Product Description:

The MLP140B-0090-FS-N0CN-NNNN linear primary part is produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. Designed for position-controlled gantries, pick-and-place systems, and machine axes, it generates thrust directly along the travel path and eliminates rotary-to-linear conversions. Motor size 140 with length code B sets the active cross-section that mates with standard secondary tracks, and liquid ports along the flank connect the unit to closed-loop coolant circuits used in high-duty automation lines.

During continuous operation, the mover delivers 2415 N of thrust while drawing a rated current of 14.0 A. The force constant is 172.80 N/A, so each ampere produces about 173 newtons under steady thermal conditions. The back-EMF gradient is 99.7 Vs/m, and the copper path has 2.6 Ω of resistance with 14.2 mH phase inductance, which affects drive sizing and current-loop tuning. To remove 2,512 W of power loss, the coil assembly uses liquid cooling that requires 3.6 L/min at a maximum inlet pressure of 10.0 bar. Coolant is routed through front-fed hoses, which helps keep thermal expansion balanced within the standard encapsulated housing and reduces force derating.

The mover can withstand peak demands up to 7650 N and accepts momentary currents of 79.3 A for rapid acceleration. Under rated excitation, it travels at a nominal speed of 160 m/min, while the maximum speed at full load is limited to 90 m/min. Structural mass is 24.5 kg, and the attractive magnetic force toward the secondary track reaches 11,000 N, which affects bearing selection and safety spacing. A 2.4-minute thermal time constant allows frequent start-stop cycles without exceeding insulation limits. Winding code 0090 corresponds to the electrical layout, no encoder is installed, and the front-routed conductor scheme simplifies cable chains in compact machinery.
