Product Description:

The MLP140A-0030-FT-N0CN-NNNN is a primary coil section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. This linear motor element produces thrust directly along a flat secondary track. It allows automated gantry axes and pick-and-place units to move without gearboxes, belts, or ball screws, which reduces mechanical transmission parts in the drive train.

It delivers a continuous nominal thrust of 1680 N when the drive supplies a rated phase current of 5.0 A. The electromagnetic design provides a force constant of 337.6 N/A, enabling predictable force control from current commands. Integrated liquid cooling removes heat through an internal channel that accepts inlet pressures up to 10.0 bar, so the motor can run continuously at its nominal rating. A voltage constant of 194.9 Vs/m indicates the back EMF the inverter must overcome during motion. Power conductors exit through the front of the housing, and a thermo-encapsulation method secures the windings against vibration. The pole width is 37.5 mm, the mechanical frame is size 140 with length code A, and no encoder is installed, so external position feedback is required. External feedback lets the axis use a separate measuring system when position accuracy must be referenced to the machine structure.

During short overloads, the coil can generate a peak thrust of 3000 N with a maximum phase current of 10.5 A, while the magnetic attraction toward the secondary track reaches 7500 N. Travel speed is limited to 30 m/min at that peak load, whereas nominal operation supports 75 m/min. To maintain thermal balance, the cooling circuit must provide 1.9 l/min of fluid, and the copper mass reaches steady-state temperature within 2.4 min. Dynamic response is influenced by a winding inductance of 20.2 mH and a resistance of 3.6 Ω, which affect current rise time and drive voltage demand.
