Product Description:

The MDD112D-N-020-N2M-130GA3 is a motor for digital drive controllers supplied within the MDD Synchronous Motors series. As a permanently excited AC servo unit, it provides closed-loop rotary motion for axes that require tightly synchronized positioning and stable velocity control in automated machinery and transfer lines. Its mechanical frame corresponds to motor size 112, and both the housing and balancing are standard for this motor class. This layout suits applications that need a consistent servo platform without special mechanical variations.

The front flange has a centering diameter of 130 mm for accurate alignment on precision mounting faces, while the power and feedback leads exit through a connector for a plug-in electrical connection. At standstill, the rotor can maintain 38.0 Nm of continuous torque. Its rated operating speed is 2000 rpm, allowing normal operation under nominal thermal conditions. Position information is supplied by an integrated multi-turn absolute encoder, allowing the controller to recover the absolute shaft position after a power interruption. The motor also uses length code D for an extended active stack, and it has a plain centric shaft end with no second shaft extension on side B. A shaft seal is fitted at the output to help prevent lubricant migration when the motor is mounted to a gearbox.

For static holding or emergency stops, the blocking brake provides 60.0 Nm of torque and is energized through the same conduit arranged on side A of the housing. Motion feedback reaches the drive through digital servo feedback (DSF), which matches controller families that process high-resolution serial feedback data. The rotor has a plain shaft intended for clamping or shrink-fit couplings. The shaft seal at the output also helps maintain IP65 protection at the interface. These features support medium-inertia positioning duties that require controlled braking and reliable feedback without adding separate holding hardware.
