Product Description:
The MLP140A-0120-FS-N0CN-NNNN is a primary section produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. With size code 140, this stator module travels over a permanent-magnet track to convert three-phase drive current into linear motion for gantries, handling systems, and machining tables. The A length code indicates its active coil length, while an internal liquid circuit replaces separate heat sinks and fans. By eliminating ball screws or gearboxes, the motor supports direct, backlash-free positioning in installations that demand high dynamics and reduced mechanical wear within an automation cell.
Under continuous operation, the primary section generates 1680 N of thrust at a nominal speed of 190 m/min when the winding carries a rated current of 12.1 A. The electromagnetic conversion is characterized by a force constant of 138.50 N/A and a voltage constant of 79.9 Vs/m, allowing the drive controller to calculate feed-forward voltage accurately. Winding values of 23.1 mH inductance and 4.3 Ω resistance limit ripple current and set the current loop bandwidth. Intermittent peaks reach a maximum phase current of 70.8 A, while the thermal design limits total power dissipation to 1300 W as long as coolant flow remains within range.
The liquid-cooling circuit accepts inlet pressures up to 10.0 bar and achieves the required heat extraction with only 1.9 l/min of flow, producing a pressure drop of 0.6 bar through the channels. During stall or acceleration events, the motor can supply up to 5200 N of dynamic thrust while still moving the axis at 120 m/min, and the permanent magnets exert an attractive force of 7500 N on the secondary rail that must be considered in the machine structure. The assembly weighs 17.0 kg, uses front-routed power wires for streamlined cabling, and has a standard encapsulation method that protects the windings. No encoder is installed, so position feedback must come from an external scale.
