MDD093D-N-040-N2L-130PB2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-040-N2L-130PB2 from the MDD Synchronous Motors series is a high-performance digital AC servo motor designed for precision motion control. This Motor Size 093 unit features a Motor Length Code D and a robust Housing Standard construction, delivering mechanical integrity in demanding environments. With a Centering Diameter 130 mm and an integrated encoder system, the motor ensures accurate rotor positioning and repeatable dynamic response. The Shaft Type keyway per DIN 6885 standard, combined with a Shaft Seal, guarantees reliable torque transmission and protection against contaminants.
Equipped with a Continuous Torque at Standstill 24.0 Nm rating and a Nominal Speed 4000 min−1, the MDD093D offers substantial torque reserve for rapid acceleration and deceleration cycles. Its advanced Motor Feedback Digital servo feedback (DSF) feedback system enables precise commutation and closed-loop speed control. The inclusion of a Holding Brake with blocking brake rated at Holding Brake Torque 22 Nm provides smooth load holding and safe standstill operation. Standard Balancing ensures minimal vibration and noise, maintaining stability at high rotational speeds.
Connectivity and integration are streamlined through a Connection Type Connector interface on Connection Direction Side B, while the Shaft End Standard (without side B shaft end) simplifies coupling arrangements. As a purpose-built Product Type Motor for digital drive controllers, this servo motor is optimized for use with Bosch Rexroth Indramat drives and control platforms. Its combination of robust mechanical features, precision servo feedback, and reliable holding brake functionality makes the MDD093D-N-040-N2L-130PB2 an ideal solution for automated assembly, robotics, and high-speed indexing applications.

Frequently Asked Questions
What precautions are needed for shaft seal and keyway shaft under contaminant exposure?
The shaft seal helps protect internal mechanics from dust or spray, but in harsh or high-humidity environments you should verify gasket compatibility and consider drainage or purge features to prevent seal breach.
What upgrade or servicing concerns should I check for Bosch Rexroth Indramat MDD093D-N-040-N2L-130PB2?
Ensure you use factory-certified service and genuine spare parts from Bosch Rexroth, because improper repairs or third-party components risk long-term reliability issues.
What rotor inertia or dynamic constraints should I budget for in a high-speed robotic pick-and-place?
The motor’s own inertia vs the load inertia ratio must stay low (ideally < 10:1) to preserve acceleration, and any gearbox, coupling, or external mass needs careful consideration to avoid slowing down motion response.
How does “standard balancing” affect max RPM operation and vibration?
Standard balancing typically supports your specified nominal speed with minimal vibration, but pushing toward upper speed limits without enhanced balancing may introduce resonances or bearing wear over time.
What are key design considerations when driving the 4000 RPM nominal speed?
You must ensure the servo drive can supply sufficient current without saturation and control commutation timing precisely—any lag in feedback or delay in switching may degrade torque and dynamic performance.
