Product Description:

The MLP300C-0060-FT-N0CN-NNNN is a primary section in Bosch Rexroth Indramat's MLP Synchronous Linear Motors series. A motor size of 300 allows direct thrust along a track, removing gear stages in pick-and-place gantries, machining tables, and other automation axes. Liquid-cooled windings and thermo-encapsulation support high force density in a compact body. The module mates with a separate secondary rail and a drive amplifier for closed-loop positioning.

Beneath the encapsulated windings, the mover delivers a continuous force of 6,720 N at the rated current of 29.6 A, which is the steady thrust available for constant-duty motion. When process acceleration demands increase, the drive can momentarily draw a peak of 143.1 A without exceeding coil limits. A pole width of 37.5 mm sets the magnetic period and contributes to an attractive load of 30,700 N between the primary and the steel track. Heat generated by 3,200 W of power loss is removed through a coolant stream of 4.6 l/min, which is supported by the integrated liquid-cooling circuit. A back-EMF constant of 130.9 Vs/m indicates the voltage the amplifier must counter during fast moves. Conductors exit at the front, the 0060 winding provides 11.4 mH inductance and 2.4 Ω resistance, and no encoder is installed, so external feedback is required.

During transients, the assembly can generate up to 21,500 N of peak thrust, and its force constant of 226.90 N/A converts drive current into linear motion. With adequate stroke length, the unit reaches a rated travel speed of 110 m/min; if it runs at peak load, the velocity must be limited to 60 m/min to remain within mechanical limits. The cooling jacket and the 74.9 kg mass give the mover a thermal time constant of 2.4 min, so coil temperature responds quickly to power changes. The attractive preload remains higher than the dynamic forces, and the thermo-encapsulation helps protect the windings from coolant ingress.
