MDD090C-N-030-N5L-110GB0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090C-N-030-N5L-110GB0 is a powerful member of the MDD Synchronous Motors series, designed to provide reliable motion control in industrial automation. Featuring a Continuous Torque at Standstill of 10.4 Nm and a Nominal Speed of 3000 min⁻¹, this motor delivers smooth and precise positioning under varying load conditions. Built to the IP 65 protection category, the device resists dust and low-pressure water jets, ensuring consistent performance in harsh manufacturing environments.
This servo motor is engineered with advanced technical specifications to meet demanding operational requirements. It has a compact Motor Size of 090 and achieves a Torque Constant at 20 °C of 0.53 Nm/A, converting electrical input to mechanical torque with high efficiency. The Thermal Time Constant of 60 min (45 min with surface cooling) optimizes heat dissipation, while the Windings Resistance at 20 °C of 0.46 Ω and a Maximum Current of 117.8 A support high power density. Digital servo feedback (DSF) enhances control accuracy, and the integrated Shaft Seal ensures long-term reliability by preventing contamination.
Beyond core performance, the MDD090C-N-030-N5L-110GB0 offers additional features that reinforce its suitability for industrial drives. The Connection Direction: Side B simplifies cabinet layouts, and the Centering Diameter of 110 mm enables precise alignment. Standard balancing and a design without a blocking brake reduce noise and vibration. The motor’s materials and construction meet a Permissible Storage Temperature range of -20 to +80 °C, supporting global deployment. As a digitally compatible motor for drive controllers, it delivers exceptional efficiency and durability in automated production lines, improving throughput and minimizing downtime.

Frequently Asked Questions
Why is a centering diameter of 110 mm significant for this motor?
The 110 mm centering diameter ensures compatibility with standardized framings and bearings, simplifying integration into machine tool or packaging assemblies. It also contributes to stable mounting and minimal mechanical run-out.
What is the benefit of the motor’s winding resistance of 0.46 Ω at 20 °C in this motor?
The lower winding resistance of MDD090C-N-030-N5L-110GB0 motor reduces I²R losses, improving electrical efficiency and limiting heat generation. This allows the motor to deliver its 10.4 Nm torque with lower thermal stress and better sustainability.
How does the rotor inertia of 53 × 10⁻⁴ kg·m² help in the MDD090C-N-030-N5L-110GB0 motor’s dynamic response?
A relatively low rotor inertia allows the motor to accelerate and decelerate rapidly, improving cycle times in automation. This is beneficial in the MDD090C-N-030-N5L-110GB0 motor for applications like pick-and-place or high-speed indexing.
What advantage does the inductance value of 2.6 mH provide in this motor?
The 2.6 mH inductance smooths current transitions and mitigates current spikes during changes in torque demand. This contributes to stable servo performance and protects the drive electronics.
Why is IP65 protection (excluding output shaft) important for the MDD090C-N-030-N5L-110GB0 motor?
The IP65 ensures the motor is highly resistant to dust ingress and water jets, making it suitable for industrial floors or packaging lines. For this motor, it enhances reliability and reduces maintenance in harsh environments.
