MDD025A-N-100-N2K-040MC1
MDD Synchronous Motors
The MDD025A-N-100-N2K-040MC1, produced by Bosch Rexroth Indramat, is part of the high-performance MDD Synchronous Motors line. This digital AC servo motor features a rigid Product Type: Motor for digital drive controllers architecture and a compact Motor Size: 025 housing. It delivers precise motion through an integrated impulse absolute encoder system coupled with resolver feedback, ensuring accurate rotor position and speed control. Equipped with a standard Housing design and side-A connection direction, it integrates seamlessly into existing drive setups.
Focusing on key performance figures, the motor provides a Nominal Speed: 10000 min-1 and a continuous Continuous Torque at Standstill: 0.33 Nm, complemented by a robust Holding Brake Torque: 1.0 Nm from the blocking brake. The shaft is manufactured per DIN 6885 sh. 1, featuring a Shaft Type: keyway end with a Centering Diameter: 40 mm for secure load coupling. A standard balancing grade minimizes vibration at high speeds, while the Encoder: Integrated absolute encoder and Motor Feedback: Resolver feedback ensure rapid commutation and precise closed-loop control. Connections are handled via a connecting cable with coupling unit, simplifying installation and maintenance.
Engineered for reliability and ease of use, the MDD025A-N-100-N2K-040MC1 omits a shaft seal and side-B shaft end to reduce complexity and weight. Its durable construction and standardized mounting dimensions enable rapid replacement and compatibility across multiple axes in a motion control system. Ideal for high-speed indexing, packaging, and pick-and-place applications, this motor delivers consistent performance and long-term stability in demanding industrial environments.

Frequently Asked Questions
How does the 1.0 Nm holding brake torque influence safety and mechanical load when the motor is stopped under load?
The holding brake must exceed the highest external torque present when stationary to prevent drift; also, its engagement/disengagement time and mechanical wear will affect cycle reliability in B2B continuous applications like packaging lines.
Are there thermal limitations when using this motor close to its standstill continuous torque over long durations?
Yes; holding relatively high torque at standstill generates heat that is harder to dissipate (no airflow), so ambient temperature, duty cycle, and possible additional cooling must be considered to avoid overheating.
How critical is the keyway shaft under high dynamic loads in robotic arms, and what alignment precautions are needed?
The keyway ensures torque transmission and positioning under load, but misalignment or improper shaft coupling can introduce vibrations; precision mounting and ensuring tolerance compliance for run-out and shaft flatness are important.
How does the absence of a shaft seal affect environmental resilience and maintenance?
Without a shaft seal, ingress of dust, moisture, or contaminants is more likely at the shaft interface, which can degrade bearings or degrade encoder performance; clean operating environment or additional sealing mechanisms may be needed.
What B2B performance trade-offs should be considered between using this motor versus a larger one with higher torque for continuous operation?
While this motor is compact and high speed, a larger motor gives more torque margin, longer thermal headroom, and possibly smoother motion under load; for long duty cycles or heavier payloads, using a motor with more torque or gearing may improve overall system reliability.
