Product Description:

The MDD112B-N-030-N2M-180PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it provides closed-loop rotary power to axes that require accurate speed and torque control in automated machinery. Its housing follows the standard proportions used in this motor line, which helps it fit machine layouts already prepared for the same frame family. This makes the unit suitable for positioning tasks in equipment where repeatable motion and stable servo response are required during normal production cycles.

This model delivers a continuous standstill torque of 17.5 Nm, so it can maintain rated holding torque at zero speed without excessive heating under proper operating conditions. Its centering flange has a diameter of 180 mm, which supports direct alignment with driven machine components such as gear units or pulley arrangements. Power and feedback cables exit on side B, and the motor uses a plug-in connector interface for a compact electrical connection. At rated operation, the rotor reaches a nominal speed of 3000 rpm, which suits medium-inertia applications that require responsive indexing and smooth speed regulation. The shaft sealing arrangement helps protect internal bearings from coolant splash and fine debris during operation.

Position information is provided by an integrated multiturn absolute encoder, and the signals are transmitted as digital servo feedback (DSF) to the drive controller for real-time correction. The motor is supplied without a blocking brake, so load holding during power-off must be handled by external means when the application requires it. Torque is transmitted through a keyway shaft, while the opposite end remains closed because the motor does not use an additional rear shaft extension. The motor also uses frame size 112 with length code B, which places it within the standard mechanical envelope for this series and supports installation where that form factor is already specified.
