Product Description:

Bosch Rexroth Indramat produces the MDD112C-N-020-N2M-130GB0 as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into controlled rotary motion for servo axes in automated equipment. The design follows the 112 size designation and the C length code, offering a mid-range footprint that can be integrated into machine frames without special mounting adaptations.

At standstill, the motor can deliver a continuous torque of 28.0 Nm, allowing the axis to support loads or perform low-speed positioning without thermal overload. When energized by its inverter, the rotor reaches a nominal velocity of 2000 rpm, providing a predictable speed reference for control loops. Accurate mechanical alignment during installation is assisted by the 130 mm centering diameter machined into the front flange. Power, brake, and feedback leads exit on side B of the housing through a plug-in connector, which simplifies cable routing in tight control cabinets. The output is a plain shaft with no keyway, so couplings or belt pulleys seat directly on the journal and torsional backlash is minimized in servo applications.

Closed-loop operation relies on digital servo feedback (DSF) produced by the integrated multi-turn absolute encoder, so the controller always knows the rotor position across multiple revolutions. The unit is supplied without a blocking brake, reducing inertial mass where static mechanical holding force is unnecessary. A shaft seal is fitted at the output end to resist coolant splash and fine dust that might otherwise enter the bearing chamber. Standard dynamic balancing keeps vibration low during acceleration, and the standard housing style lets the motor match existing MDD mounting hardware in general-purpose synchronous drive installations.
