Product Description:

The MLP300C-0090-FT-N0CN-NNL3 is the primary part of a synchronous linear motor manufactured by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. It converts three-phase drive current directly into thrust along a magnetic track, giving automation axes high speed and repeatable positioning without gearboxes or ball screws. This construction supports gantries, palletizers, and other equipment that benefit from electronic motion control over long strokes.

The motor’s electromagnetic output is characterized by a continuous nominal thrust of 6720 N, available across the full travel range at the rated coolant temperature. With a force constant of 187.90 N/A, each ampere delivered by the drive contributes nearly 188 newtons of linear force, so current demand remains predictable during closed-loop control. The inverter can supply a phase current of 35.8 A, matching the winding geometry identified by code 0090 and frame size 300. Electromagnetic dynamics are further shaped by a winding inductivity of 7.6 mH, which limits current rise and reduces conducted noise, while a winding resistance of 1.56 Ω contributes to copper loss during steady operation. The motor has a nominal travel speed of 150 m/min and no onboard encoder, so external feedback is required for closed-loop control.

During transients, the stator can accept a peak phase current of 205.0 A, enabling a maximum thrust of 21500 N for rapid acceleration. At that overload point, the carriage still reaches 90 m/min, keeping force delivery nearly constant up to this velocity ceiling. Liquid cooling circulates through internal channels, and the circuit requires 4.6 L/min of flow with a maximum inlet pressure of 10 bar and an approximate pressure drop of 2.8 bar to remove 3200 W of heat. The thermo-encapsulated windings withstand an attractive normal load of 30700 N, while the front-fed power leads simplify cable management. The primary mass is 74.9 kg, and the voltage constant is 108.4 Vs/m.
