Product Description:

The MLP070A-0220-FS-N0CN-NQNN primary section is produced by Bosch Rexroth Indramat and belongs to the MLP Synchronous Linear Motors series. As a liquid-cooled synchronous linear motor, it generates thrust directly along the axis, which removes the need for belts, screws, or gear transmissions in many motion systems. The primary section works with a passive secondary track to convert controlled electrical current into linear force for pick-and-place modules, gantry axes, and machining centers. This arrangement supports precise positioning and repeatable travel speed in applications that require direct linear motion.

The unit delivers a continuous force of 550 N when coolant circulates through the stator, allowing steady operation without thermal overload. Its force constant is 90.70 N/A, so thrust rises in a predictable relationship with motor current. Rated phase current is 6.1 A, and short acceleration periods may draw up to 40.5 A. The cooling circuit requires 1.1 L/min through a 0.042 L duct and removes 780 W of heat. The winding has an inductance of 26.9 mH and a resistance of 4.7 ohms at 20 °C, which gives the motor electrical characteristics suited to standard IndraDrive amplifiers. The voltage constant is 52.3 Vs/m, the wires exit at the front, the housing uses the standard encapsulation method, and no encoder is installed.

The primary section can reach a peak force of 2000 N for brief intervals when higher thrust is required to overcome static friction or heavy process loads. During normal positioning duty, it reaches a nominal travel speed of 360 m/min, while operation at maximum permissible force limits speed to 220 m/min. The unit weighs 8.4 kg, corresponds to motor size 070, and uses length code A to fit narrow carriage layouts. An attractive force of 2900 N maintains magnetic coupling to the track. Thermal response is quick because the motor has a time constant of 2.4 min, so temperature changes follow load and coolant-flow changes without a long delay.
