Product Description:

The MLP300C-0060-FT-N0CN-NNL4 is a synchronous linear motor primary section manufactured by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. It produces thrust directly along a machine axis so linear guides, pick-and-place gantries, or portal stages can position loads without mechanical gearboxes. By eliminating rotary-to-linear conversions, the unit shortens cycle times and maintains positioning accuracy for automated assembly, packaging, and machining cells.

The motor’s electromagnetic output includes a continuous nominal thrust of 6,720 N and a peak capability of 21,500 N. A force constant of 226.9 N/A links commanded current to generated force, while the rated phase current is 29.6 A; transient moves can draw up to 143.1 A without demagnetization. An attractive force of 30,700 N must be considered when sizing mechanical guides. The winding set, identified by code 0060, presents 11.4 mH of inductance, 2.4 Ω of resistance at 20 °C, and a back-EMF constant of 130.9 Vs/m, which helps with compatible inverter selection. Motor size 300 indicates the active width, and the mover can reach 60 m/min at full force. Thermo-encapsulation stabilizes the coil pack, and wiring exits at the front of the housing for straightforward cabinet routing.

Thermal management relies on liquid cooling that removes 3,200 W of heat loss through an internal channel. A flow of 4.6 l/min keeps the stator below its limit, with a maximum inlet pressure of 10.0 bar and a pressure drop of 2.8 bar across the circuit. The system equalizes to operating temperature in only 2.4 minutes, helping maintain consistent force during rapid duty changes. Nominal travel speed is 110 m/min, and when motion feedback is required, an external scale or resolver must be supplied because no encoder is installed. The thermo-encapsulation method protects the windings from coolant ingress and vibration.
