Product Description:

Bosch Rexroth Indramat supplies the MLP200B-0120-FT-N0CN-TQNN primary section for linear direct-drive axes in the MLP Synchronous Linear Motors series. The unit has a size 200 active width with a B length code, and its iron core weighs 40.0 kg. By generating thrust directly along the machine slide, it eliminates rotary conversions and is suited for applications that require precise positioning with reduced mechanical wear. Power conductors are routed through the front of the housing, which helps keep cable loops short inside compact automation modules.

During continuous operation, the mover produces 3465 N of thrust while drawing a rated current of 21.8 A. The force-to-current relationship is set by a drive constant of 159.30 N/A, giving the controller predictable current commands. With a nominal velocity of 190 m/min, the section supports high-speed pick-and-place motion, and its copper generates back EMF at 91.9 Vs/m. Thermal energy is removed through an internal channel that uses liquid cooling, helping the laminations remain within their intended operating range. The windings have an inductance of 12.1 mH and a resistance of 2.34 Ω at 20 °C, which affects the drive’s current loop behavior. A thermo-encapsulation method protects the coils from vibration, the 2.5 mm² power leads match the nominal current, and no encoder is installed, so position feedback must be supplied externally.

For short bursts, the mover can deliver a maximum thrust of 10 900 N and accept up to 128.6 A from the inverter. Its magnetic circuit produces an inherent attractive force of 15 600 N toward the secondary track, so the mechanical guides must withstand this preload. When driven to rated force, the carriage reaches 120 m/min, which limits speed under peak load. The assembly has a thermal time constant of 2.4 min, showing that its temperature responds quickly to changes in load.
