Product Description:

The MLP300C-0120-FT-N0CN-NNNN is a primary section synchronous linear motor manufactured by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. It generates direct linear thrust for automation axes, replacing mechanical screws or racks in pick-and-place modules, gantry stages, and transfer lines. Liquid cooling is integral to the housing, and the power conductors are routed through the front for compact cable chains. No encoder is installed, so position feedback must be provided by an external scale or resolver selected for the machine.

During continuous duty, the mover produces a thrust of 6720 N, achieved with a rated phase current of 45.2 A and a size 300 coil pack that spans a 37.5 mm pole width. The magnetic circuit delivers this output with a force constant of 148.9 N/A, allowing proportional control when the drive reduces current. Heat dissipated at nominal load reaches 3200 W, so the internal circuit must remove it efficiently. A coolant flow of 4.6 l/min through a channel volume of 0.471 l keeps the winding temperature stable, and the pressure drop across the channel is 2.8 bar. The 4.9 mH winding inductance supports fast current loops, and the translator can run steadily at 180 m/min.

For short bursts, the coil can deliver 21500 N of peak force, limited by a maximum current of 300.0 A from the inverter. Under this overload, the slider may reach 120 m/min, and copper losses remain predictable because the winding resistance is 1.02 ohms. A back-EMF constant of 85.9 Vs/m assists the drive in estimating speed when external sensors are unavailable. Thermal encapsulation supports repeated thermal cycling, and the 74.9 kg primary mass must be accounted for in carriage design. The front-entry wiring layout helps keep cable routing clean without extra junction boxes.
