Product Description:

The MDD112D-N-030-N2M-130PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into tightly regulated rotary motion for closed-loop positioning and speed control in industrial automation. The integrated multiturn absolute encoder provides immediate position information after power-up and supports coordinated motion on packaging machines, gantry stages, and material-handling units. Because feedback and motor response are coordinated through the drive system, the motor is well suited for axes that must follow short move profiles with repeatable settling behavior. This also supports synchronized operation where several machine axes must move together without losing position reference.

With a centering diameter of 130 mm, the motor registers precisely into mating flanges, and its power and feedback conductors exit on Side A through a connector interface that supports orderly cable routing. This cable orientation can make routing easier when the motor is mounted with its flange facing the driven mechanism. Position data are transmitted through digital servo feedback (DSF), which works with the encoder to support precise commutation and stable control behavior across the speed range. In continuous operation, the rotor can produce 38.0 Nm of standstill torque, while the winding supports a nominal speed of 3000 rpm under rated load. The combination of torque at zero speed and rated running speed suits servo applications that need both holding force during control and rapid movement between indexed positions. Standard dynamic balancing reduces vibration during acceleration, and the motor is supplied without an internal brake, which lowers rotating inertia.

The mechanical envelope uses frame size 112 with extended length code D, adding active stack height without changing the mounting pilot. A shaft seal protects the bearing area from contaminants, which helps when dust or light debris is present around the shaft opening. Torque is transferred through a keyway shaft, allowing positive coupling to pulleys, gears, or other driven elements that must resist slip. Because the unit is supplied without a blocking brake, axis holding must be provided by the drive or an external clamp. The standard housing uses a single-shaft layout with no side-B extension, which keeps the non-drive end unobstructed and leaves more room for surrounding machine components.
