Product Description:

The MLP100K-0040-FT-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. As a liquid-cooled linear motor, it is intended to generate direct linear thrust for high-speed positioning stages, eliminating mechanical transmissions found in rotary-to-linear conversions. Integrating this primary part into a matching magnetic track lets the system drive heavy tooling or workpieces with consistent force along the stroke, making it suitable for gantry axes, palletizers, and material-handling equipment that benefit from precise, lower-maintenance linear motion.

The motor delivers a continuous thrust of 1480 N at its rated operating point, while short bursts can reach a peak of 4675 N for rapid acceleration. Achieving these outputs requires a phase current of 6.3 A nominally and up to 33.6 A when the application commands maximum force. Linear travel speed under nominal loading is 135 m/min, and the back EMF generated per unit velocity has a constant of 136 Vs/m. Liquid cooling removes 1150 W of copper and iron losses, and the circuit needs 1.6 L/min of coolant flow to maintain thermal equilibrium. Force production per ampere is 235 N/A, providing a direct current-to-force relationship.

Under no-load conditions, the magnetic attraction toward the secondary track reaches 6413 N, so the mechanical guide system must absorb that force. The electromagnetic structure follows winding code 0040 and a pole pitch of 37.5 mm, which pairs with the matching Rexroth magnet rail. Stator impedance is influenced by a winding inductance of 63.6 mH and a resistance of 12.1 Ω at 20 °C, which affects current ripple and servo loop bandwidth. The unit is potted with a thermo-encapsulation method for vibration damping, weighs 20.3 kg, and uses front-routed conductors because no encoder is installed onboard.
