Bosch Rexroth's R911257979 (MDD093A-N-040-N2L-110GB2) model, a globally recognized AC servo motor, is renowned for its high-grade performance and efficiency. Boasting a class N balance and 2.8 mH winding inductance, this unit operates optimally when combined with a drive controller. Its notable features include a consistent 9.2 Nm torque output and 23.3 A current when idle. It showcases a winding resistance and torque constant of 0.36 ohms and 0.39 Nm/A respectively at 20°C while a sealing ring protects its plain output shaft against lubricants. The unit excels in precision contouring, operating at maximum speeds of 4000 rpm with a peak output torque of 28.6 Nm. Their quick thermal time constant of 50 minutes, coolable housing, and digital servo feedback enhance performance monitoring. This IP65 certified, 13-kilogram model includes a B-side power connection with a holding brake weighing 1.1 kilograms. Furthermore, it operates at a peak current of 104.8 A and demonstrates an inertia moment of 22 x 10-4 kgm2.
