Product Description:

Bosch Rexroth Indramat manufactures the MLP200D-0060-FT-N0CN-NNL4 as part of the MLP Synchronous Linear Motors series. This component is a synchronous linear motor primary section that creates direct electromagnetic thrust along an iron track, replacing rotary motors and mechanical screw drives. It is used in automated transport, pick-and-place, and high-speed machining axes where backlash-free motion and precise positioning are required. Because force is generated directly in the travel direction, the axis can operate without couplings, belts, or ball screws that add compliance to the motion system.

The unit delivers a continuous nominal force of 5,560 N from a rated phase current of 25.2 A. With a force constant of 220.40 N/A, additional current produces proportional thrust. For short bursts, the winding can accept 126.2 A, and magnetic attraction toward the secondary track reaches 25,400 N, so the mounting structure must support that load. Liquid cooling stabilizes temperature as 8.0 L/min flows through a 0.45 L internal duct, causing a 2.4 bar pressure drop while removing 4,969 W of power loss. Heat transfer is improved by a thermo-encapsulation method around the windings. Power leads exit at the front of the housing, and winding code 0060 corresponds to 13.7 mH of inductance and 2.74 Ω of resistance. The 61.3 kg thermal mass helps reduce rapid temperature swings during changing duty cycles.

Dynamic moves are supported by a peak thrust of 17,750 N, allowing acceleration to the nominal travel speed of 140 m/min. When the motor sustains its maximum continuous thrust, carriage velocity is limited to 60 m/min. A thermal time constant of 2.4 min returns the stator to equilibrium quickly after high-load cycles. The primary element is built in motor size 200 and is supplied without an encoder, so external position feedback must be integrated. It mates with matching secondary tracks for direct-drive linear motion and supports machine layouts that avoid gearboxes and rotary-to-linear conversion elements.
