MDD090A-N-020-N2L-130PR2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090A-N-020-N2L-130PR2 is part of the MDD Synchronous Motors series, designed as a motor for digital drive controllers. This motor combines a robust holding brake torque of 11.0 Nm with a continuous torque at standstill of 3.7 Nm, ensuring secure stopping and stable holding under load. Featuring a key centering diameter of 130 mm, it integrates seamlessly into standardized drive systems.
Engineered for precision motion control, the MDD090A-N-020-N2L-130PR2 has a motor size of 090 and a motor length code of A, fitting compact machine designs without sacrificing performance. Its nominal speed of 2000 min⁻¹ provides rapid response for high-speed applications, while the standard housing offers necessary protection in industrial environments. The motor employs digital servo feedback (DSF) for accurate position sensing and closed-loop control, and a keyway shaft type for positive torque transmission. With a shaft end specified as standard (without side B shaft end), it ensures compatibility with common couplings and accessories.
Additional features include standard balancing for smooth operation and a shaft seal to prevent contamination in harsh conditions. The motor’s connection direction is on the right side, using a reliable connector interface for fast, error-free installation. Equipped with a blocking brake, it guarantees immediate stopping and holds loads securely when de-energized, enhancing safety and reducing maintenance. As a purpose-built component in the MDD family, it delivers high durability and efficiency in closed-loop drive systems. Employing proven Bosch Rexroth quality, the MDD090A-N-020-N2L-130PR2 offers reliable performance and seamless integration in demanding industrial automation applications.

Frequently Asked Questions
How does a 2000 rpm nominal speed affect gearbox selection and inertia matching?
Select ratios that keep reflected load inertia within the drive’s tuning range; the MDD’s low-inertia rotor supports fast acceleration with moderate ratios. This helps avoid oscillation and reduces servo gain demands.
What does the 130 mm centering diameter change for installation accuracy?
It’s the primary locating feature; maintain tight fit and runout to prevent bearing side-loads and misalignment. Follow the MDD project-planning guidelines for mounting practices.
What environmental protection can I expect, and when is a shaft seal necessary?
MDD motors are typically IP65 at housing/connectors; unsealed shafts can be lower (e.g., IP50), so specify a shaft seal in dusty/spray areas. This preserves ingress protection at the rotating interface.
Are there cable-length or EMC constraints when machine-mounting the drive and motor?
Machine-side mounting reduces interference-prone cable runs; observe shielding and routing rules. DDC guidance caps motor power-cable length at ~75 m to maintain EMC and voltage-drop margins.
Where is this motor series commonly deployed in B2B machinery?
Transfer lines, indexing/finishing stations, and other CNC/automation cells that need precise closed-loop motion and secure axis holding are typical targets. It’s frequently paired with DIAX/DDC/DDS systems in such equipment.
