Product Description:

The MLP100B-0250-FS-N0CN-NNNN primary section is produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. Acting as the moving coil, it slides over a permanent-magnet track to generate thrust directly along the axis, removing belts, screws, or gearboxes from the drive train. This direct-drive arrangement suits high-speed pick-and-place gantries, portal axes, and machining modules where rapid acceleration and repeatable positioning are important. The length code B and 100 frame size place the unit in the mid-range of the platform, balancing footprint and force density for general automation tasks. By eliminating rotary-to-linear transmission parts, the axis can avoid backlash and reduce compliance in the motion path.

Its continuous linear output is rated at 1785 N, a level that can be held indefinitely while liquid cooling maintains winding temperature. The force constant is 74.10 N/A, which means each ampere of phase current produces that amount of thrust. During standard duty, the coil draws a rated current of 24.1 A. Resulting copper losses total about 1300 W and are carried away by coolant circulating at 1.9 l/min, allowing sustained operation under load. The phase inductance is 6.5 mH, so current changes are not instantaneous and the drive must account for stored magnetic energy during rapid force commands.

A permanent attraction of 8000 N exists between the forcer and the magnet rail, so the linear guides must withstand that preload, while acceleration peaks can approach 5600 N. Motion profiles may target a nominal travel speed of 350 m/min, and at maximum current the stage can still reach 250 m/min while remaining within its 2.4 min thermal time constant. The 37.5 mm pole width and a voltage constant of 42.7 Vs/m match the electrical behavior expected by compatible Rexroth drive electronics. Because this version does not include an integrated encoder, position feedback must be provided elsewhere in the axis system.
