Product Description:

The MLP200C-0130-LS-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series produced by Bosch Rexroth Indramat. As a liquid-cooled linear motor, it delivers direct thrust along a track without mechanical transmission components, making it suitable for pick-and-place axes, gantries, or high-speed machining tables. Its role in automation is to convert electrical drive current into linear motion with high force density while keeping thermal loads under control through an internal coolant circuit.

This model can exert an attractive force of 20500 N between the primary and secondary tracks, enabling stiff carriage control even under heavy process loads. Under rated force, the moving assembly can reach a maximum speed of 130 m/min, which helps shorten cycle times on long strokes. Continuous operation generates up to 2900 W of heat, so the integrated liquid channels must be supplied with a flow of 4.2 l/min to remove excess energy. At that flow rate, the coolant experiences a pressure drop of 1.6 bar, which the machine-side pump must overcome while maintaining the pressure-drop constant of 0.13. Electrical power is fed through a high-flex shielded cable that exits the front of the housing, and the windings are protected by a standard encapsulation method. There is no length-measuring system or motor encoder installed, so position feedback must be provided by an external scale.

The cooling loop encloses only 0.203 l of fluid, allowing fast purging and minimal coolant inventory. Magnetic interaction is established across a pole width of 37.5 mm, which matches the secondary track geometry and sets the spatial commutation period. A thermal time constant of 2.4 min lets the drive respond quickly to load changes without large temperature excursions. The primary weighs 42.0 kg, reflecting its size code 200 and the internal copper content needed for the stated heat loss. The front cable exit helps simplify routing where side clearance is limited, and the motor body remains focused on thrust production and liquid cooling rather than integrated feedback hardware.
