The MSK071D-0300-FN-S1-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In closed-loop drive systems it converts controlled current from IndraDrive amplifiers into precise shaft torque and speed, allowing coordinated motion on packaging lines, machine tools, and material-handling axes. Motor size 071 together with the D-length housing places the unit in the medium-frame segment, supplying continuous power without increasing cabinet depth.
Because of its Liquid cooling circuit, waste heat is extracted through a coolant jacket so the stator can sustain higher current density than an air-cooled equivalent. The frame follows the Standard mechanical design, so mounting faces and pilot diameters align with other motors in the series. Size code 071 fixes the flange pattern, while length code D accommodates winding code 0300, which defines the copper cross-section and resistance. The unit is shipped Without a holding brake; position retention during power loss must therefore be handled by the drive or an external lock. A plain shaft transmits torque directly to couplings, and the liquid circuit keeps steady temperatures at elevated duty cycles.
The feedback assembly is serviced through a Rotatable, 240° connector that simplifies cable routing in confined enclosures. Position data is generated by an Optical measuring system that delivers a resolution of 128 signal periods and communicates with the drive via the Hiperface interface. The encoder is a singleturn device, adequate for axes that reference an external homing switch once per cycle. Together, the cooling method, winding selection, and encoder package give the motor stable speed control across repetitive start-stop sequences while maintaining compact installation geometry.
