Product Description:

The MLP070C-0300-FS-N0CN-NNNN linear motor primary section is built by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. Mounted along a magnet track, it converts stator current directly into thrust, eliminating rotary-to-linear mechanics in high-speed automation. The design follows motor size 070 and winding code 0300, aligning the electrical parameters with companion drive modules. With this configuration, the unit serves gantries, pick-and-place modules, or transport lines that demand precise force control along extended strokes. Direct linear drive operation also reduces the need for couplings, belts, or screw mechanisms in axes that prioritize repeatable motion.

Under continuous duty, the mover delivers 1200 N of thrust, a value that results from its electromagnetic gap and copper use. A force constant of 65.2 N/A links generated force to phase current, while an unpowered attractive pull of 5500 N must be handled by the mechanical guideway. Electrical loading is governed by a rated phase current of 18.4 A, and each meter of travel induces back-EMF at 37.6 Vs/m. The three-phase coils present 10.2 mH of inductance and 1.46 Ω of resistance at 20 °C, matching the assigned winding group. Power enters through 2.5 mm² conductors routed from the front of the housing, and no encoder is installed, so position feedback must be supplied by an external device.

Thermal management relies on liquid cooling, removing up to 1100 W of copper and iron losses through a 1.6 l/min coolant flow. With a thermal time constant of 2.4 min, the motor heats and cools quickly, which helps the axis respond to changing load cycles with less thermal delay. During transients, it can accept 106.7 A to reach a peak thrust of 3800 N. The carriage mass of 14.3 kg helps damp vibration while still supporting nominal runs at 450 m/min and bursts of 300 m/min at full load. Standard encapsulation seals the windings, and the liquid circuit helps carry heat away from the active section during repeated acceleration and deceleration.
