The Bosch R911274266 (MDD090A-N-030-N2M-110GA2) is a MDD series servo motor, known for its feedback support through an integrated encoder sensor that gauges parameters like speed and torque. This information is relayed to the servo drive controller via a dedicated feedback cable, while the motor power, supplied by the controller, is connected through a separate power cable. The motor operates through natural convection or surface cooling, with the former allowing continuous torque and current at standstill at 3.7 Nm and 6.3 Amps, and the latter 5 Nm and 8.5 Amps. The motor features a plain output shaft, a housing with a 110mm centering diameter, and runs at a nominal speed of 3000 RPM. The thermal time constant is 45 minutes for natural convection and 30 minutes for surface cooling. Included is a blocking brake, which releases the motor shaft on application of a 24V DC signal.
