Product Description:

Bosch Rexroth Indramat manufactured the MLP070B-0100-FS-N0CN-NNNN linear motor primary section. The unit belongs to the MLP Synchronous Linear Motors series and serves as the moving element in direct-drive axes that need controlled thrust along fixed tracks. By eliminating belts and gearboxes, it transfers electromagnetic force directly to gantries, pick-and-place modules, and high-speed transport stages in automated production lines.

The motor delivers a continuous nominal force of 820 N, a peak force of 2600 N, and an attractive pull of 3750 N. A force constant of 176.70 N/A links thrust to phase current, and the drive may supply up to 23.6 A for short-duty operation. Electrical characteristics include a voltage constant of 101.9 Vs/m, a winding inductance of 89.0 mH, and a winding resistance of 14.9 ohms. The primary section reaches 200 m/min nominally and can still attain 100 m/min under full load. Its thermal time constant is 2.4 minutes. The motor uses the 070 size code with length B, and the 37.5 mm pole width matches the companion rail. Leads exit at the front, which can simplify cable routing on compact moving axes, and no encoder is installed, so the axis must use external position feedback.

Heat generated in the windings is removed through liquid cooling, which requires a coolant flow of 1.3 l/min and causes a pressure drop of 0.3 bar at that minimum rate. This cooling method helps the assembly stay within temperature limits during high-duty cycles while maintaining stable force output. The standard encapsulation method seals the internal laminations against moisture and vibration. The moving mass is 10.4 kg, which helps keep inertia low for fast axis response. Liquid cooling also makes the motor well suited to repetitive motion profiles where sustained thrust would make passive cooling less practical.
