Product Description:

The MLP200B-0040-FT-N0CN-NNL3 is a synchronous linear motor primary section from Bosch Rexroth Indramat in the MLP Synchronous Linear Motors series. It delivers direct thrust for gantries and transfer stations. Physical features include motor size 200, length code B, and a thermo-encapsulated mass of 40.0 kg. Cooling is provided by a liquid circuit, and power leads exit the front face. This version has no integrated encoder, so position feedback must come from an external measuring device on the axis. Because force is produced directly along the travel path, the drive can support smooth linear motion on fast-travel axes.

The mover develops an attractive force of 15600 N, which is the magnetic preload that the guide system must withstand. Under continuous duty, it supplies 3465 N of thrust, and that level is limited by 2200 W of winding power loss removed by the coolant. A force constant of 251.4 N/A links thrust to phase current, so the rated phase current of 13.8 A produces nominal force without overheating. With a voltage constant of 145.1 Vs/m, the inverter must generate matching back EMF during motion. Electrical behavior is set by a winding resistance of 5.7 Ω and an inductivity of 29.7 mH, which correspond to winding code 0040. The pole width is 37.5 mm, and the internal leads use a conductor cross-section of 1.0 mm².

The assembly can generate 10900 N of peak thrust during short duty cycles, provided the inverter can momentarily supply 74.2 A per phase. Nominal velocity reaches 100 m/min under rated conditions, while speed at the maximum force point is limited to 40 m/min. The coolant circuit must move 3.2 l/min to stabilize temperature during these transients and keep the thermo-encapsulated winding package within its insulation class. Short bursts at this level are used for acceleration on transfer axes where force demand briefly rises above the continuous level. Stable coolant flow also helps reduce thermal buildup during repeated cycles.
