The Bosch Rexroth R911335514 (MSK075E-0300-NN-S2-UG2-RNNN) is an IndraDyn S synchronous servo motor featuring a frame size of 075, length E, and winding code 0300. It delivers 21 Nm continuous torque at 14.2 A (60K) and 23 Nm at 15.6 A (100K) with natural convection, and up to 31.5 Nm torque and 21.3 A current with surface cooling. Peak torque reaches 88 Nm at 63.9 A. The motor utilizes a plain shaft, includes an electrically-released 30 Nm holding brake, and is equipped with an optical singleturn encoder (EnDat2.1, 2048 periods, 240° rotatable connector). Other parameters include a torque constant of 1.63 Nm/A, voltage constant of 1000 V/1000 RPM, winding resistance of 0.65 Ω, inductance of 4.46 mH, thermal time constant of 29 min, maximum speed of 5200 RPM, and a weight of 24.1 kg. The concentricity is enhanced by design and the motor includes four pole pairs.
