Product Description:

The MDD112C-N-040-N2M-130PB3 is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat and placed in the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides precise rotary motion for packaging lines, gantries, and machine tools that rely on closed-loop position and velocity control. The combination of internal feedback devices and a sealed housing allows the motor to integrate directly into industrial automation axes without separate sensors or additional protective covers. This arrangement supports compact machine layouts where feedback, torque production, and environmental protection must be combined in one motor assembly.

At the mechanical interface, the motor centers on a 130 mm pilot, and its rotor is balanced to a standard grade to help reduce vibration when coupled through the key-fitted shaft. Rated operation reaches a nominal speed of 4000 rpm, while a continuous standstill torque of 28.0 Nm supports static load holding during low-speed positioning. Power and feedback conductors exit on side B and are routed through a sealed connector, which helps keep cable routing compact at the rear of the motor. Motion data is returned to the drive through Digital servo feedback (DSF), allowing the controller to monitor rotor position and speed with high resolution. The motor uses size 112 with length code C, and the standard housing includes a shaft seal to help resist oil ingress at the output end.

For power-off holding, the unit is equipped with a blocking brake that supplies 60.0 Nm of holding torque, preventing unwanted shaft rotation while the machine is idle or stopped. Position retention over extended downtime is supported by an integrated multi-turn absolute encoder, which preserves rotational reference across several revolutions without requiring an external battery. The output shaft is machined with a keyway for positive torque transmission to the driven element. Because the motor does not have a second shaft end, couplings and other driven components are mounted only on the drive side, which leaves the opposite end closed and simplifies guarding around the rear section.
