Product Description:
The MDD112D-N-030-N2M-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it delivers controlled rotation to position and velocity loops in automated packaging, printing, and assembly equipment. The motor is intended for machine axes that require accurate response during starting, stopping, and speed changes. A blocking brake is installed so loads can be mechanically secured whenever the drive is de-energized, which helps prevent drift on vertically loaded axes.
A centering flange diameter of 130 mm aligns the housing with machine frames, and standard balancing helps limit residual vibration at operating speed. The electrical terminations exit on Side B, and a single connector simplifies cable routing. When energized, the motor can supply a continuous standstill torque of 38.0 Nm, enabling accurate static holding without additional cooling. During motion, it reaches a nominal speed of 3000 rpm, matching high-throughput axes that require quick indexing. The integrated brake counters up to 14.0 Nm of back-driving force so suspended loads remain secure. The size code 112 and length code D indicate the larger magnetic stack used for this frame, which supports the stated torque while keeping the housing within the standard series envelope.
Position data are returned through Digital servo feedback (DSF) generated by an integrated multiturn absolute encoder, allowing the controller to read speed and multi-turn position without an external sensor. That encoder preserves absolute position across multiple revolutions, so the drive can retain shaft location information after power interruption. A factory-installed shaft seal protects the bearings from lubricant washout and airborne contaminants, and the standard housing is suitable for indoor machinery. The shaft seal also helps keep debris away from the bearing area during regular production use. Power is transmitted through a shaft machined with a keyway, while the opposite end has no shaft extension on side B, leaving the motor in a standard single-shaft configuration.
