MDD090A-N-030-N2L-110GL1
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090A-N-030-N2L-110GL1 from the MDD Synchronous Motors series delivers precision performance as a motor for digital drive controllers. This Motor Size 090 frame with Motor Length Code A is engineered to provide a continuous torque at standstill of 3.7 Nm and maintains a nominal speed of 3000 min⁻¹ under rated conditions, offering an optimized torque-to-inertia ratio for dynamic indexing. Featuring a centering diameter of 110 mm, the motor’s compact profile and standard housing simplify mechanical integration in confined enclosures. Its robust plain shaft design ensures reliable torque transmission for high-speed automation tasks.
Advanced control is enabled by native digital servo feedback (DSF), ensuring sub-micrometer position resolution and seamless closed-loop operation. The unit incorporates a holding brake with a holding brake torque of 6.5 Nm, delivering secure load locking during power-off states and emergency stops. Standard balancing and a factory-installed shaft seal protect against vibration and environmental ingress, while the left connection direction and detachable connector interface streamline wiring and maintenance. A standard (without side B shaft end) renders installation straightforward across legacy and modern machine platforms.
Bosch Rexroth’s quality assurance and modular design ensure that the MDD090A-N-030-N2L-110GL1 meets stringent industrial requirements and simplifies commissioning. This synchronous motor offers dependable torque density, precise feedback, and versatile mounting options for OEMs and system integrators focused on high-performance digital motion control.

Frequently Asked Questions
What are the implications of the 3.7 Nm continuous torque at standstill for dynamic indexing in high-speed applications?
At standstill, the motor can hold or begin moving loads up to ~3.7 Nm without slipping, which enables precise start/stop control in indexing tasks. In dynamic applications, oversizing for peak torque is still required since acceleration phases demand more than continuous torque.
What practical benefits does Digital Servo Feedback (DSF) bring compared to analog or resolver feedback in motion control systems?
DSF provides higher resolution in position and velocity, reducing error and enabling tighter loop gains, which improves responsiveness and reduces overshoot. Also, because the feedback is digital, it is less prone to signal degradation over distance or due to electrical noise, which aids in long cable runs or harsh environments.
What cooling or thermal management considerations arise from its nominal speed of 3000 min⁻¹ and compact frame?
At 3000 rpm, losses from windage, bearing friction, and copper/iron heating can accumulate, so sufficient thermal dissipation (via housing, mounting structure, or forced air) is needed to avoid overheating. In confined spaces, allowing free air paths around the motor or using heatsinks/massive mounting flanges helps maintain thermal stability.
How does the torque-to-inertia ratio of this motor affect acceleration and deceleration in high-performance axes?
A favorable torque-to-inertia ratio means the motor can deliver rapid acceleration / deceleration for a given drive without being slowed by its own rotor inertia. This improves cycle times and responsiveness, particularly in packaging, pick-and-place, or robotics where swift motion changes are frequent.
What are the environmental sealing and vibration protection features, and how do they affect long-term reliability?
The shaft seal protects internal components (bearings, windings, encoder) from dust and moisture ingress, reducing corrosion and mechanical wear. Standard balancing reduces vibration amplitude, minimizing mechanical fatigue and improving bearing life when used at nominal speeds.
