MDD025A-N-100-N2G-040GC0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD025A-N-100-N2G-040GC0 from the MDD Synchronous Motors series is a precision-engineered Motor for digital drive controllers built to deliver reliable performance in demanding automation environments. This Motor Size 025 frame, combined with a Motor Length Code A, provides a compact footprint that simplifies cabinet integration and mechanical mounting. The motor features a Centering Diameter 40 mm and a standard Housing, ensuring seamless alignment with legacy equipment and new installations. With Resolver feedback built in, users benefit from accurate position sensing and fast dynamic response across the full speed range.
Striking a balance between power density and control precision, the MDD025A delivers a Continuous Torque at Standstill of 0.33 Nm and operates at a peak Nominal Speed of 10000 min⁻¹ for high-throughput applications. The With shaft seal configuration safeguards internal components against contaminants, while the Plain shaft design allows for versatile coupling options. Connectivity is handled via a Connecting cable with coupling unit on Connection Direction Side A, which streamlines installation and reduces assembly time. Standard Balancing and a Without blocking brake Holding Brake option ensure smooth operation and low vibration, even at maximum rotational speeds.
Engineered for compatibility and ease of use, this motor supports straightforward integration into digital servo platforms and reduces setup complexity with its uniform mechanical interfaces. The Standard (without side B shaft end) design minimizes non-essential features, focusing on core functionality and long-term durability. Ideal for precision indexing, pick-and-place machines, and compact robotic modules, the MDD025A-N-100-N2G-040GC0 meets the rigorous demands of modern industrial automation with consistent, repeatable performance.

Frequently Asked Questions
What does the continuous torque at standstill (~0.33 Nm) imply for system sizing and motor heating during a stationary load?
It means the motor can sustain 0.33 Nm indefinitely without rotating; if your application holds higher torque at zero speed, you’ll need an external brake or oversize the motor. Standstill torque also causes heat in the windings—adequate cooling or intermittent operation is essential to avoid overheating when stationary.
How fast can this motor accelerate from standstill given its inertia and torque specs, and what does that mean for motion profiles?
With 0.33 Nm standstill torque and likely low rotor inertia (typical for frame 025 with plain shaft), you can expect rapid acceleration up to high speed; motion profiles can include short settling times. But you must ensure the drive controller supplies sufficient current, and that mechanical loads don’t exceed torque capacity throughout the ramp to avoid stalling or overshoot.
What are the advantages and integration concerns of using the model MDD025A-N-100-N2G-040GC0 (Bosch Rexroth) in B2B applications like pick-and-place or indexing machines?
Advantages include compact footprint, high speed, precise feedback (resolver), and reliable mounting interfaces which reduce engineering and downtime in production machines. Concerns include ensuring proper servo drive matching, thermal control in continuous duty, and implementing safety brakes or interlocks in absence of a built-in holding brake.
What does the continuous torque at standstill (~0.33 Nm) imply for system sizing and motor heating during a stationary load?
It means the motor can sustain 0.33 Nm indefinitely without rotating; if your application holds higher torque at zero speed, you’ll need an external brake or oversize the motor. Standstill torque also causes heat in the windings—adequate cooling or intermittent operation is essential to avoid overheating when stationary.
How does the 10 000 min⁻¹ nominal speed affect coupling and bearing selection?
High nominal speed increases centrifugal forces on shaft and any uncoupled masses, so flexible or balanced couplings are required to avoid vibration or premature bearing wear. Also, bearing ratings must handle both radial and axial loads at high rpm with minimal lubrication failure.
