The Bosch Rexroth servomotor R911372183 (MSK101C-0450-NN-S1-BG0-NNNN) is an IndraDyn S synchronous motor with standard design, motor size 101, and a C-length configuration. It features a plain shaft and uses M23/M58 flanges for encoder and power interface, with a B-side power connector. The unit employs optical Hiperface singleturn encoder technology, providing 128 signal periods. Rated for natural convection cooling, it requires 100 mm clearance for proper airflow and is suitable for operation up to 55°C ambient temperature and 3000 m installation altitude. The winding code is 0450, delivering a continuous current at standstill of 28.6 A and a continuous torque at standstill of 36.5 Nm at 100 K. Maximum current and torque are 113.0 A and 110.0 Nm, respectively, with a winding inductivity of 3,300 mH. Maximum permissible radial shock load is 200 m/s² for 11 ms. The device has no holding brake and includes a temperature sensor that signals if housing temperature exceeds 140°C. Inspection of bearings and encoders is required after 12 months of storage. Ambient humidity during operation and storage ranges from 1 g/m³ to 29 g/m³. Failure to operate may result from voltage or controller faults. The construction permits quiet, backlash-free, force-fit shaft hub connection.
