MDD093D-N-040-N2M-130PA1
MDD Synchronous Motors
MDD093D-N-040-N2M-130PA1, designed by Bosch Rexroth Indramat, belongs to the robust MDD Synchronous Motors family. This motor for digital drive controllers is engineered for precision in demanding applications, combining a compact footprint with high-performance features. Equipped with an integrated multiturn absolute encoder and digital servo feedback (DSF), it guarantees repeatable positioning and tight speed control. The standard housing and keyway shaft type further simplify installation and mechanical integration.
In operation, the motor delivers a continuous torque at standstill of 24.0 Nm and a holding brake torque of 11 Nm provided by the integrated blocking brake. The nominal speed rating of 4000 min⁻¹ ensures responsive dynamic performance across a wide speed range, while the centering diameter of 130 mm eases direct mounting to gearboxes or couplings. Standard balancing reduces vibration and noise, and the shaft seal protects internal components against contaminants. Connection is made via a side-A connector of sturdy connection type, streamlining wiring and minimizing downtime.
With its high-grade blocking brake and digital feedback, the MDD093D-N-040-N2M-130PA1 motor integrates seamlessly into automated systems, enhancing reliability and repeatability. Conforming to Bosch Rexroth’s exacting quality standards, it delivers consistent performance under continuous load conditions. This motor is ideal for machine tools, packaging lines, and robotics where precise motion control and rapid response are critical.

Frequently Asked Questions
What are trade-offs due to the keyway shaft type?
A keyway ensures torque transmission without slippage but introduces stress concentration and reduces fatigue life slightly; good fillet design and stress relief are critical.
In what way does digital servo feedback (DSF) improve control bandwidth?
DSF supplies high-resolution real-time feedback on position and velocity, enabling tighter loop tuning and higher dynamic response compared to analog encoders.
How does permanent magnet motor construction affect inertia and responsiveness?
A permanent-magnet rotor yields lower rotor inertia for a given torque class, improving acceleration and deceleration performance in responsive motion tasks.
What is the importance of the shaft seal in harsh environments?
The seal excludes contaminants (like dust, coolant) from entering the bearing/feedback path, preserving long-term reliability in industrial settings.
How does the 11 Nm blocking brake influence safety during downtime?
The brake applies mechanical locking without power, preventing motion drift when the drive is idle or powered off. It must be sized so the static load torque never exceeds the brake torque.
