MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-040-N2L-110GB0 from the MDD Synchronous Motors series is a high-performance motor for digital drive controllers optimized for precision motion control. Its plain shaft design and standard (without side B shaft end) configuration deliver a compact, service-friendly profile. Encased in a robust standard housing with integrated shaft seal, this motor offers reliable protection in demanding industrial environments. Supplied without a blocking brake, it remains highly versatile for applications requiring smooth deceleration.
Engineered to exacting standards, the MDD093D-N-040-N2L-110GB0 features a motor size of 093 matched to a centering diameter of 110 mm, ensuring precise alignment in tight assemblies. The unit provides a continuous torque at standstill of 24.0 Nm and sustains nominal speeds up to 4000 min⁻¹, driven by digital servo feedback (DSF) for high-resolution position tracking. A side B connection direction and sturdy connector interface simplify cabling, while standard balancing minimizes vibration at high speeds. The motor length code D optimizes rotor dynamics and thermal performance under continuous operation.
Seamless integration with Bosch Rexroth’s digital drive controllers streamlines commissioning and parameter tuning, reducing system complexity. The combination of robust sealing, standard balancing, and proven housing design ensures long-term reliability with minimal maintenance. Ideal for packaging machinery, material handling, and CNC applications, this motor delivers consistent performance and tight control in automated production lines.

Frequently Asked Questions
What happens to thermal management when operating near 4000 rpm continuous?
At high continuous speeds, heat generation in the rotor and stator increases; the motor’s thermal time constant and cooling method (convection, housing conduction) must be sufficient to avoid thermal saturation and torque drop. If cooling is inadequate, derating is required or additional cooling (e.g. forced-air or external cooling) becomes mandatory.
How critical is alignment when mounting to a machine spindle using the 110 mm centering diameter?
The tight centering diameter mandates precise fit and minimal radial play to avoid introducing shaft bending loads or vibrations at high speed. Poor alignment can lead to bearing stress, vibration, and compromised lifetime performance.
What considerations should be given to cable routing due to the side-B connection direction?
Side B connector placement means cable bundles must avoid tight bends or tension, and strain relief must be robust to prevent stress on the feedback and power connectors. Also, the motor housing and mounting should allow the cable exit path to be protected in harsh industrial environments.
What is the expected impact of standard balancing on vibration at high rpm?
“Standard balancing” helps reduce first-order dynamic imbalance, keeping vibration under control up to the rated speed, but for extreme precision or spindle-like applications, higher balance grades (e.g., R or S) may be required. Residual imbalance can excite resonances in the machine frame unless damping or structural stiffness is sufficient.
What are the maintenance implications of using a sealed housing with integrated shaft seal?
The shaft seal prevents contaminants and ingress from entering the motor, reducing wear and failure risk; however, it also means bearings must be lifetime-lubricated and non-serviceable in many cases. Motor servicing tends to require full replacement or factory repair rather than field lubrication or disassembly (a trait shared across the MDD family).
