Product Description:

The MLP300C-0060-FS-N0CN-NNL4 is a primary section in the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. Mounted on a moving carriage, this component converts three-phase drive current directly into linear thrust, so the axis can operate without belts, screws, or gearboxes. This direct-drive arrangement is well suited for packaging axes, gantry loaders, and high-speed machine-tool stages that require fast point-to-point positioning and consistent motion.

Liquid cooling circulates through internal channels to keep winding temperature stable while the mover delivers a continuous nominal thrust of 6720 N at the rated operating point. A force constant of 226.90 N/A links current command to produced force, and with a continuous phase current of 29.6 A, the drive electronics can hold a load without drift. The 0060 winding code, paired with size 300 laminations, gives the motor an inductance of 11.4 mH and a resistance of 2.4 ohms, which influence current response and electrical loading. The voltage constant is 130.9 Vs/m, so motion at 1 m/s induces that back EMF level for the inverter to overcome. For acceleration bursts, the coils can accept 143.1 A, and at the nominal velocity of 110 m/min the motor remains within thermal steady state.

During transient moves, the stator can generate a peak thrust of 21500 N, while magnetic attraction toward the secondary rail reaches 30700 N, so the mechanical guidance system must absorb that preload. Dissipated copper and iron losses are limited to 3200 W and are removed by the coolant, while the standard encapsulation helps shield the windings from process contaminants. The assembly has a thermal time constant of 2.4 min, so temperature responds quickly to duty-cycle changes instead of building slowly over a long interval. Power enters through 4.0 mm² conductors routed through the front face, and because no encoder is installed, external position sensors must close the motion loop.
