Product Description:

The MLP140B-0035-FS-N0CN-NNNN is a primary section in the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. It mounts on a ferromagnetic secondary track, where its moving coil produces direct linear force without gearboxes, couplings, or ball screws. As the active element of a linear servo system, the unit supplies controlled thrust for pick-and-place axes, portal stages, machine-tool feed drives, and other positioning tasks that require smooth translational motion.

The drive generates a continuous thrust of 2415 N, sustained while the coil moves at its nominal speed of 85 m/min. This operating point is reached when the windings draw a rated current of 7.7 A, and the voltage constant is 66.5 Vs/m. Magnetic design gives the mover a force constant of 313.6 N/A, so each ampere above the rated value increases axial force in direct proportion. A winding inductance of 80.0 mH shapes current rise times, and the 0035 winding arrangement is installed in a size 140, length B coil. The pole width is 37.5 mm, which matches standardized secondary segments used in the motor system. Wire leads exit at the front through standard encapsulation for straightforward cabinet routing. During nominal operation, the coil releases 2512 W of heat, and removing this heat requires a coolant flow of 3.6 l/min. The unit uses 1.0 mm² power conductors and is supplied without encoder feedback.

The linear motor can reach a peak thrust of 7650 N for short bursts when supplied with a maximum current of 41.3 A. In this overload range, velocity is limited to 35 m/min, and copper temperature is controlled by the integrated liquid cooling channel. Coolant enters the mover at pressures up to 10.0 bar and leaves with a pressure drop of 0.9 bar across the circuit. Electrical losses are moderated by a winding resistance of 15.9 Ohm, which helps limit thermal gradients during acceleration ramps and repeated high-force moves.
