MDD090C-N-030-N2M-110PB1
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090C-N-030-N2M-110PB1 is part of the MDD Synchronous Motors series, designed as a high-performance motor for digital drive controllers. It delivers a Nominal Speed of 3000 min⁻¹ and provides a Continuous Torque at Standstill of 10.4 Nm for demanding industrial motion control tasks. With an integrated multiturn absolute encoder and Digital Servo Feedback (DSF), this unit excels in precision positioning and torque regulation, making it ideal for CNC machines, robotics, and press feeds.
Featuring an integrated multiturn absolute encoder for seamless digital feedback, this servo motor ensures high-resolution position tracking and smooth velocity control. The built-in blocking brake offers a Holding Brake Torque of 6.5 Nm, preventing unwanted motion and securing loads in safety-critical applications. The Shaft Type is a robust keyway design with an integrated Shaft Seal, enhancing mechanical stability and preventing contamination. Connection is achieved via a side-mounted connector (Connection Direction: Side B), simplifying wiring and maintenance. Standard balancing and a Centering Diameter of 110 mm ensure low vibration and optimal alignment within machine assemblies.
Constructed with a standard housing and side B connector interface, the MDD090C motor provides broad compatibility across automation platforms. Its keyway shaft and sealed design improve durability under harsh environmental conditions, reducing downtime and maintenance costs. The digital feedback system and integrated encoder enhance energy efficiency by minimizing overshoot and ensuring precise torque delivery. As a purpose-built servo motor with rapid response and secure load holding, the MDD090C-N-030-N2M-110PB1 delivers reliable performance, improved throughput, and enhanced safety in industrial automation deployments.

Frequently Asked Questions
How does the 6.5 Nm holding brake affect system safety and motion locking?
The holding (blocking) brake ensures the motor shaft resists movement when power is off, but its 6.5 Nm limit means it can be overpowered if external load torque exceeds that. You must design gear ratios, backlash, and external forces so that the brake capacity remains adequate during emergency stops or idle states.
What are the implications of the 110 mm centering diameter in mounting alignment?
The large centering diameter ensures better positional repeatability and stability for direct mounting of machine frames or couplings, reducing alignment error. It also demands sufficient clearance in your mounting structure and compatibility with mating flanges.
How should you manage heat dissipation given the motor’s natural convection cooling?
Since the motor relies on surface cooling (no forced fan), you must ensure free airflow around the motor and avoid enclosure restrictions; ambient temperature above 45 °C or restricted flow requires torque derating. The motor’s spec sheet notes derating up to 55 °C and altitudes to 5000 m as possible with reduced output
How does the sealed keyway shaft with shaft seal affect coupling and reliability?
The shaft seal protects against contaminants and helps maintain performance in harsh environments, but the keyway requires precise coupling alignment to avoid stresses. When coupling to gearboxes or pulleys, rigid alignment, minimal radial misalignment, and correct key tolerances are essential to avoid premature wear.
For the motor MDD090C-N-030-N2M-110PB1 by Bosch Rexroth, what considerations apply to its braking and motion applications?
Because the integrated brake only holds 6.5 Nm, it’s insufficient for high inertial loads—so you may need a mechanical lock or gearbox with brake for heavy duty arrest. Also, ensure your control system issues correct brake-release timing relative to servo enabling to avoid cogging torque interfering with motion.
