The Bosch Rexroth Indramat MDD093B-N-020-N2L-110PR1 from the MDD Synchronous Motors series delivers precision performance with a motor size of 093 and a motor length code B. This Indramat digital AC servo motor features digital servo feedback (DSF) for accurate rotor position and speed control, supporting a nominal speed of 2000 min⁻¹. The robust housing standard and shaft seal with shaft seal ensure reliable protection in diverse industrial environments. Designed as a motor for digital drive controllers, it integrates seamlessly with Rexroth drive systems.



Within its compact form, the MDD093B offers a continuous torque at standstill of 14.5 Nm and incorporates a blocking brake with holding brake torque of 11 Nm for secure holds under power-off conditions. The precision-balanced rotor (balancing standard) and 110 mm centering diameter guarantee low vibration and consistent alignment when mounted. The shaft type keyway per DIN 6885 sh. 1, 8-68 Edition simplifies coupling, and the standard shaft end without side B shaft end maintains compatibility across MDD series frames.



Connection is straightforward via the connector connection type oriented to the right connection direction, reducing installation time and wiring errors. Built on the legacy of Rexroth, Bosch, and Indramat quality, this servo motor excels in dynamic response, continuous duty, and modular integration, making it ideal for high-precision automation tasks.

Where is a 2000 rpm, ~14.5 Nm servo with a holding brake typically applied?

Common uses include packaging indexers, CNC feed axes, printing/labeling stations, textile machinery, robotics, and transfer lines—especially where the axis must hold position safely on power-off. Verify vertical-axis loads against brake and gearbox ratings.

How does digital servo feedback (DSF) simplify commissioning?

DSF carries motor parameters in the feedback memory, so the Rexroth drive auto-identifies the motor and sets safe defaults, reducing tuning time and commutation errors. It also provides precise position/speed data for tight control loops.

What’s the correct use of the 11 Nm holding (blocking) brake?

It’s a holding device, not a service brake—engage after the axis is nearly stopped; repeated dynamic stops will wear it (~20,000 revs against a closed brake). Use drive/dynamic braking or a mechanical brake for deceleration.

How do the 110 mm centering diameter and balanced rotor affect performance?

The centering pilot helps achieve concentric, repeatable mounting; the standard balancing minimizes vibration, improving tracking accuracy and bearing life at speed. Precision mounting reduces re-alignment time after service.

Any wiring and EMC considerations for longer cable runs?

Follow Rexroth guidance on maximum motor-power cable lengths (e.g., ~75 m on DDC/DDS systems) and use shielded cables to meet EMI limits. Separate power and feedback runs and ground per the drive manual.
