The Bosch Rexroth R911325541 (MSK071D-0300-NN-S2-UG1-RNNN) is a digitally operated servo motor engineered for convection cooling. Designed for optimum performance in ambient temperatures from 0 to 40 degrees Celsius and elevations from 0 to 1000 meters, the motor can also function with surface cooling. With a maximum torque of 66Nm and a maximum current of 40.5A, the motor offers continuous torque at standstill of 17.5Nm for 60K and 20Nm for a 100K overtemperatures. These values increase to 26.3Nm and 13.5A when used with surface cooling. The motor's torque constant is 2.12 Nm/A with a voltage constant of 134 V/1000 RPM. Other important features include a thermal time constant of 54 minutes, rated speed of 3800 RPM, and a leakage capacitance of 7.2nF. The 19.6 kg device is equipped with a plain motor shaft, rotatable connectors, and is sealed for longevity. The product comes with an integrated optical singleturn encoder for enhanced precision.
