MDD090A-N-020-N2M-110GA1, Bosch Rexroth Indramat, MDD Synchronous Motors delivers precision performance in a robust, compact package tailored for demanding industrial automation. This motor features an Integrated multiturn absolute encoder coupled with Digital servo feedback (DSF) to ensure accurate positioning and high-fidelity feedback. The unit’s Standard housing and 110 mm centering diameter allow straightforward integration into multi-axis gantries and robotic modules. With a Standard (without side B shaft end) Plain shaft, it provides direct-drive compatibility without additional adapters.



Engineered for continuous-duty applications, the motor achieves a Continuous Torque at Standstill of 3.7 Nm and an intermittent Holding Brake Torque of 6.5 Nm via its integrated blocking brake. It runs at a Nominal Speed of 2000 min⁻¹ and incorporates Standard balancing to minimize vibration and acoustic noise. The With shaft seal design protects internal bearings and windings from dust and moisture, while the Side A Connector interface streamlines cabling in crowded control cabinets. Its Motor Length Code A optimizes axial space, and the product’s classification as a Motor for digital drive controllers ensures turnkey compatibility with Rexroth’s drive electronics.



Designed for rapid deployment, the MDD090A-N-020-N2M-110GA1 integrates seamlessly into existing Bosch Rexroth control systems, reducing engineering effort. Its rugged sealing and blocking brake deliver reliable operation in harsh factory conditions, cutting maintenance intervals. Ideal for robotics, automated handling, and precision assembly tasks, this motor offers consistent torque output and uptime, boosting productivity across diverse applications.

How does a plain output shaft influence coupling and backlash?

Plain shafts are designed for friction-locked clamping sets, enabling backlash-free torque transfer without keys. Indramat’s planning guidance explicitly recommends plain shafts for this reason.

What does the 110 mm centering (pilot) diameter mean for installation?

It’s the locating diameter that aligns the motor concentrically to the machine flange, controlling runout. A correct pilot fit reduces misalignment-induced bearing loads and vibration.

What environmental protection can I expect with a shaft seal?

MDD motors with shaft sealing achieve IP65—dust-tight and resistant to water jets—suitable for areas with chips, coolant spray, or washdown splash. Without the seal, protection is reduced.

What should I watch for with belt or pulley loads on the shaft?

Observe the radial-force curves versus pulley diameter/speed and keep the pulley as close to the bearing as practical to minimize load. Bearing life calculations and axial-load limits are provided in the planning manual.

What control benefits come from Digital Servo Feedback (DSF) with an absolute encoder?

DSF delivers high-resolution position data for tight loops and fast settling; adding the multiturn absolute option eliminates homing errors after outages. Both feedback versions share the same mechanical envelope.
