The Bosch Rexroth synchronous servomotor R911338990 (MSK101E-0300-NN-M2-AG3-RNNN) is designed for precision motion tasks, featuring a plain shaft, multiturn absolute optical EnDat2.1 encoder with 2048 signal periods, and natural convection cooling. It operates at a maximum speed of 4600 RPM and provides a maximum torque of 231 Nm. The winding inductivity is specified as 1.960 mH with a winding resistance of 0.11 ohms. The motor continuously delivers 70 Nm at 41.6 A and up to 80.5 Nm at 47.8 A when the winding temperature is at 100 K. A voltage constant of 113.8 V/1000 min⁻¹ and a torque constant of 1.85 Nm/A at 20°C are provided. The integrated electrically-released holding brake offers 120 Nm holding torque. The unit has a thermal time constant of 100 minutes, contains four pole pairs, and should be operated in environments between 0°C and +40°C, at a maximum altitude of 1000 meters. Power connection is provided on the A-side; motor design prioritizes increased concentricity.
