Product Description:

The MLP040B-0250-FS-N0CN-NNNN is a primary part from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. As a liquid-cooled synchronous linear motor element, it mounts along a ferromagnetic secondary track and converts drive current directly into linear thrust for positioning stages, gantries, or transfer modules in automated production. Because thrust is generated directly along the travel axis, the motor avoids rotary-to-linear conversion components such as belts, screws, or rack drives, which helps maintain precise translational motion across the stroke.

This model delivers a continuous thrust of 370 N, so the carriage can maintain constant motion without overheating under nominal duty. That steady force is produced while drawing a rated line current of 5.6 A, which sets the current level for normal thermal loading. Each ampere contributes predictable thrust because the force constant is 66.80 N/A, which supports consistent response during closed-loop operation. The coil back-EMF rises linearly with speed and equals the voltage constant of 38.5 Vs/m, a value used when matching the motor to drive voltage limits. Copper losses that turn into heat are tied to the winding resistance of 6.3 Ω, so the integrated coolant circuit removes I²R heat before temperatures exceed insulation limits.

During rapid indexing the mover can withstand a peak load of 1150 N, and the mechanical system must account for that transient force along the guideway. If motion continues to the top of the curve, velocity can rise to 250 m/min at that maximum thrust, allowing short cycle times on long strokes. The magnetic attraction toward the secondary iron reaches 1700 N, so mounting hardware and bed stiffness must resist that preload without disturbing alignment. Under worst-case electrical and magnetic loading, the coils dissipate 550 W, and the liquid circuit, sized for at least 0.8 l/min of flow with only 0.11 bar pressure drop, keeps winding temperature stable.
