Product Description:

The MLP070C-0120-FT-N0CN-NNNN primary section is a linear motor delivered by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. As an iron-core synchronous design, it generates direct linear thrust for gantries, pick-and-place axes, and high-speed machining tables, eliminating ball screws or belt drives. In an automation cell, it cooperates with a passive secondary track and a drive controller to translate stator current into controlled force and velocity for precise point-to-point positioning.

Under steady load, the unit supplies a continuous force of 1200 N, allowing the axis to carry fixtures or workpieces without thermal overload. When current reaches the rated value, a back-emf coefficient of 75.2 Vs/m describes the voltage produced per meter of speed, which the drive must overcome during operation. Transient moves can draw up to 56.9 A, giving access to a peak thrust of 3800 N for acceleration or brief force spikes. During such duty cycles, it dissipates 1100 W as resistive and core losses, so the liquid circuit must remove heat. A coolant flow of 1.6 l/min through the internal channel maintains winding temperature within design limits.

The magnetic assembly exerts an attractive load of 5500 N on the secondary track, which is a consideration for bearing sizing. Stator windings exhibit an inductance of 31.132 mH, shaping current-loop bandwidth, while a resistance of 5.7 Ω at 20 °C sets the copper loss baseline. Environmental sealing meets the IP65 class, enabling installation in cutting fluid or dust-laden zones when hoses and wiring are routed through the front face. The motor’s force constant of 130.4 N/A links commanded current to linear thrust, supporting velocity profiles up to the nominal 180 m/min and 120 m/min at maximum force even without an encoder. Thermo-encapsulation shields the coils, and the liquid cooling path matches the 070 size footprint.
