Product Description:

The MLP300C-0090-FS-N0CN-NNNN belongs to the MLP Synchronous Linear Motors series by Bosch Rexroth Indramat. As a liquid-cooled primary section, it creates direct linear thrust for gantries, machining centers, and high-speed pick-and-place modules, removing the need for rotary-to-linear conversions. The unit's size code 300 indicates its active width, and the standard encapsulation method protects the winding pack from coolant exposure during continuous industrial service. Because the primary section contains the energized winding, the secondary track can remain a passive magnetic element along the travel path. This layout allows the motor to deliver force directly along the axis, which helps reduce backlash and compliance that can appear in mechanical conversion systems.

This model delivers a continuous thrust of 6720 N while sustaining motion up to a nominal speed of 150 m/min; when loaded to full thrust, it reaches 90 m/min. The winding code 0090 is matched to a rated phase current of 35.8 A, and the electrical circuit has an inductance of 7.6 mH with a resistance of 1.56 Ω at 20 °C so the drive can regulate current accurately. Heat generated by copper losses, quantified as 3200 W, is removed through an internal stainless-steel coolant channel. Coolant enters at a maximum pressure of 10 bar and exits with a 2.8 bar pressure drop, while 6.0 mm² power leads are routed through the front of the motor. No encoder is installed, so position feedback must come from an external scale mounted on the axis.

The duty range is extended by a peak current capacity of 205.0 A, which produces a short-term force of 21500 N. Magnetic attraction toward the secondary track reaches 30700 N, so the axis structure must be able to absorb that normal force during operation. The liquid circuit requires 4.6 l/min of flow to keep the stator temperature within the limits of the standard encapsulation. With a transport mass of 62.0 kg, the motor adds substantial weight to the moving or mounted assembly, and lifting provisions may be needed during handling. That loading also affects carriage support and mounting rigidity.
