R911251849
The Bosch Rexroth Indramat R911251849 (MDD112C-N-030-N2L-130PL1) is a technically advanced servo motor with specific mechanical specifications. With a frame size of 112 and frame length categorized as C, this motor boasts a centering diameter of 130mm. Measuring 462mm in length, it contains a shaft diameter of 32mm, a flange size of 193mm, and mounting hole diameters at 14mm. The motor adheres to DIN 42958 for its flange and allows B5 and B14 designs for mounting. The power connection takes place on the left side, although the power connector depending upon the motor needs to be separate. It is essential to note that the feedback connector shall also be separate. The motor operates most effectively at temperatures between 0 to 45 degrees Celsius and altitudes from 0 to 1000 meters.
For derated output, the working temperature ranges from 45 to 55 degrees Celsius and elevation from 1000 to 5000 meters. The R911251849 (MDD112C-N-030-N2L-130PL1) motor carries a shaft with a keyway and supports digital servo feedback for compatibility with a servo controller. The cooling process includes a natural connection or surface cooling, requiring a fan mounted radially or axially for the latter. With a nominal speed rating of 3000 RPM, the device has a standard blocking brake possessing 14 Nm holding torque to prevent unintended motor shaft rotation. The optional brakes for the MDD112C series servo motors have capacities of 40 Nm and 60 Nm.
