The Bosch Rexroth Indramat MDD090C-N-030-N2M-110GB1 belongs to the renowned MDD Synchronous Motors series and is engineered as a high-performance motor for digital drive controllers. With a motor size of 090 and a nominal speed of 3000 min⁻¹, this unit delivers precise motion control in demanding industrial environments. It features a continuous torque at standstill of 10.4 Nm and a center­ing diameter of 110 mm, ensuring reliable starting torque and seamless integration into rotary assemblies. The primary function of this motor is to power synchronous drive systems with rapid response and consistent torque output.



Designed for digital servo applications, the MDD090C-N-030-N2M-110GB1 incorporates an integrated multiturn absolute encoder and digital servo feedback (DSF) for precise position and speed feedback. The inclusion of a blocking brake provides a holding brake torque of 6.5 Nm, offering secure load retention when power is removed. The housing is of standard construction with a shaft seal to protect internal components from contamination. The unit’s plain shaft design and standard (without side B shaft end) configuration simplify mounting and reduce the need for custom adapters.



This motor’s connection type is via a reliable connector oriented in the side B direction, facilitating straightforward cabling and maintenance. Its shaft seal and standard housing ensure durability in harsh industrial environments, while the standard balancing minimizes vibration and noise during high-speed rotation. The precise center­ing diameter and digital feedback options guarantee compatibility with modern CNC and PLC systems. By combining robust construction, advanced feedback technology, and secure brake functionality, the MDD090C-N-030-N2M-110GB1 enhances operational efficiency and reduces downtime in automation and motion control applications.

How does the integrated multiturn absolute encoder affect system homing and recovery?

Because absolute position is retained through power cycles, the system does not require a full homing run at startup, improving startup speed and reducing mechanical stress. It also allows safe power cycling with consistent feedback integrity.

What considerations does the 6.5 Nm blocking brake impose on dynamic performance?

The brake adds inertia and mechanical coupling friction—brake release times and wear must be managed in high-cycling systems. Also, the drive control must account for the brake torque when transitioning between hold and motion modes.

How critical is the centering diameter of 110 mm when replacing or retrofitting servos?

Matching the centering or pilot diameter ensures concentricity and alignment, minimizing runout and vibration. If the replacement motor deviates, you risk bearing loads, shaft misalignment, or coupling binding.

What impact does “standard balancing” have on vibration and permissible operating speed?

Standard balancing limits rotor imbalance to a level acceptable for the rated speed, reducing vibration and bearing stress. For higher-speed use or precision applications, one may need a “precision balance” upgrade.

How should one size the drive and cabling given the motor’s digital servo feedback interface?

The drive must support DSF (digital servo feedback) protocol and supply enough current/headroom for peak demands. Feedback and power cables should be shielded and routed separately to avoid EMI degrading the digital encoder signals.
