Product Description:

The MDD112D-N-020-N2L-130PA3 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts electrical commands into rotary motion for automated gantries, presses, and indexing tables. Its integrated feedback system sends position and velocity data back to the drive in real time so the control loop can apply corrective current and maintain commanded trajectories under variable load. This arrangement supports closed-loop axes that must repeat position accurately during acceleration, dwell, and reversing moves.

At standstill, the rotor can deliver 38.0 Nm of continuous torque. This continuous torque supports holding force or low-speed motion without overheating. During regular operation, it reaches a nominal speed of 2000 rpm, so the motor is suited to applications that require stable speed over a broad operating range. A blocking brake mounted on the B-side supplies up to 60.0 Nm of static restraint to hold the axis when power is removed. Position recognition relies on digital servo feedback (DSF), allowing high-resolution monitoring with low phase lag. Mechanical centering is simplified by a 130 mm pilot diameter that seats the motor concentrically in the machine frame, and all power and feedback leads exit on Side A to keep cable routing orderly.

Standard dynamic balancing limits residual vibration, and the cast-aluminum housing helps shield the stator windings from dust and fluid splash. Wiring is completed through a keyed connector that mates with compatible family cables and helps prevent incorrect orientation during installation. Length code D gives the motor a longer housing than shorter versions, while frame size 112 fits couplings used in this torque class. A shaft seal helps block spray ingress, and the single-ended shaft uses a keyway for positive torque transfer. The motor has no side-B shaft extension, which leaves more clearance at that end of the machine layout.
