Product Description:

The MLP200C-0170-FT-N0CN-NNNN is a linear primary module manufactured by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. It serves as the moving component of a direct-drive positioning axis, producing translational force without belts, screws, or gearboxes. By acting directly on the secondary track, the motor supports high-speed material handling, printing heads, and multi-axis gantries that require accurate linear motion under changing loads.

During continuous operation, the module delivers 4460 N of thrust while drawing a rated phase current of 35.6 A. The electromagnetic efficiency behind that output is shown by its force constant of 125.30 N/A, so each ampere supplied by the drive produces that amount of linear force. Back EMF generated during motion is quantified by a voltage constant of 72.3 Vs/m, a value used for sizing the DC bus and protection circuitry. Heat generated by copper losses, listed at 2700 W, is removed through a jacket that uses liquid cooling; the hydraulic circuit must maintain a flow of 3.9 l/min to keep winding temperatures within limits. A pole width of 37.5 mm sets the magnetic pitch, and a winding inductance of 5.7 mH helps moderate current ripple during commutation.

The dynamic envelope extends to a peak thrust of 14250 N, available for rapid acceleration profiles when the drive can momentarily supply a maximum phase current of 162.6 A. Electrical losses across the copper paths are governed by a winding resistance of 1.08 Ω at 20 °C, which affects thermal rise and servo amplifier sizing. Attractive force toward the track reaches 20,500 N, so mounting hardware must withstand that preload, and the assembly sustains 10 bar inlet pressure in its coolant circuit. With a maximum travel speed of 220 m/min and a speed of 170 m/min at full load, the unit is suited for high-throughput machinery with short cycle times.
