The Bosch Rexroth R911278653 (MDD090C-N-040-N2M-110PB1) is a reliable AC servo motor, used widely in industrial machinery. This motor functions with a shaft that rotates in time with the applied current's frequency, using numerous multiphase AC electromagnets on its stator to power the rotor. With a moment of inertia at 53 x 10-4 kgm2, the model can reach a maximum rotation speed of 4,000 RPM. The motor's exterior has a black primer coating, which can be covered with additional paint that must not exceed 40 µm thickness. The R911278653 (MDD090C-N-040-N2M-110PB1) model also includes an electrically operated blocking brake with respective clamping and release delays of 60ms and 20ms. To meet emission limits in various usage environments, power supply channels should be entirely covered, using PG threaded joints to ground the motor power connector. The motor's operational current consumption peaks at 145A with a winding inductivity of 1.6 mH. It produces a continuous torque of 10.4Nm, drawing a cotinuous current of 24.4A, and weighs 23kg without attachments. The R911278653 (MDD090C-N-040-N2M-110PB1) comes with a one-year replacement warranty.
