MDD090A-N-020-N2L-130GB1
MDD Synchronous Motors
MDD090A-N-020-N2L-130GB1, Bosch Rexroth Indramat, MDD Synchronous Motors delivers precision torque in a modular design optimized for digital drive controllers. This Product Type is engineered as a high-performance motor for digital drive controllers, featuring a Motor Size of 090 and a compact Motor Length Code A profile. The motor’s plain shaft complements the standard Shaft End configuration, enabling straightforward mechanical integration. Designed for side-mounted connections, the unit employs a robust Connection Type via connector on the Connection Direction face.
In operation, the MDD090A-N-020-N2L-130GB1 maintains a Continuous Torque at Standstill of 3.7 Nm and a swift Nominal Speed of 2000 min⁻¹. A Holding Brake with a blocking brake function adds safety under load, generating a Holding Brake Torque of 6.5 Nm for secure stops. The motor’s 130 mm Centering Diameter and standard Housing ensure compatibility with existing mountings, while Balancing to standard specification reduces vibration at high speeds. Integrated Motor Feedback via Digital Servo Feedback (DSF) permits precise position control and closed-loop regulation. A Shaft Seal protects the internal bearings and electronics against contaminants, extending service intervals.
Engineered for seamless integration, this synchronous motor interfaces directly with Rexroth Indramat digital drives, streamlining commissioning. The combination of DSF feedback and a sealed shaft assembly enhances reliability in demanding industrial environments. Ideal for robotics, packaging, and CNC applications, the MDD090A-N-020-N2L-130GB1 delivers consistent performance and simplified maintenance across automated systems.

Frequently Asked Questions
What impact does the 21.9 A maximum current have on system performance?
The 21.9 A maximum current ensures the motor can handle high loads and demanding applications. However, it requires efficient power supply and thermal management to avoid overheating under prolonged operation.
How does the windings inductance of 27.7 mH affect motor responsiveness?
The 27.7 mH windings inductance introduces a delay in the motor’s response to rapid changes in current, which can affect system performance in high-speed or precision control applications.
What are the benefits of using the balancing class Standard (R per DIN VDE) in motor systems?
The balancing class Standard (R per DIN VDE) ensures smooth motor operation by minimizing vibrations, enhancing the motor's efficiency, and prolonging the lifespan of the motor and associated components.
How does the black prime coat (RAL 9005) improve the motor’s durability in outdoor environments?
The black prime coat (RAL 9005) protects the motor from UV rays, corrosion, and other environmental stressors, making it more suitable for use in outdoor or harsh industrial environments.
How does the housing design, suited for natural convection, affect the MDD090A-N-020-N2L-130GB1 motor’s cooling efficiency?
The natural convection design allows the motor to dissipate heat passively through the motor casing, which is energy-efficient but may not be sufficient in high-load applications, requiring forced cooling in those cases.
