Product Description:

The MLP040B-0300-FT-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series produced by Bosch Rexroth Indramat. As a synchronous linear motor module, it converts drive current directly into linear thrust, eliminating ball screws or belts in pick-and-place gantries, portal axes, and high-speed machining stages. This direct-drive arrangement removes rotary-to-linear transmission elements from the axis and helps limit backlash in the motion path. The moving assembly therefore responds directly to commanded current instead of relying on a screw or belt mechanism to create linear motion. The motor has size 040 with B length, and the 0300 winding variant matches the electrical characteristics used with compatible IndraDrive amplifiers in medium-force applications.

The unit delivers a continuous nominal force of 370 N, enabling sustained carriage movement without overheating. That output is produced when the phase current is held at the rated value of 6.3 A. A force constant of 58.60 N/A means thrust rises proportionally with current, which supports stable closed-loop control. The back EMF increases with speed according to the voltage constant of 33.8 Vs/m. Winding inductance of 28.9 mH and coil resistance of 5.0 Ω at 20 °C affect current rise, voltage demand, and thermal loading during operation.

Dynamic peaks reach 1,150 N for short acceleration intervals when the effective current rises to 36.9 A. Under those conditions, liquid cooling removes the resulting heat, and a flow of 0.8 l/min at an inlet pressure up to 10.0 bar keeps the assembly within its allowable temperature range. The coils are sealed by thermo-encapsulation to resist moisture, and the module weighs 8.1 kg. Attractive magnetic pull toward the secondary track is 1,700 N, the pole width is 37.5 mm, and travel speed can reach 300 m/min at maximum force. Nominal travel speed can reach 500 m/min when commanded by a compatible drive, and because the primary section has no integral encoder, position feedback must be provided externally while the power and sensor leads exit through the front of the coil.
