Product Description:

The MLP200C-0090-FS-N0CN-NNNN linear motor primary section is produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. It uses motor size 200 and winding code 0090, which identifies the coil arrangement used for this length. The unit has standard encapsulation, and its three-phase wiring is routed through the front face to simplify cable routing inside a machine frame. Liquid-cooling channels run through the stack, and because no encoder is installed, the axis uses an external feedback strip matched to the selected automation controller.

Under continuous duty, the mover produces a linear thrust of 4,460 N at a rated phase current of 22.9 A. With a force constant of 194.10 N/A, the drive converts each ampere from the inverter into nearly two hundred newtons of force, which supports tight force control during machining passes. Electrical behavior is influenced by a winding inductance of 13.6 mH and a DC resistance of 2.64 Ω, and these values affect current rise time and copper losses. Its voltage constant is 112.5 Vs/m, which the controller uses when estimating back EMF. The thermal time constant is 2.4 min, which helps limit temperature overshoot, while the coolant circuit must remove 2,700 W of power loss. For short bursts, the mover can accept up to 117.9 A without demagnetization.

In peak operation, the actuator delivers a maximum force of 14,250 N and must resist an attractive magnetic load of 20,500 N between the primary and secondary tracks. To support this condition, the liquid-cooling loop requires 3.9 L/min of flow and produces only 2.0 bar of pressure loss at the minimum rate. Full force is available up to 90 m/min, while unloaded travel reaches 170 m/min. A pole width of 37.5 mm sets the magnetic pitch and matches the track profile used in the MLP system.
