Product Description:

The MLP200C-0130-LT-N0CN-NNNN linear motor primary section is manufactured by Bosch Rexroth Indramat as part of the MLP Synchronous Linear Motors series. It serves as the active force-generating element in industrial automation, producing controlled linear motion without mechanical transmissions. By relying on fixed secondary tracks and an onboard coil assembly, the unit supplies high thrust directly to loads, an approach that reduces wear and increases positioning precision in multi-axis machines, transfer lines, and high-speed handling equipment.

Under continuous duty, the motor delivers a rated thrust of 4460 N, which is the force it can provide continuously without exceeding thermal limits. When energized, the windings dissipate 2900 W of heat, so the integrated water jacket is important for temperature control. Maintaining coolant flow at 4.2 l/min through the 0.358 l channel keeps copper and magnet temperatures within the permitted range while limiting the pressure drop to 1.6 bar. The lamination stack is segmented into poles that repeat every 37.5 mm, which determines electrical commutation and encoder spacing if external feedback is added. The cooling circuit tolerates inlet pressures up to 10.0 bar, allowing operation on closed-loop chillers or plant water services.

For short strokes or acceleration events, the coil can generate up to 14250 N of peak thrust, and the magnetic attraction to the iron secondary reaches 20500 N, so the mounting hardware must withstand both forces. The primary section weighs 50.7 kg, a mass that affects dynamic response and support frame sizing. With a thermal time constant of 2.4 min, temperature stabilizes quickly after load changes, which supports frequent duty-cycle shifts without prolonged cooldown periods. The thermo-encapsulated winding package resists moisture and vibration, and the wire exit at the front simplifies cable routing in tight carriages. The unit does not include an encoder, so external feedback can be selected to match the motion system.
