MDD025A-N-100-N2G-040GB0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD025A-N-100-N2G-040GB0 is a precision-engineered member of the MDD Synchronous Motors series designed as a Motor for digital drive controllers. This Product Type features a compact Motor Size 025 frame with a Motor Length Code A configuration, ensuring a balanced footprint for high-density installations. Equipped with robust Resolver feedback for precise position sensing and control, the unit delivers consistent performance in demanding automation tasks. Its Plain shaft design simplifies coupling to a variety of machine interfaces while maintaining rigidity and alignment.
Engineered for smooth operation, the MDD025A-N-100-N2G-040GB0 offers a Continuous Torque at Standstill of 0.33 Nm and spins up to a Nominal Speed of 10000 min⁻¹ for rapid acceleration profiles. A Centering Diameter of 40 mm ensures accurate mounting on hollow or solid shaft hubs, complemented by a With shaft seal feature that guards against contaminants in harsh environments. The absence of a blocking brake (Without blocking brake) reduces mechanical complexity, while Standard housing and Standard balancing optimize thermal dissipation and vibration control. Connectivity is streamlined through a side-mounted Connector interface (Connection Direction: Side B), facilitating wiring and service access in tight cabinet layouts.
This motor for digital drive controllers integrates seamlessly with Bosch Rexroth’s range of IndraDrive systems, enabling fast commissioning and adaptive control strategies. Its combination of high-speed capability, resolver feedback accuracy, and robust shaft sealing makes it ideal for packaging machines, pick-and-place robotics, and other high-throughput applications. Backed by the reliability standards of the Indramat brand, the MDD025A-N-100-N2G-040GB0 ensures consistent uptime and precision motion control across industrial automation projects.

Frequently Asked Questions
How does resolver feedback in this motor affect closed-loop precision compared to encoder feedback?
Resolver feedback offers excellent robustness in harsh environments (e.g. electrical noise, vibration, temperature fluctuations) and provides continuous absolute position without needing homing; however, its resolution is generally lower than high-resolution optical encoders, so fine motion profiles may show slight quantization effects.
What are the trade-offs of a plain shaft design (no keyway) versus a keyed shaft in high-torque coupling for this kind of motor?
A plain shaft simplifies machining and alignment and avoids stress concentrations at key slots, but coupling must rely on clamping or shrink-fit type hubs; under high torque or shock loads, a keyed shaft can offer more secure torque transmission but introduces potential fatigue points.
How important is the centering diameter (40 mm) for mounting accuracy and what tolerances should be expected when integrating into a machine?
The 40 mm centering diameter ensures the motor can be precisely located using standard hubs or hollow shaft mounts; mounting tolerances should be within a few hundred micrometers radially and angular misalignment minimized to avoid vibration, seal wear, or premature bearing failure.
What is the effect of having a shaft seal (“with shaft seal”) in this motor for environments with dust, moisture or contaminants?
The shaft seal helps protect interior components (bearings, windings) from ingress of dust, moisture, or particles, thereby improving reliability in harsher environments; but seals introduce friction and might limit maximum permissible shaft speed slightly, and require correct installation to avoid leakage or seal failure.
In a pick-and-place robotic application, how does the continuous torque at standstill of 0.33 Nm impact holding performance and servo tuning?
Having 0.33 Nm holding torque means the motor can resist small external loads or gravity when stopped without drift, but larger holding loads will need mechanical brakes or gearing; servo tuning must account for the torque-to-inertia ratio to avoid overshoot or instability during sudden starts/stops.
