Product Description:

The MLP070B-0250-FT-N0CN-NNNN linear motor primary section is produced by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. This unit supplies direct thrust along a flat track, removing belts or screws from the drive train and improving position accuracy in packaging, assembly, and printing machinery. Because the stator creates force without rotary conversion, it helps reduce backlash, mechanical wear, and routine maintenance in high-speed automated equipment. It works with a compatible secondary track to generate motion directly along the axis.

Under continuous duty, the motor generates 820 N of thrust while coolant circulates through internal passages. A force constant of 79.10 N/A lets the drive controller translate commanded current into predictable linear force. The rated current is 10.4 A, and that operating limit is associated with a winding resistance of 3.0 Ω and an inductance of 17.0 mH, which influence current rise in the servo loop. Back EMF follows a voltage constant of 45.6 Vs/m. Power conductors are routed through the front face, and the coil pack is sealed by a thermo-encapsulation method that helps support vibration stability. Winding code 0250 corresponds to these electrical characteristics, and the size 070 housing uses length code B to match standard secondary tracks.

For peak moves, the primary part withstands an attractive normal load of 3750 N toward the magnetic track and can reach 2600 N of thrust when the drive supplies up to 57.1 A. Nominal travel speed is 400 m/min, yet the assembly still reaches 250 m/min at maximum force. Heat is controlled by Liquid Cooling; the circuit accepts water-glycol coolant at inlet pressures up to 10.0 bar and limits surface temperature rise to 2 K, with a thermal time constant of 2.4 minutes. The module weighs 13.4 kg and is supplied without an encoder, so position feedback must come from a separate measuring system on the axis.
