MDD090A-N-020-N2L-130PL0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090A-N-020-N2L-130PL0 is a high-performance member of the MDD Synchronous Motors family, precisely engineered for advanced automation tasks. This digital AC servo motor from Bosch Rexroth Indramat features a compact Motor Length Code A housing and a substantial Centering Diameter of 130 mm to ensure robust mechanical alignment. The unit’s Nominal Speed of 2000 min⁻¹ and Continuous Torque at Standstill of 3.7 Nm deliver consistent rotational power for a variety of dynamic motion profiles. Designed without a blocking brake, this model comes Without blocking brake, optimizing weight and simplifying maintenance cycles. Its standard balancing and proven construction make it an ideal solution for demanding industrial environments.
This servo motor’s technical capabilities are centered on precision feedback and efficient drive integration. Equipped with Digital servo feedback (DSF), the motor provides real-time rotor position and speed control, ensuring smooth commutation and accurate torque delivery. The Motor Size 090 frame optimizes electromagnetic performance, while the Product Type Motor for digital drive controllers ensures seamless interfacing with IndraDrive systems. Electrical connectivity is facilitated through a robust Connector with Connection Direction Left, enabling clean cable routing and straightforward installation. Its standard Housing and reliable thermal characteristics support continuous operation under variable loads.
Operationally, the MDD090A excels in durability and ease of use. The Output Shaft with Keyway Per DIN 6885 sh. 1, 8-68 Edition provides secure torque transmission and compatibility with standard couplings. The integrated Shaft Seal protects internal components from contaminants, enhancing long-term reliability. With a Shaft Type keyway design and Shaft End standard (without side B shaft end) configuration, maintenance is simplified, and replacement parts are standardized across the series. Standard Balancing reduces vibration and noise, while the omission of a holding brake streamlines control algorithms for rapid start-stop cycles.
Integration into modern drive systems is straightforward thanks to the motor’s dedicated design for digital controllers. The MDD090A-N-020-N2L-130PL0 interfaces natively with Bosch Rexroth Indramat’s IndraDrive platform, enabling advanced features such as electronic nameplate recognition and automatic parameter configuration. Its combination of precision feedback, robust mechanical interfaces, and standardized connection protocols makes it ideally suited for applications in robotics, CNC machinery, packaging equipment, and other high-performance automation systems where reliability and accuracy are paramount.

Frequently Asked Questions
For the Bosch Rexroth Indramat MDD090A-N-020-N2L-130PL0, which drives is it typically paired with and what setup advantages result?
It’s used with Rexroth digital intelligent drives (e.g., DDS/DKS/DKC). The DSF feedback stores motor parameters that the drive reads for safe, automatic commissioning.
What does the 130 mm pilot (centering diameter) imply for mounting?
It defines the locating fit for B05/B14 flanges; your machine plate needs a matching 130 mm pilot to control runout. Don’t rely on bolt clearance to center the motor.
What are the implications of selecting no holding brake?
On vertical or suspended loads, the axis won’t be held at power-off—use an external brake or choose a blocking-brake variant. The series offers versions with and without blocking brakes.
Any considerations when coupling a keyed shaft?
Use couplings balanced “with key” to minimize vibration, noting the rotor is supplied with standard balance class N. Poor balance increases bearing load and can excite machine resonances.
How should I manage thermal performance and duty cycle?
Ensure rigid flange mounting to aid heat dissipation and respect the drive’s thermal model during sizing. Liquid-cooled MDD variants exist for higher continuous duty if the application demands it.
