MDD025A-N-100-N2G-040GE0
MDD Synchronous Motors
MDD025A-N-100-N2G-040GE0, Bosch Rexroth Indramat, MDD Synchronous Motors series drive motor delivers high-speed performance in a compact, robust package designed for seamless integration with digital drive controllers. The motor’s 025 size and A length code ensure a lightweight footprint without sacrificing rigidity, while the plain shaft design and standard (without side B shaft end) configuration simplify coupling to downstream equipment. Engineered with a standard housing and standard balancing, this motor maintains optimal vibrational stability across its entire operating range. Featuring a 40 mm centering diameter, the unit aligns precisely in tight assemblies, minimizing installation complexity.
Detailed specifications highlight the motor’s capabilities: a continuous torque at standstill of 0.33 Nm supports reliable holding under load, and a nominal speed of 10000 min⁻¹ enables rapid cycle times. The integrated resolver feedback system provides high-resolution position monitoring, ensuring precise motion control in demanding applications. A shaft seal protects against ingress of contaminants, while the without blocking brake configuration reduces mechanical wear and heat generation. Connectivity is straightforward via the connecting cable with coupling unit, oriented to the left for streamlined cabinet layouts. Tailored for digital drive architectures, this motor for digital drive controllers adheres to stringent Bosch Rexroth Indramat quality standards.
Designed for demanding industrial environments, the MDD025A-N-100-N2G-040GE0 motor integrates seamlessly into multi-axis control systems, reducing commissioning time and cabling complexity. The combination of robust sealing, standard balancing, and precise resolver feedback ensures long-term reliability and consistent performance. Ideal for high-speed positioning, packaging, and assembly machines, this motor maximizes throughput while minimizing downtime.

Frequently Asked Questions
Why is the “without blocking brake” configuration important in thermal and mechanical life terms?
Brakes add friction and generate heat if held frequently or under load, and add wear components; omitting the brake reduces those thermal cycling issues. It also means fewer moving parts to fail, and lower maintenance, though at cost of no built-in fail-safe stop.
What are ambient/environmental requirements for using this motor with shaft seal?
The shaft seal offers protection against dust, liquids, and contaminants, but it also introduces friction, which raises temperature locally; in high ambient temperature (> 40-50°C) or dirty environments, the seal must be cleaned and possibly replaced more often. If ambient exceeds the thermal design or suffers heavy dust, ensure adequate cooling and periodic maintenance of shaft seal.
How does standard balancing vs. precision or special balancing impact vibration and noise at high rpm?
Standard balancing is adequate for most industrial uses; however, for ultra-high rpm or applications sensitive to vibration (e.g. optics, micro-assembly), precision balancing (tight tolerances) reduces lateral and axial vibration. Lower vibration improves life of bearings, coupling, and reduces wear on seals or mechanical misalignments.
What are the integration implications of having the connection cable + coupling unit on the left (or right) side for digital drive controller layouts?
Cable routing affects cabinet space, potential electrical noise, and cable bend radius; if the connection is on a non-ideal side, routing may require bending or extension, increasing cable losses or EMI exposure. Planning for proper cable length, shielding, and strain relief is essential to maintain signal integrity of resolver feedback and power supply.
In multi-axis synchronised systems, how does this motor’s nominal speed of 10000 min⁻¹ impact controller selection and tuning?
High nominal speeds demand that the digital drive controller support fast current and velocity loops, with sufficient bandwidth to handle the electro-mechanical time constants without overshoot. Also, inertia matching (motor + load) and tuning gains must be set carefully to avoid resonance, overshoot or lag, especially when starting/stopping rapidly or with reversing motion.
