Product Description:

The MDD071B-N-030-N2T-095GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Geared toward digital drive controllers, the unit converts precisely regulated current into accurate rotary motion for indexing tables, pick-and-place axes, and light-duty spindles on automated lines. Its compact frame supports direct mounting in high-density machinery, allowing integration of a self-contained rotary axis without external gear stages or belt transmissions. This layout helps reduce drivetrain complexity and supports repeatable positioning during frequent starts, stops, and short indexing moves.

At a continuous standstill torque of 4.4 Nm, the motor can hold static loads or maintain low-speed feed movements without overheating. When commanded to its rated speed of 3000 rpm, the motor maintains smooth torque delivery, aided by standard dynamic balancing of the rotor assembly. A built-in brake applies 3.0 Nm of holding torque to secure vertical or suspended loads when power is removed. Mounting is centered by a 95 mm pilot diameter that aligns the flange with gearboxes or machine plates, while a front-face connector simplifies wiring. Position data are generated by an integrated multi-turn absolute encoder, eliminating the need for external homing routines. The B length code gives the stator a medium axial dimension, and the standard housing profile fits common enclosure cutouts.

The drive controller receives feedback through digital servo feedback, enabling high-resolution current loops without extra transducers. Mechanical power exits through a plain shaft, and the power and signal cables are routed on Side A of the housing. A shaft seal is fitted to limit lubricant loss and exclude contaminants. The motor is categorized as size 071, and the shaft is provided only on the drive end, leaving the opposite face free for tight mounting spaces.
