Product Description:

The MLP140B-0090-FT-N0CN-NNNN linear motor primary part is produced by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. It converts drive current directly into thrust along a magnetic track, eliminating mechanical couplings in automation axes that need precise, repeatable linear motion. The assembly uses motor size 140 and length code B, so its physical envelope matches standard secondary tracks offered for this series and supports integration into pick-and-place modules, gantries, and machining tables.

The mover develops a continuous thrust of 2415 N and reaches a peak of 7650 N, while an additional attractive load of 11,000 N must be absorbed by the guidance mechanics. A force constant of 172.80 N/A links drive current to usable linear force, while winding resistance is 2.6 Ω and the voltage constant is 99.7 Vs/m. Pole width is 37.5 mm, and winding code 0090 corresponds to the motor's electrical winding. The motor can sustain a nominal travel speed of 160 m/min and still deliver rated thrust, while speed at maximum force is limited to 90 m/min. Continuous winding losses must be removed by the cooling system during operation. An external encoder is not included, so the application must supply position feedback by other means.

Heat is removed through a liquid cooling jacket that circulates coolant at 3.6 l/min; pressure drop across the channels is 0.9 bar, and inlet pressure may not exceed 10 bar. The internal duct holds 0.214 l of fluid, and total dissipation to be carried away is 2512 W. The motor mass is 30.1 kg, giving the mover substantial thermal inertia without overly increasing carriage load. A thermo-encapsulation method protects the windings, and electrical leads exit at the front for straightforward routing. Phase inductance of 14.2 mH shapes current ripple and should be considered when tuning the drive amplifier.
