Product Description:

The MDD112D-N-040-N2M-130GA1 is a synchronous AC motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with compatible digital drive controllers and supplies tightly regulated torque and velocity to precision axes in automated assembly stations, material-handling gantries, and light machining spindles. By combining a permanent-magnet rotor with direct encoder feedback, the motor provides closed-loop motion control while supporting quick acceleration and repeatable positioning on production lines.

At installation, the centering pilot measures 130 mm, allowing rigid seating against machined register surfaces. Cables exit on side A, and the power and feedback conductors are combined in a single industrial connector, which helps keep cable routing orderly. Continuous torque at standstill is rated at 38.0 Nm, so the shaft can hold static loads without excessive heating. Rotor balancing follows the standard grade to limit residual vibration during operation. Position data are delivered by an integrated multi-turn absolute encoder, which reports absolute shaft angle over multiple revolutions and removes the need for homing. The housing is the standard unventilated version, and the mechanical dimensions follow motor length code D and size 112.

For power-off safety, a blocking brake is included, and it delivers 14.0 Nm of holding torque to secure vertical or suspended loads. Under command, the rotor reaches a nominal speed of 4000 rpm, supporting high-cycle applications that require short indexing times. Speed and position signals are transmitted as Digital servo feedback (DSF), enabling the drive to close a high-bandwidth control loop without external encoders. A shaft seal is fitted to restrict fluid ingress, and the standard shaft end is supplied as a plain shaft without a secondary extension, simplifying coupler selection.
