The MSK101E synchronous motor by Bosch Rexroth, model R911338990 (MSK101E-0300-NN-M2-AG3-RNNN), is a top-tier leader in the engineering industry. It functions optimally with marked features like a maximum speed of 4600 RPM and a permissible sound pressure level under 75 dB. Equipped with an EnDat2.1 encoder (featuring absolute encoder characteristics), this model has a voltage constant of 113.8 V/1000 min-1 and winding inductivity of 1.960 mH. Promising a continuous torque of 70 Nm, it uses a stationary, continuous current of 41.6 A at 60 K. While the torque constant at 20 degrees Celsius is 1.85 Nm/A, the winding resistance is 0.11 ohms. The motor, with four polar pairs, has a thermal time constant of 100 minutes and a holding brake with a holding torque of 120 Nm. Careful handling is recommended to avoid damaging oscillations. Operating temperatures should range between 0 and +40 degrees Celsius, and the unit should be no more than 1000 meters above sea level.
