The Bosch Rexroth's MSK071E model R911390726 (MSK071E-0450-NN-M1-UP0-NNBN) is a durable synchronous motor with surface cooling compatibility and a thermal time constant of 19.8 minutes. It has a storage temperature range of -20 to +80 degrees Celsius. With a winding inductance of 2,600 mH and a resistance of 0.32 ohms, the motor operates optimally between 0 to 40 degrees Celsius with a relative humidity below 90%. At 20°C, its voltage constant stands at 82.7 V/min-1. The motor delivers a constant torque of 28 Nm at 100 K, drawing a current of 24.4 A. Featuring a Class 155 insulation and absolute hiperface encoder with multiple turns, the motor weighs just 23.5 kilograms and comes with a rotatable 240-degree plug. In rest condition with surface cooling, it provides 34.5 Nm of continuous torque using a 30 A of constant current, peaking to a max torque of 84 Nm at a top speed of 6000 rev/min under optimal conditions. Its IP65-rated housing provides protection from dust and water jets.
