MDD093D-N-040-N2M-110GA1
MDD Synchronous Motors
The MDD093D-N-040-N2M-110GA1, Bosch Rexroth Indramat, MDD Synchronous Motors model is engineered as a high-performance Motor for digital drive controllers in demanding automation and motion control applications. This Motor Size 093 unit features Standard Balancing for minimized vibration and a robust Housing that secures internal components against environmental stress. Equipped With blocking brake, it incorporates a **11 Nm** Holding Brake Torque to maintain shaft position under load. The drive-ready package includes a Plain shaft with a Centering Diameter of 110 mm for seamless mechanical coupling.
Built around an integrated multiturn absolute encoder, the motor provides precise position feedback, augmented by digital servo feedback (**DSF**) to streamline real-time control loops. It achieves a Continuous Torque at Standstill of 24.0 Nm and accelerates to a **Nominal Speed of 4000 min⁻¹**, delivering consistent performance across the specified speed range. The Motor Length Code D balance of torque density and compactness optimizes cabinet space without sacrificing thermal capacity. A Shaft Seal protects internal bearings from contamination, while the Connector Connection Type and defined Connection Direction A ease installation and wiring in high-density drive racks.
Integration is simplified through its standardized form factor and compatibility with Bosch Rexroth Indramat digital drives, enabling plug-and-play commissioning and parameter cloning across multiple axes. The sealed construction and high-precision encoder reduce maintenance intervals, ensuring reliable, uninterrupted operation. Ideal for CNC machinery, multi-axis robotics, and synchronised gantries, the MDD093D-N-040-N2M-110GA1 motor maximises throughput with minimal footprint.

Frequently Asked Questions
What mounting tolerances should I allow when bolting the MDD093D-N-040-N2M-110GA1 to an axis?
The centering diameter (110 mm) must align with the machine’s coupling to maintain balance; a misalignment beyond a few hundred microns can introduce vibration and mechanical stress. Use a precision reamed boss or alignment tool to ensure coaxial mounting.
How does the 11 Nm holding brake influence system safety during a power loss?
The brake holds the shaft when unpowered, but its torque is limited—if external forces exceed 11 Nm, slippage may occur. In mission-critical systems, an emergency mechanical lock or secondary brake may be required.
How does the integrated multiturn absolute encoder with DSF improve closed-loop performance?
Because absolute position is retained even after power-off, you eliminate the need for rehoming at startup; high-resolution feedback allows tighter current/velocity control and lower position error.
What are the permissible radial and axial loads on the motor shaft in operation?
The floating bearing on side A absorbs radial loads, while the fixed side B bearing takes axial loads—exceeding those thresholds may shorten bearing life. The MDD planning documentation includes load diagrams for allowable radial/axial forces vs. speed.
What installation caveats exist for connector orientation and cable routing?
The connector direction is fixed upon ordering (Side A in your case), and changing it after delivery is not feasible; cables must be stress-relieved, and the connector housing should be sealed to maintain the IP rating.
