Product Description:

The MLP140A-0090-FT-N0CN-NQL3 linear motor primary section is produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. This coil assembly generates thrust directly along an iron secondary track, removing the need for rotary-to-linear mechanics in automation cells. It is used in pick-and-place modules, gantry axes, and machining slides where precise positioning and rapid response are required. Because force is produced in a straight line, the axis can avoid backlash associated with screws, belts, or gear reductions.

With a peak attractive force of 7500 N, the motor can hold the secondary rail firmly while delivering acceleration. The magnetic field repeats over a pole width of 37.5 mm, which sets the electrical period and influences cogging behavior. Heat is removed by liquid cooling; coolant enters at 10 bar and fills an internal channel volume of 0.145 l, so a flow of 1.87 l/min maintains thermal balance. Thermo-encapsulation secures the windings against vibration, and winding code 0090 matches the electrical characteristics expected for the 140 frame size. The enclosure has an IP65 rating, which helps block dust and water jets during machine operation.

The cooling circuit introduces only 0.56 bar of pressure drop at nominal flow, allowing connection to compact chillers without requiring oversized pumps. The primary section has a mass of 21.2 kg in the short A-length version, so the mounting structure must carry this static load in addition to the thrust generated during motion. Operation is limited to a secondary track temperature of 70 °C to protect magnet strength and insulation life. No encoder is installed, which allows the machine to use external feedback selected for the required accuracy and travel length. A shielded power cable exits at the front of the housing, helping route the connection through protected cable chains while limiting electromagnetic noise.
