Product Description:

The MLP070B-0100-FT-N0CN-NNNN is a synchronous linear motor module produced by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. It converts electrical current directly into linear thrust to move gantries, indexing conveyors, or pick-and-place axes without ballscrews or gearboxes. Size code 070 and length code B indicate a compact mover suited to medium payload ranges in automated assembly lines.

During continuous duty, the mover produces 820 N of thrust when energized at its rated 4.6 A. The relationship between current and force is given by a force constant of 176.70 N/A, permitting straightforward thrust control by the drive amplifier. For short acceleration bursts, the winding accepts 23.6 A, enabling a peak mechanical output of 2600 N while remaining below the 3750 N attractive force acting toward the magnet rail. Because back EMF rises with speed according to a voltage constant of 101.9 Vs/m, the controller must maintain adequate bus voltage to reach the nominal velocity of 200 m/min or the 100 m/min attainable at full load. These ratings support high-cycle positioning tasks in packaging and electronic assembly cells.

Thermal management is handled by liquid cooling; a stainless internal channel holds 0.082 L of coolant that circulates at 1.3 L/min to extract the 900 W of winding losses. This flow keeps temperature within the short thermal time constant of 2.4 min. The three-phase coil has an inductance of 89.0 mH and a resistance of 14.9 ohms at 20 °C, and these values affect current ripple and drive bandwidth. A thermo-encapsulation method seals the winding against vibration, and the 13.4 kg mass provides mechanical stiffness. Service cables are routed through the front face to simplify drag-chain layouts, and because no encoder is installed, an external scale or linear encoder must supply position feedback.
