Product Description:

The MLP140B-0120-FS-N0CN-NNNN is a primary section in the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. As a synchronous linear motor module, it converts drive current directly into thrust along a flat track, removing mechanical transmissions in gantry stages, pick-and-place systems, and processing stations. The unit serves as the active force-generating element, and when paired with a passive secondary rail it delivers precise straight-line motion for tightly synchronized industrial automation sequences. This direct-drive arrangement reduces backlash and compliance that can appear in belt- or screw-based axes, helping the motion system respond quickly to changing commands.

Thermal management relies on liquid cooling, where coolant channels inside the iron core remove heat so continuous force can be maintained without derating. Power conductors use front cable routing, allowing cables to run parallel to the motion axis and shortening service loops. Component integrity is maintained by a standard encapsulation method that seals the winding pack against coolant ingress and vibration. Position feedback hardware is absent, and the part ships with no encoder installed, so external sensors or drive-side software commutation must be chosen. The active section belongs to motor length B, giving medium stroke coverage within the 140 mm wide family.

Application layout is completed by selecting a carriage that matches motor size 140, which fixes the 140 mm stator width and the corresponding secondary track geometry. Integration with a compatible drive lets the module operate under field-oriented control, and compatibility across the MLP Synchronous Linear Motors platform permits mixed length combinations on one axis. This allows different primary lengths to be used within the same motor platform while keeping the same basic operating principle. Liquid transfer fittings, mounting holes, and the dedicated liquid cooling circuit remain identical across B-length units. The front-fed cabling channel stays clear of moving carriers, so thermal hoses and signal lines remain stationary even during peak acceleration moves.
