The R911251905 (MDD065D-N-060-N2L-095PB1) is a MDD series servo motor from Bosch Rexroth, encapsulated in an IP65 rated casing that protects against dust and waterjets, suitable for both natural convection and surface cooling applications. It operates at a nominal speed of 6000 RPM, with usable speeds determined by the torque requirements. Its performance specifications include a 30-minute thermal time constant, along with a continuous torque of 2.7 Nm and a continuous current of 10.3 Amps for natural convection cooling- for surface cooling, these values change to a 15-minute thermal constant, 3.5 Nm torque and 13.3 Amps current. The motor supports digital servo feedback, an output shaft with keyway, a power connection towards side B, and an optional blocking brake characterized by a 3 Nm holding torque, 24 Volts nominal voltage, 0.6 Amps current, 30 milliseconds release, and 15 milliseconds clamping delay. Handle and use only by trained personnel, with approved accessories and all safety instructions followed rigorously.
