Product Description:

The MLP200B-0040-FT-N0CN-NNNN linear motor is produced by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. It is a primary segment that delivers direct thrust along an iron track for gantry axes, pick-and-place modules, and similar positioning tasks in automated equipment. Motor size 200 and length code B indicate its active area, while the unit’s liquid-cooled stator helps keep thermal expansion low during continuous duty. Because thrust is produced directly along the axis, the motor avoids backlash from belts, screws, and gear trains.

The motor supplies a continuous thrust of 3465 N at a nominal velocity of 100 m/min and can reach a peak thrust of 10900 N for short acceleration periods. Each ampere of phase current produces a force of 251.40 N/A, giving predictable load calculations. The drive normally delivers a phase current of 13.8 A, yet the control electronics can command up to 74.2 A for rapid moves when the cooling system can remove the added heat. Winding code 0040 corresponds to coil geometry with an inductance of 29.7 mH and a resistance of 5.7 Ω at 20 °C. Under full excitation, the mover can still travel at 40 m/min while producing maximum force, and the stator dissipates 2200 W that must be removed by the cooling circuit.

The magnetic attraction to the secondary track reaches 15600 N, so the machine structure must resist substantial normal force in addition to the moving load. Liquid cooling requires a flow of 3.2 l/min with inlet pressure not exceeding 10 bar, and heat passes through internal channels formed by a thermo-encapsulation method that also protects the windings. Total mover mass is 40.0 kg, which affects system inertia and support rail sizing. Power cables are routed through the front of the housing, and no encoder is installed, so position feedback must come from an external scale system. A voltage constant of 145.1 Vs/m corresponds to the back-EMF used in drive sizing and regenerative calculations.
