Product Description:

The MLP100C-0120-FS-N0CN-NNNN is a synchronous linear motor primary segment produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. Acting as the active coil assembly, it delivers thrust directly to a load without gears or ball screws, which simplifies high-speed positioning stages in automated machinery. It is intended for linear axes in assembly lines, cutting tables, and material-handling cells where smooth, programmable force is required. Because thrust is generated directly in the axis, the motor can support precise linear motion without the added compliance of rotary-to-linear transmission components.

A continuous thrust of 2,310 N can be sustained while coolant maintains winding temperature, and a peak of 7,150 N is available for brief accelerations. Each ampere of phase current produces 154.20 N/A of force, so the inverter must provide 15.0 A continuously and may reach 84.9 A during transients. This current-to-force relationship helps the drive regulate thrust directly during acceleration and settling moves. The copper windings have 4.0 Ω of resistance at 20 °C and 22.6 mH of inductance, which affect current rise time and control-loop tuning. The motor has size 100, a pole width of 37.5 mm, and a 1.5 mm² power lead routed through the front housing. Standard encapsulation protects the coil, and because no encoder is installed, the axis requires external feedback for closed-loop positioning.

Liquid cooling removes 1,600 W of loss at nominal load and tolerates inlet pressures up to 10.0 bar. Under this thermal condition, the mover reaches a nominal speed of 190 m/min, while the speed available at full thrust is limited to 120 m/min. A back-EMF gradient of 89.0 Vs/m must be considered when selecting the DC-bus voltage, since generated voltage rises with travel speed. The permanent magnets exert an attractive force of 10,400 N on the ferromagnetic secondary, which influences mechanical clearances and bearing design.
