The Bosch Rexroth MPN R911369951 (MSK050B-0300-NN-M1-BG1-NNNN) is an IndraDyn S Synchronous Servomotor designed for precision motion control in industrial automation systems. This unit features a plain shaft, size 050 and length B, with natural convection cooling and a B-side power connector. The synchronous motor delivers a continuous torque of 3.4 Nm and continuous current of 2.0 A at standstill (100 K), reaching a maximum speed of 4300 rpm and maximum torque of 9.0 Nm at a peak current of 7.2 A. The winding code is 0300, with an inductance of 76.4 mH. The integrated multiturn absolute optical encoder (Hiperface, 128 signal periods resolution) allows for precise position and speed feedback. The holding brake, electrically released, provides 6 Nm torque. The motor has 4 pole pairs, a discharge capacity of 2.1 nF, and an 8-minute thermal time constant.
