The digitally controlled synchronous servo motor R911325541 (MSK071D-0300-NN-S2-UG1-RNNN) is designed for natural convection cooling and supports operation with surface cooling. It functions within 0–40°C ambient temperature and up to 1000 meters altitude. The motor provides a maximum torque of 66 Nm with a maximum current of 40.5 A. Continuous torque at standstill is 17.5 Nm at 60K and 20 Nm at 100K overtemperature, increasing to 26.3 Nm with surface cooling. It features a torque constant of 2.12 Nm/A, voltage constant of 134 V/1000 RPM, and rated speed of 3800 RPM. The shaft is plain, mass is 19.6 kg, and it incorporates a rotatable connector and singleturn optical EnDat2.1 encoder with 2048 signal periods resolution. The holding brake provides 23 Nm torque and is electrically released. Additional data includes a winding inductivity of 10,700 mH, a thermal time constant of 54 minutes, and leakage capacitance of 7.2 nF.
