Product Description:

The MLP140B-0090-FT-N0CD-NNNN is a primary section in the MLP Synchronous Linear Motors series from Bosch Rexroth Indramat. This synchronous linear motor converts electrical current directly into linear thrust, removing mechanical transmissions in pick-and-place gantries, transport shuttles, and machining tables. Motor size 140 and length code B place the unit in the middle range of the family, giving a practical balance between installation space and usable force for general industrial automation tasks. Because force is generated directly along the axis, the drive train can avoid backlash from rotary-to-linear transmission components and respond smoothly to rapid position changes.

The motor has a continuous nominal thrust of 2415 N, which the coil can sustain when cooling limits are observed. For transient moves, the motor delivers up to 7650 N. Each ampere supplied yields about 172.80 N/A, linking drive current to linear force. The stator draws 14.0 A under rated load, while the protective limit of 79.3 A must be considered when selecting a compatible inverter. Winding code 0090 corresponds to a resistance of 2.6 Ω and an inductance of 14.2 mH, and a voltage constant of 99.7 Vs/m relates back EMF to travel speed. The windings are secured by thermo-encapsulation, and no encoder is installed, so the axis requires an external feedback device for position control.

Motion performance reaches a nominal speed of 160 m/min, while the maximum speed under full thrust is 90 m/min. An attractive magnetic load of 11000 N acts between the primary and secondary tracks, so the guide system must support that force during operation. Internal copper losses total 2512 W and are removed by liquid cooling, with 3.6 l/min of coolant flowing through the channel at a pressure drop of 0.9 bar. The thermal time constant is 2.4 minutes, which shows that the temperature changes quickly as the load changes. A pole width of 37.5 mm matches the magnet rail pitch, and the lack of an integrated encoder leaves flexibility in the choice of an external measuring system.
