Product Description:

The MLP070C-0120-FS-N0CN-TQ01 is a primary section in the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. It produces electromagnetic thrust without mechanical conversion, so it can replace ball screws or rack-and-pinion stages in automated assembly cells, gantry axes, and high-speed machining centers. Because motion is generated directly along the travel path, the axis can avoid backlash from intermediate transmission components. Standardized mounting dimensions help the section fit common machine layouts without custom adapter plates. The size code 070 indicates the active coil width used when this stator is paired with the matching secondary track.

During continuous operation, the section delivers a linear force of 1200 N, while short bursts can reach a peak of 3800 N. An attractive force of 5500 N acts between the primary section and the steel track during operation. With a rated phase current of 9.2 A, the winding produces nominal thrust, and drive amplifiers may supply up to 56.9 A during acceleration phases. Nominal process speeds can reach 180 m/min, although full-force operation is limited to a lower travel speed. Liquid cooling removes copper and iron losses, and the windings dissipate 1100 W of heat that must be carried away to maintain thermal balance. Power leads and temperature-sensor wiring exit on the front side to simplify cable chain routing.

The embedded stainless tubes support the cooling circuit, and a pole pitch of 37.5 mm sets the magnetic wavelength along the motor. The coolant path has a pressure drop of 0.4 bar at a minimum flow rate of 1.6 L/min, while the standard encapsulation protects the coils from immersion. The winding resistance is 5.7 ohms, which supports predictable electrical losses and stable current control. No encoder is installed, so position feedback must be provided by an external scale. The front-side cable outlet also allows disconnection without routing cables around the machine frame.
