MDD093D-N-040-N2M-130PB0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-040-N2M-130PB0 is a high-performance drive motor from the MDD Synchronous Motors series, designed as a motor for digital drive controllers. Featuring an integrated multiturn absolute encoder and digital servo feedback (DSF), this unit delivers precise position and speed control for automated machinery. With a continuous torque at standstill of 24.0 Nm and a nominal speed rating of 4000 min⁻¹, the MDD093D-N-040-N2M-130PB0 excels in applications requiring consistent torque and rapid response in industrial robotics and conveyor systems.
This synchronous motor boasts a compact motor size of 093 and a motor length code of D, striking a balance between power density and footprint. It includes a robust shaft seal and a standard housing that protect internal components from contaminants, while the keyway shaft type ensures reliable torque transmission. Connection is facilitated via a side-mounted Connector on Connection Direction B, enabling straightforward integration into existing drive architectures. The absence of a holding brake (specified as without blocking brake) reduces weight and simplifies design for applications that do not require mechanical locking under power loss.
Built for durability and ease of installation, the MDD093D-N-040-N2M-130PB0 features standard factory balancing to minimize vibration at high speeds, enhancing system longevity. Its standard shaft end configuration maintains compatibility with a wide variety of couplings and gears, while the integrated feedback systems support seamless communication with Bosch Rexroth digital drives. The motor’s protection elements, including the sealed shaft, improve resistance to dust and moisture, contributing to consistent performance in harsh industrial environments. By combining precise control, robust construction, and efficient feedback integration, this motor enhances productivity and reliability in manufacturing and process automation applications.

Frequently Asked Questions
What happens to control precision if the integrated multiturn absolute encoder loses communication?
If encoder feedback fails, the drive will lose closed-loop position control and may revert to a safe fallback mode such as torque or velocity limiting. Recovery typically requires a reinitialization or homing cycle to reestablish absolute reference.
How does having a sealed shaft and standard housing affect cooling and thermal behavior under high duty?
The seal adds thermal resistance at the shaft interface, which slightly degrades heat dissipation from the rotor; thus at high continuous loads you’ll see higher temperature rise compared to an open-shaft design. Because of that, ambient temperature limits and duty-cycle derating must be carefully considered in thermal modelling.
In a robotic arm, how does the 24 Nm standstill torque of this motor translate into accelerative capability at nominal speed?
The torque available during acceleration (especially near standstill) allows rapid starts and stops, but as speed rises torque capacity will drop with motor constant and voltage limits; thus peak acceleration at full speed is constrained. In design you use the torque-speed curve to size permitted inertias for dynamic axes.
How important is factory balancing “standard” in this motor for high-speed applications?
Standard factory balancing reduces rotor eccentricity and vibration at high rpms, which is critical to avoid resonance and bearing stress in precision systems. For extremely high-speed or low-noise systems you might require a higher balance grade beyond “standard.”
How does keyway shaft type influence coupling selection and backlash control?
A keyway provides positive torque transmission but introduces minor micro-clearance (backlash) in coupling design, so for precision systems you may need zero-backlash couplings or preload mechanisms. The coupling hub must properly match the key width and material to avoid stress concentration or fretting.
