Product Description:

Bosch Rexroth Indramat manufactures the MLP200D-0120-FS-N0CN-NNNN primary section for the MLP Synchronous Linear Motors series. As a moving-coil assembly, it generates direct thrust along a magnet track, eliminating mechanical transmissions in pick-and-place axes, gantry stages, and high-speed machining centers. The motor converts drive current into linear force, allowing the control system to position loads rapidly and with repeatable accuracy in automated equipment. Because thrust is produced directly in the axis, the drive avoids the backlash and compliance that can come from rotary-to-linear transmission components.

A force constant of 117.3 N per A converts each ampere into thrust, and the continuous phase current is 47.5 A. With a winding resistance of 0.74 ohms, the motor produces 3700 W of loss that must be removed during operation. The module uses liquid cooling, and a coolant flow of 5.2 L/min keeps coil temperature within limits. Conductors exit at the front, and a standard encapsulation method secures the windings. Electrical behavior includes a voltage constant of 67.6 Vs/m, an inductance of 4.1 mH, and a peak current capability of 201.5 A. Hydraulic data list a pressure-drop constant of 0.137, which corresponds to 2.45 bar at minimum flow. The size-200 frame matches a 37.5 mm pole width, and the motor is supplied without an encoder.

During operation, the primary section is pulled toward the magnet track by an attractive load of 25400 N, so the linear guides must support that preload. Under continuous excitation, it reaches a nominal speed of 190 m/min, and at full thrust the velocity reaches 120 m/min. Heat transfers to the coolant quickly, as shown by a thermal time constant of 2.4 min. Sealing to IP65 helps protect the unit from dust and low-pressure water on open machine frames. The primary section is intended for use with the corresponding magnet track in linear-axis assemblies.
