MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-040-N2L-110PB1 is a high-performance member of the MDD Synchronous Motors series designed for precision motion control in industrial automation. This Digital AC Servo Motor incorporates a permanent-magnet rotor and an integrated encoder for commutation, rotor position and speed measurement. Rated for a nominal speed of 4000 min⁻¹ and equipped with a holding brake torque of 11 Nm, the MDD093D-N-040-N2L-110PB1 delivers consistent start-stop capability under dynamic loads. Its compact design features a motor length code D and a centering diameter of 110 mm, optimizing installation in space-constrained applications. Equipped with Digital Servo Feedback, this motor ensures high-resolution feedback for advanced motion algorithms.
Technical specifications for the MDD093D-N-040-N2L-110PB1 include a motor size of 093 and a standard housing with standard balancing for smooth operation. The motor provides continuous torque at standstill of 24.0 Nm and includes a blocking brake with holding brake torque of 11 Nm. The shaft seal protects internal components while the shaft type (keyway) conforms to DIN 6885 sheet 1, sh. 8–68 edition for reliable torque transmission. Connection is made via a side B connector, ensuring straightforward integration. The motor feedback system is specified as Digital Servo Feedback (DSF) and it is classified as a motor for digital drive controllers with a standard (without side B) shaft end finish.
Operationally, the MDD093D-N-040-N2L-110PB1 excels in dynamic positioning tasks, leveraging its encoder-based commutation to maintain tight speed regulation and positional accuracy. The combination of a permanent-magnet rotor and digital feedback enables rapid response to acceleration and deceleration commands. Connection via a robust connector interface in the Side B direction simplifies cabling and maintenance in harsh industrial environments. Standard balancing reduces vibration, while the integrated shaft seal extends service intervals by preventing ingress of contaminants. This motor reliably supports continuous operation cycles, making it suitable for high-duty applications.
System integration is streamlined through compatibility with Bosch Rexroth Indramat digital drive controllers, allowing seamless communication and parameterization. The MDD093D-N-040-N2L-110PB1 supports advanced diagnostics and tuning functions, enabling predictive maintenance and minimizing downtime. Its compact footprint and 110 mm centering diameter facilitate direct replacement in retrofit projects or new machine designs. Ideal for packaging machines, CNC machining centers, and robotic manipulators, this servo motor meets the rigorous demands of modern automation systems.

Frequently Asked Questions
What mounting tolerances should I observe given the 110 mm centering diameter?
The 110 mm centering diameter demands tight concentricity (typically < 0.02 mm) to prevent bearing loads and vibration; misalignment beyond that will degrade precision and life. Proper shaft support and rigid flange mounting help maintain this tolerance in real systems.
How does the 24 Nm continuous torque at standstill affect thermal design?
Holding a load at standstill continuously generates I²R losses (~heat) in the windings, so you must ensure adequate cooling or duty cycling to avoid overheating. In practice, mounting the motor on a heat-conductive structure and allowing airflow is critical to maintain safe temperature rise.
What considerations arise from the 11 Nm blocking-brake when sizing backup safety circuits?
The brake’s 11 Nm torque limits the maximum resisting load you can safely hold during power failure; any external torque larger than 11 Nm must be supported by mechanical locks or safety circuits. Additionally, the brake coil must be dimensioned in the drive electronics to provide reliable engagement/disengagement under worst‐case voltage drop.
How will the motor’s digital servo feedback alter controller selection?
Digital servo feedback (DSF) gives high-resolution position and speed signals directly, which means your controller must support the DSF interface (encoder, commutation, diagnostics). It simplifies wiring (less analog scaling) but requires digital signal conditioning and compatible drive firmware.
If I increase speed near 4000 min⁻¹, what dynamic limitations should I check?
At high rpm, rotor centrifugal stress, bearing life, and resonance become critical; you must evaluate the motor’s maximum permissible rotational speed and consider modal analysis in your mechanical system. Also verify that the feedback and drive electronics maintain accuracy at those speeds.
