MDD090C-N-030-N2L-130PB2
MDD Synchronous Motors
MDD090C-N-030-N2L-130PB2, Bosch Rexroth Indramat, MDD Synchronous Motors delivers precision motion in a robust design. The MDD090C-N-030-N2L-130PB2 integrates a Digital servo feedback (DSF) system to ensure accurate position and velocity control under dynamic loads. With a compact Motor Size of 090 and a Centering Diameter of 130 mm, it seamlessly fits into standard machine frames. The motor’s Housing is designed for industrial environments, providing a durable platform for demanding applications.
In continuous operation at standstill, the unit generates a Continuous Torque at Standstill of 10.4 Nm, while the Holding Brake Torque of 11.0 Nm secures loads during power-off conditions. Balanced to a Standard specification, this motor runs smoothly up to its Nominal Speed of 3000 min⁻¹ without excessive vibration. A keyway shaft type, protected by a With shaft seal arrangement, prevents ingress of contaminants and maintains alignment under high-speed rotation. Side-mounted Connector interface on Connection Direction B simplifies cable routing and quick installation.
Engineers will appreciate the motor’s compatibility with Bosch Rexroth Indramat digital drive controllers, offering plug-and-play integration into existing automation networks. The rugged construction and precise feedback loop enhance system reliability, reducing downtime in mission-critical processes. Ideal for robotics, packaging systems, and CNC machinery, the MDD090C-N-030-N2L-130PB2 ensures consistent performance and streamlined commissioning across diverse industrial applications.

Frequently Asked Questions
How does the digital servo feedback (DSF) affect closed-loop control performance?
The DSF option provides high resolution (up to ~2,097,152 increments per rev) and ±0.5 angular minute accuracy, enabling very fine position control and reduced lag in servo loops.
What practical limitations does the 10.4 Nm continuous torque at standstill impose in motion profiles?
That value defines the maximum static torque the motor can sustain indefinitely without heating; in dynamic profiles you must account for acceleration and deceleration, which require higher instantaneous torque. In high-speed or high-inertia loads, you’ll need safety margins above 10.4 Nm to avoid thermal overload.
What role does the built-in 11.0 Nm holding brake play in application safety?
The holding brake locks the shaft mechanically when power is removed, preventing drift or fall of loads in power-off scenarios. It ensures torque retention independent of motor control, which is vital for vertical axes or suspended systems.
How does standard “balancing” affect operational vibration at 3000 min⁻¹?
Standard balancing implies the rotor is balanced to generic tolerances, which typically suffices for many CNC or packaging tasks. But if your application demands ultra low vibration (e.g. high-precision spindle), you may need a higher balancing grade (e.g. G2.5) to reduce mechanical resonance.
What are the implications of using a keyway shaft with seal under high duty cycles?
Keyway shafts facilitate secure coupling torque transfer but can produce stress concentrations; the shaft seal protects from ingress of contaminants. In high-duty or shock-load environments, ensure proper fillet geometry and choose coupling types that minimize edge loading to the key.
