MDD025A-N-100-N2G-040GB1
MDD Synchronous Motors
MDD025A-N-100-N2G-040GB1, Bosch Rexroth Indramat, MDD Synchronous Motors present a robust, high-dynamic drive solution optimized for digital motion control. The motor’s compact design integrates a plain shaft and standard housing to ensure straightforward installation into existing machine frames. Engineered for precise, repeatable motion, it delivers seamless performance when paired with Bosch Rexroth digital drive controllers. Its resilient build and proven Indramat lineage guarantee maintenance-friendly operation in demanding industrial environments.
Designed for tight-tolerance applications, this motor provides a Continuous Torque at Standstill of 0.33 Nm and a Nominal Speed of 10000 min⁻¹, sustaining high-speed operation without compromise. A Holding Brake with Holding Brake Torque of 1.0 Nm secures loads instantly when power is removed. The Resolver Feedback system offers sub-arcminute position resolution, while Standard Balancing minimizes vibration at peak rpm. The shaft features a Shaft Seal for dust and particle ingress protection, and a Plain Shaft end with Centering Diameter of 40 mm for direct coupling. A side-mounted connector on Connection Direction: Side B uses a standardized Connection Type: Connector for rapid wiring. Compact footprint is achieved through Motor Size: 025 and Motor Length Code: A, enabling high-density machine layouts.
Integration into Bosch Rexroth automation platforms is seamless, leveraging native compatibility with digital drive controllers and common feedback protocols. The motor’s rugged construction and protective sealing deliver exceptional reliability under continuous-duty cycles. Ideal for packaging machines, labeling systems, and precision indexing tables, this synchronous motor streamlines commissioning and maximizes uptime.

Frequently Asked Questions
What are the thermal management challenges for continuous-duty cycles in motors of this size and speed?
Continuous high-speed operation generates losses in winding, core, and bearings; without adequate cooling or ambient conditions (temperature, airflow), the motor housing temperature can rise beyond spec, reducing insulation life and potentially triggering protection. A good design must consider how to dissipate heat—via convection, possibly surface cooling, proper mounting, and drive duty cycles.
How does the connector orientation (side B / side connector) impact cable routing and control cabinet layout?
The side B / connector positioning determines where the power and feedback cables exit; that affects how cables are routed through machine frames, how connectors are accessed for servicing, and how strain reliefs and shielding are arranged. Poor orientation can lead to sharp bends, cable interference, or added EMI noise if feedback cables run near power lines.
In B2B applications like packaging or precision indexing, what performance trade-offs arise between holding torque, speed, and feedback resolution?
In these applications you often need rapid acceleration and deceleration (favoring high speed), exact stopping (favoring high resolution feedback), and safe holding when idle or during tooling changes (favoring strong holding torque). Improving one tends to challenge the others—for example, a high holding brake may increase inertia or size, and very high resolution feedback may be more expensive or require more careful wiring and calibration.
What role does the holding brake with 1.0 Nm torque play in safety and emergency stop scenarios?
The holding brake ensures the shaft is locked when power is removed or in fault conditions, preventing drift or load drop-off; with 1.0 Nm torque it must exceed external moments or gravity loads for safe stops. However, it is not a service duty component—it wears, requires correct drive actuation, and may need secondary safety backups in critical systems.
How does resolver feedback enhance positional accuracy in this motor, and what limitations does it have?
A resolver gives robust analog feedback resistant to electrical noise and temperature shifts, typically yielding resolution on the order of arc-minutes; it's useful for high dynamic control. The trade-off is that resolvers often require more signal conditioning, may have lower resolution than certain optical absolute encoders, and their installation (alignment) must be precise to avoid phase errors.
