Product Description:

The MLP100B-0120-FS-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. This linear motor generates direct linear thrust for precision positioning stages and conveyor axes in industrial automation, eliminating the need for ball screws or belts. It works as the active component that, when combined with a passive secondary track, delivers repeatable force and velocity for high-speed assembly and machining equipment.

Motor size 100 gives the motor a 100 mm wide active surface, while length code B extends the coil set for additional stroke capability. Under rated conditions, the coil produces a 1785 N continuous force, and this output is reached at a 12.2 A rated current. The electromagnetic conversion efficiency is characterized by a force constant of 146.30 N/A, meaning each ampere generates that amount of thrust. An 84.4 Vs/m voltage constant sets the back EMF that the drive must overcome during motion. The stator phase resistance is 4.5 Ω at 20 °C, and the inductance is 25.6 mH, which shapes current loop response. Power conductors exit at the front of the housing, and the 2.5 mm² wire cross-section supports the thermal load of the copper paths. Standard encapsulation protects the winding pack against moisture and vibration.

For startup or short bursts, the motor can deliver a 5600 N peak force, while the passive iron creates an 8000 N attractive force that must be considered when designing the air gap. Liquid cooling channels run through the frame; with a 1.9 l/min flow, the system dissipates 1300 W of losses while experiencing only 0.5 bar pressure drop and tolerating up to 10 bar inlet pressure. At that flow, the unit sustains its thermal limits so it can reach a nominal velocity of 190 m/min, or 120 m/min when loaded at maximum force. A maximum phase current of 71.2 A is permitted for transient events. Because no encoder is installed, external position feedback must be provided to the drive.
