Product Description:

The MDD112C-N-020-N2L-130GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts drive output current into controlled rotary motion so automated axes can follow position and velocity commands without mechanical overshoot. This capability allows direct coupling to gearboxes, ball screws, or belt transmissions wherever precise speed regulation and closed-loop positioning are required on packaging lines, printing presses, or material-handling gantries.

The motor can deliver a continuous standstill torque of 28.0 Nm. This indicates how much static load the shaft can hold without overheating while the rotor remains locked in position. Its nominal speed is 2000 rpm, which is the reference rotational velocity under rated voltage and load and helps determine transmission ratios and cycle times. A centering diameter of 130 mm provides the locating surface that aligns the housing concentrically on a mounting flange. Power and feedback cables exit at the rear because the connection hardware is oriented toward side B, which is useful where wiring must avoid neighboring mechanics. Commutation and position data are returned through digital servo feedback, enabling the controller to adjust current vectors with high resolution during acceleration or regenerative braking.

For emergency stops or vertical-axis holding, the integrated blocking brake supplies 14.0 Nm of static torque once its coil is de-energized. The single-ended rotor has a plain shaft, allowing couplings or pulleys to be fitted without a keyway. Contaminant ingress at the output is limited by a shaft seal, so lubrication stays inside and coolant spray stays outside. With a frame code of 112, the motor occupies a medium-power position in the series, and its standard dynamic balancing keeps vibration within limits as the drivetrain moves through speed profiles.
