MDD093D-N-040-N2L-110GB1
MDD Synchronous Motors
The MDD093D-N-040-N2L-110GB1 is a high-performance digital AC servo motor from Bosch Rexroth Indramat's renowned MDD Synchronous Motors series, designed for precision motion control in demanding industrial environments. This compact drive unit features a Motor Size 093 with a Motor Length Code D that optimizes space utilization while delivering robust output. The motor incorporates a Centering Diameter of 110 mm for accurate alignment with machine components and a Plain Shaft design for straightforward coupling. Equipped with a Holding Brake offering 11 Nm Holding Brake Torque, the MDD093D model secures the load at standstill, ensuring safety and positional stability. Rated for a Nominal Speed of 4000 min⁻¹, this motor supports rapid acceleration and precise speed regulation across a broad operating range.
Performance is anchored by a high-resolution Digital Servo Feedback (DSF) system that provides real-time encoder data for commutation, rotor position, and speed control. The permanent-magnet rotor produces a Continuous Torque at Standstill of 24.0 Nm, enabling the motor to maintain static loads without drift. Integration of a reliable Shaft Seal protects internal components from contaminants, while the Standard Balancing minimizes vibration and noise, enhancing overall system smoothness. Electrical and mechanical interfaces are standardized: the motor utilizes a side-entry Connection Direction B and an industry-standard Connector type to streamline installation. The Shaft End Standard (without side B shaft end) ensures compatibility with a wide range of couplings and gearboxes, reducing downtime during maintenance.
Designed for seamless integration with digital drive controllers, this Product Type: Motor for digital drive controllers excels in applications requiring high reliability and precise positioning. The Standard Housing construction delivers robust protection and simplifies cooling in continuous-operation settings. Thanks to its proven Bosch Rexroth engineering, the MDD093D provides consistent performance over extended duty cycles, making it ideal for robotics, packaging, and machining centers. With a balanced configuration and comprehensive feedback capabilities, the motor aligns effortlessly with Indramat servo drives, enhancing system responsiveness and throughput. Users benefit from streamlined commissioning, minimal tuning requirements, and the confidence of operating a component backed by global support and spare-parts availability.

Frequently Asked Questions
What B2B applications benefit from the 24 Nm standstill torque with an 11 Nm holding brake?
Vertical axes in packaging, CNC, and robotics can hold position on power-down or fault with the brake while the drive maintains precise torque at standstill for clamping or tensioning. Size the brake for static holding and the drive for dynamic loads to prevent creep or overrun. (Spec-derived plus brake-use guidance.)
Which drives are typically compatible, and why does that matter for peak torque?
MDD motors are designed for Bosch Rexroth digital drive controllers (e.g., DDS family), and achievable maximum torque depends on the specific drive combination. Use the drive/motor selection lists because peak torque limits are binding per approved pairs
Can MDD093D variants be paired with absolute positioning without external homing hardware?
Yes—choose DSF with integrated multiturn absolute encoder to retain position across power cycles and eliminate homing switches. Verify your drive supports the DSF/MTG variant before ordering.
What alignment and coupling choices are recommended with the 110 mm centering (pilot) and plain shaft?
Use the pilot for concentric alignment and select a backlash-free, torsionally stiff coupling; if using a keyed option, balance with the full key per DIN guidance. Misalignment increases bearing load and degrades feedback accuracy at high speed.
Is the integrated holding brake suitable for emergency stopping and dynamic braking?
No—the holding brake is for static holding; it is not a working/emergency brake and wears quickly if used for dynamic stops. Drive logic controls release/clamp timing and can be parameterized to clamp on fault or E-stop for safer load retention.
