R911269104
The product at hand originates from the Bosch Rexroth Indramat's MDD series, known as the R911269104 (MDD112D-N-040-N2L-130PB2) AC servo motor. These motors, when paired with smart digital drive controllers from Bosch Rexroth, facilitate rapid, cost-effective automation systems. They align perfectly with applications in tooling, textiles, printing and packaging machines, robotics, handling and transfer equipment. The particular model R911269104 (MDD112D-N-040-N2L-130PB2) is highly beneficial in applications like grinding machines where extreme synchronism is crucial. The motor's rated speed is 4000 RPM and it comes encased in a standard design suitable for surface cooling and natural convection. Equipped with digital servo feedback, the main shaft contains a DIN 6885-1 keyway for optimal torque transfer and prevention of relative rotation.
The R911269104 (MDD112D-N-040-N2L-130PB2) motor features a 40 Nm rated holding-torque brake among three options of 14 Nm, 40 Nm, and 60 Nm. It responds to a 24 Volts DC signal releasing the shaft, drawing 1.35 Amps nominal current. The release delay is 150 milliseconds with a clamping delay of 30 milliseconds. Considering the motor weight of 59 kilograms and the brake weight of 3.5 kilograms, the total package weighs about 62.5 kilograms. It also features a power socket on side B with an insulation class of F and IP65 protection category. Ideal operational conditions include 0 to 45 degrees Celsius ambient temperature and 0 to 1000 meters altitude. Handling of the motor should be done by trained personnel.
