The Bosch Rexroth R911320932 (MSK071E-0450-FN-S2-UP0-RNNN) is an IndraDyn S synchronous servomotor featuring liquid cooling and a rotatable 240° encoder connector using the EnDat2.1 optical interface (2048 signal periods, singleturn). This motor has a shaft with keyway, no holding brake, and increased concentricity design. The unit supports a continuous current of 38 A, continuous torque of 43.7 Nm (liquid cooled), and maximum values of 90.1 A and 84.0 Nm, respectively. The operating voltage constant is 82.7 V/1000min-1, with a winding inductivity of 2,600 mH. The motor weighs 23.5 kg, is thermally rated at class 155 with a 19.8-minute thermal time constant, and allows operation from 0 to +40 °C at altitudes up to 1000 m. Sound pressure is rated below 75 dB. Proper installation and operation require technical expertise.
