Product Description:

The MLP140C-0050-FS-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. This linear motor converts stator currents directly into thrust along a flat secondary track, eliminating gearboxes or screw drives. By producing precise linear motion, it serves pick-and-place gantries, portal milling tables, and high-speed transport stages within automated production lines. With a motor size of 140, it balances footprint and force density for medium-load axes.

Under continuous duty, the unit delivers a thrust of 3150 N, which is the continuous nominal force when coolant conditions are met. For rapid acceleration, it can generate up to 10000 N of maximum force in short duty cycles without exceeding thermal limits. The electromagnetic design provides a force constant of 215.9 N/A, so drive current scales predictably with commanded force. Even at full load, the carriage can maintain a maximum velocity of 50 m/min, while the drive current required to sustain the nominal operating point is only 14.6 A. An attractive force of 14,400 N must be considered in rail sizing, and winding code 0050 uses 28.5 mH inductance, which shapes current ripple.

The motor employs liquid cooling, and stainless-steel channels carry coolant through the core with an allowable inlet pressure of 10.0 bar. A flow rate of 2.9 l/min removes the specified 2000 W power loss with a pressure drop of just 1.2 bar. When higher dynamic cycles are commanded, the control can momentarily draw 78.6 A, and back EMF rises in proportion to the voltage constant of 124.6 Vs/m. Despite this demand, the thermal system reaches steady state quickly because the thermal time constant is only 2.4 min. Phase conductors exit at the front face for compact cabinet routing, and a winding resistance of 5.2 Ohm governs steady-state copper losses. Standard encapsulation protects the coils, and no encoder is installed, so external position feedback must be supplied.
