The Bosch R911276042 (MDD093C-N-020-N2L-130PB2) is an AC servo motor offering a maximum speed of 2000 RPM. Cooling methods include natural convection and surface cooling, altering its performance specifics. When naturally convected, it possesses 19.5 Nm constant torque and 21.4 A sustained current at standstill, while surface cooling enhances these to 28 Nm torque and 30.8 A of current. It reaches a peak of 60.6 Nm torque and 96.5 A. Having a torque constant of 0.91 Nm/A, 0.56 Ohm motor winding resistance, and 6.1 mH winding inductance, the R911276042 (MDD093C-N-020-N2L-130PB2)'s thermal time constant is 50 minutes and 45 minutes with natural and surface cooling respectively. This 22 kg motor adopts digital servo feedback, has a DIN 6885-1 standard keyway, side B power connection, and a 22 Nm blocking brake. It’s ideal for high-density power applications like roller feeds due to its brushless, grease-lubricated bearing design. An integrated temperature sensor also wards off overtemperature conditions.
