher-thrust MLS assemblies. This secondary component weighs 11.3 kg, which must be considered during handling and when the segment is integrated into a vertical axis. Continuous operation is permitted up to a secondary temperature of 70 °C, and the drive should limit current if the temperature approaches this maximum. The segment has an overall width of 175 mm, aligning it with the standardized carriage geometry associated with the S-type secondary classification. Adequate support beneath the back iron helps maintain a uniform air gap across the active travel length. The mounting surface should remain flat and free of debris so the cover sheet and magnetic track are not distorted during installation.
