The Bosch Rexroth synchronous motor R911377391 (MSK100D-0300-NN-M2-BP2-RNNN) is an IndraDyn S series servomotor featuring a size 100 and length D configuration. It operates with natural convection cooling and integrates a multiturn absolute optical EnDat2.1 encoder with 2048 signal periods for position feedback. The motor shaft includes a keyway for torque transmission, and a 70 Nm electrically-released holding brake is present. Key electrical specifications include 0.35 ohm winding resistance, 5,650 mH inductance, a continuous current of 24.8 A at standstill (100 K), and a maximum current of 93.2 A. Performance ratings indicate up to 187 Nm maximum torque, 72 Nm continuous torque, and operation up to 3000 RPM. The rotor utilizes permanent magnets for low inertia, and a temperature sensor is integrated for thermal monitoring. The enclosure meets IP65 standards, specifying resistance to dust and liquid ingress. The power connector is located on the B-side, and the unit should be operated between 0 and +40 °C. This model is not available with motor length A.
