The Bosch Rexroth Indramat R911313947 (MSK071E-0300-NN-M1-UP1-NNNN) is an IndraDyn S synchronous servomotor featuring a 4-pole, size 071E design and natural convection cooling. The shaft incorporates a DIN6885-1 keyway and is equipped with an electrically released holding brake (23 Nm torque). The encoder utilizes optical technology, is multiturn absolute type with 128 signal periods, and supports a rotatable (240°) Hiperface interface. The motor is rated for continuous current at standstill 100 K of 15.2 A and continuous torque at standstill 100 K of 28.0 Nm. Peak values include a maximum current of 56.3 A and maximum torque of 84.0 Nm. Winding resistance is 0.79 Ohm at 20°C, winding inductivity is 5,900 mH, and the voltage constant is 126.4 V/min. The motor moment of inertia is 0.00290 kg·m² (without brakes). It is rated for axial and radial peak shock loads of 10 m/s² and 300 m/s², with vibration loads up to 10 m/s² axial and 30 m/s² radial. The thermal time constant is 19.8 minutes, the ambient operating temperature extends to 40°C, and the enclosure is rated IP65.
