Product Description:

The Bosch Rexroth Indramat MLP070B-0120-FT-N0CN-NNNN is a primary section in the MLP Synchronous Linear Motors series, built to generate direct linear thrust for automated gantries, pick-and-place axes, and machine-tool slides. Size code 070 uses a 37.5 mm pole width, and length code B identifies a mid-length active track. The 13.4 kg mover routes its power leads through the front of the housing, which helps support compact cable routing on moving axes. Its windings are secured by a thermo-encapsulation method that withstands vibration during repeated motion. Because no encoder is installed, external feedback devices must provide position reporting.

Under continuous duty, the carrier produces 820 N of thrust while drawing 5.9 A. At that load, the coils dissipate 900 W that must be removed by the coolant loop. The phase circuit has a resistance of 9.2 Ω at 20 °C and an inductance of 55.3 mH, and these values affect current ripple and controller tuning. A thermal time constant of 2.4 min shows how quickly the winding temperature follows changing load, allowing brief overloads within the thermal response of the motor. Even with zero travel command, the magnetic field produces 3 750 N of attractive force toward the reaction plate, so the mounting structure must withstand that static pull.

Peak moves can reach a force of 2 600 N by supplying up to 42.8 A per phase. When operated at that limit, the slide tops out at 120 m/min, whereas normal operation permits a travel speed of 220 m/min. Heat is extracted through closed-loop Liquid Cooling, and the circuit must provide at least 1.3 l/min of flow while staying below 10 bar inlet pressure to avoid hose damage. The motor is intended for use with the matching reaction rail in the MLP product group, and stable coolant flow helps maintain consistent thrust during high-load travel.
