MDD093D-N-040-N2L-130GA2
MDD Synchronous Motors
The MDD093D-N-040-N2L-130GA2, Bosch Rexroth Indramat, MDD Synchronous Motors delivers precise motion in a compact, rugged package. Rated for a Nominal Speed of 4000 min⁻¹, it provides a Continuous Torque at Standstill of 24.0 Nm and engages a robust Holding Brake with a Holding Brake Torque of 22 Nm. Its Balancing is set to Standard for smooth running at high speeds, and it features a Plain shaft with Shaft Seal to protect against contaminants. The motor’s Housing follows the Standard design, ensuring compatibility with existing mounts and enclosures.
Boasting a Motor Size 093 and Centering Diameter of 130 mm, this motor integrates seamlessly into automated equipment. The Motor Length Code D keeps overall package dimensions minimal while preserving power density. It employs Digital servo feedback (DSF) for high-resolution position and speed control, transmitted via a Connector on Side A for straightforward wiring. Engineered as a Motor for digital drive controllers, it avoids extraneous side-B shaft ends, maintaining a clean footprint and simplifying coupling to gearboxes or encoders.
Designed for full integration into Bosch Rexroth Indramat drive systems, this motor ensures deterministic response and fault diagnostics via its digital feedback interface. Its blocking brake combines safety and reliability, holding loads securely during power interruptions and emergency stops. Ideal for packaging, printing, and indexing applications, the MDD093D-N-040-N2L-130GA2 excels in environments demanding precise synchronization and minimal downtime.

Frequently Asked Questions
How should the holding brake (22 Nm) be used in a machine design?
Use the brake to lock the shaft during power-off or emergency stops, but avoid relying on it for frequent dynamic braking because the brake is rated only for standby holding—not continuous cyclic operation. In high duty-cycle systems, supplement with dynamic braking or regenerative drive functions.
What installation constraints arise from the motor’s “plain shaft with shaft seal” design?
The sealed shaft protects against dust and spray, but you must avoid imposing excessive radial or axial loads on the seal area or misalignment that can degrade the seal over time. Also ensure coupling or gearing arrangements don’t torque the shaft in a way that bypasses or overloads the seal.
How does the motor’s standard balancing affect performance at 4000 min⁻¹?
“Standard” dynamic balancing ensures vibration is suppressed adequately up to typical operating speeds, but if your application is extremely sensitive (e.g. spindle-level precision) you might need a “reduced” or higher balance class. Excess imbalance at high speed would manifest as additional bearing loads, torque ripple, or noise.
What are the wiring and connector considerations for the digital servo feedback (DSF) interface?
The feedback connector must be oriented and wired correctly (pin assignment, shielding, twisting) and maintains signal integrity especially at high speeds and under EMI conditions. Choose low-noise, twisted pairs and follow the manufacturer’s guidelines to avoid position errors or communications faults.
How can one use the built-in feedback memory to simplify field reinstallation?
The DSF feedback stores motor parameters internally, so when reconnected the drive can auto-retrieve alignment/parameter data, reducing setup time and risk of misconfiguration. This also helps avoid manual entry of motor constants after a service swap.
