Product Description:

The MLP100B-0120-FT-N0CN-NQNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. It delivers direct linear thrust for gantry loaders and pick-and-place axes without belts or ball screws. The unit has motor size 100 and length code B, and its thermo-encapsulation method helps shield the windings from mechanical stress. Power conductors are routed through the front of the housing, and the axis relies on an external position feedback device because no encoder is installed.

A liquid cooling jacket maintains stable operation by limiting surface temperature rise to 2 K when coolant flow reaches 1.9 L/min and inlet pressure stays below 10.0 bar. Under these thermal conditions, the primary section sustains a continuous nominal force of 1785 N, while its magnetic circuit produces an attractive force of 8000 N on the secondary track that must be absorbed by the machine structure. The drive can surge to a maximum force of 5600 N for short acceleration periods, and its electromechanical conversion is characterized by a force constant of 146.3 N/A. Supplying the stator with a rated current of 12.2 A through 2.5 mm² power leads allows the carriage to reach a nominal velocity of 190 m/min, while the 23.3 kg thermal mass helps damp rapid temperature swings.

For dynamic bursts, the stator can be driven up to a maximum current of 71.2 A, which is limited by the magnetic circuit and thermal design. Back electromotive force rises at a voltage constant of 84.4 Vs/m, so the servo drive must provide enough DC-bus margin at higher travel speeds. Current response is influenced by a winding inductance of 25.6 mH, while steady-state copper losses follow from a winding resistance of 4.5 ohms; together these values support current-loop tuning and smooth linear motion.
