Product Description:

The MLP140C-0050-FT-N0CN-NNNN is a synchronous linear motor segment built by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. Installed on a fixed secondary track, it generates direct linear thrust for pick-and-place modules, portal axes, or machining tables without using ball screws or belts. By replacing rotary-to-linear conversions, the unit improves positioning accuracy and reduces wear in industrial automation cells.

Thermal management is handled by liquid cooling, which requires a coolant flow of 2.9 L/min and produces a pressure drop of 1.2 bar through the internal circuit. During continuous operation, the windings release 2000 W that must be transferred to the coolant to avoid derating. The electromagnetic circuit draws a rated phase current of 14.6 A, yet the drive can supply up to 78.6 A for short bursts. With a force constant of 215.9 N/A, this current range yields a nominal thrust of 3150 N and peak thrust up to 10000 N. The back EMF rises proportionally to speed at 124.6 Vs/m, which the servo amplifier uses for velocity control. Copper loss is influenced by a 5.2 Ω winding resistance, and winding code 0050 identifies the conductor geometry and thermal limits.

The mover’s passive magnetic coupling produces an attractive load of 14400 N, so the guidance system must keep the air gap stable during acceleration. Dynamic response is influenced by a winding inductance of 28.5 mH, which slows current rise and helps smooth force ripple at high slew rates. The section reaches a nominal travel velocity of 110 m/min at rated current, while maximum thrust limits the achievable speed to 50 m/min. Motor size 140 sets the active width, and the liquid lines exit toward the front together with the power conductors because the electrical connection is routed through that face. A thermo-encapsulation method seals the coil system, and no encoder is installed, so position feedback must be provided by an external scale.
