Product Description:

The MLP070B-0120-FS-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series developed by Bosch Rexroth Indramat. As a linear motor stator, it delivers direct linear thrust for pick-and-place axes, gantries, and machining tables where rotary-to-linear conversions are undesirable. The part works with a passive magnetic track to translate drive current into force, streamlining precision motion tasks in automated cells.

During continuous operation, the section sustains a thrust of 820 N when liquid coolant keeps the winding temperature under control. To support that rating, it draws a steady phase current of 5.9 A, while the coil has a winding inductivity of 55.3 mH and a resistance of 9.2 Ω. Heat leaves through internal channels that pass coolant at 1.3 l/min; this liquid-cooling circuit is mandatory because the encapsulated windings occupy a compact 070 size housing. Magnetic interaction uses a pole width of 37.5 mm, and the force constant is 138.80 N/A, meaning each additional ampere supplies nearly 139 N of thrust. Its back-EMF slope is set by a voltage constant of 80.1 Vs/m, so the selected drive must tolerate the generated voltage at speed. Power wiring enters from the front through 1.0 mm² conductors, and no encoder is installed, so an external feedback device is required.

For short bursts, the winding accepts a peak current of 42.8 A, enabling a maximum force of 2600 N for periods limited by the 2.4-minute thermal time constant. When exposed to the attractive force of 3750 N, the carriage must be guided to prevent pull-in on the track. Nominal traverse speed reaches 220 m/min, while 120 m/min is available under full load. The primary part mass is 10.4 kg, matching the B length code and influencing servo-loop inertia calculations. Standard encapsulation protects the windings, and the absence of an integrated encoder keeps the overall envelope compact.
