The R911398121 (MSK101E-0300-NN-M1-RG3-NNNN) is a synchronous servomotor from Bosch Rexroth designed for demanding automation applications, such as metal machining, woodworking, paper manufacturing, metal forming, and food processing. It features natural convection cooling, a right-side power connector, and a plain shaft. The integrated Hiperface optical multiturn absolute encoder provides 128 signal periods per revolution for precise position feedback. This motor supports a maximum speed of 4600 rpm, delivers a constant torque of 70 Nm at a 60K overtemperature, and achieves up to 231 Nm peak torque with a maximum current of 187.4 A. The holding brake is electrically released and rated for 120 Nm. Additional specifications include a motor size of 101, length E, winding code 0300, continuous current at standstill (100 K) of 47.8 A, continuous torque at standstill (100 K) of 80.5 Nm, and winding inductivity of 1,960 mH. Overpressure sealing enables operation in humid environments by maintaining internal overpressure.
