MDD025A-N-100-N2G-040FL1
MDD Synchronous Motors
The MDD025A-N-100-N2G-040FL1, Bosch Rexroth Indramat, MDD Synchronous Motors is a high-performance motor designed for synergy with digital drive controllers. It features a Standard housing and Standard balancing to ensure uniform vibration profiles and long service life. The motor is classified as Motor for digital drive controllers and accepts a Connector style interface for simplified commissioning. Engineered without a shaft seal and with a Plain shaft, the drive optimizes both weight and cost without compromising robustness.
The motor delivers a Continuous Torque at Standstill of 0.33 Nm and sustains a nominal speed of 10000 min⁻¹, offering precise dynamic response across its Motor Size 025 frame. A 1.0 Nm Holding Brake Torque blocking brake secures loads during power interruptions, while the Resolver feedback system provides accurate position information down to microstep resolution. The Centering Diameter of 40 mm and Standard (without side B shaft end) configuration streamline mechanical integration, and the left-hand Connection Direction minimizes cable strain in confined spaces.
Engineers will appreciate seamless integration into OEM drives thanks to the standardized form-factor and digital feedback loop, accelerating machine commissioning. The built-in blocking brake and reliable housing construction translate to reduced maintenance and higher uptime in industrial environments. Together, these features make the MDD025A-N-100-N2G-040FL1 an ideal choice for precision positioning tasks in automation, robotics, and packaging machinery.

Frequently Asked Questions
How does the nominal speed of 10 000 min⁻¹ (rpm) influence thermal and bearing design in continuous operation?
Higher speeds increase frictional and windage losses, so bearings and housing must dissipate heat effectively; lubrication quality and bearing preload become critical. Also, cooling or duty cycle should be planned so motor doesn’t overheat in long high-speed runs.
How does having a “plain shaft” and no shaft seal affect maintenance and environment suitability?
Without a shaft seal there is less protection against ingress of dust, moisture or contaminants, so in dusty or humid environments additional protective measures are needed. On the plus side, omission of the seal reduces friction, cost, and parts subject to wear.
In what way does the “1.0 Nm blocking (holding) brake” impact safety and positioning, especially during power loss?
The blocking brake secures the load when power is off or in emergency stop, preventing unintentional motion or drift; useful for vertical axes or overhead loads. But one must ensure brake actuation time, life, and friction-torque consistency are suitable for the application’s cycle frequency.
What integration challenges might arise from the “Connector style interface” and “Left-hand connection direction”?
Connector style helps simplify commissioning and wiring, but requires correct orientation and strain‐relief; left-hand routing may conflict with existing cable trays or pose cable bend issues in tight layouts. Ensuring connectors are accessible for service without disassembly is also important.
How does the 40 mm centering diameter affect mechanical coupling and alignment?
A centering diameter of 40 mm provides a stiff, well-defined interface reducing misalignment between motor and load; helps lower vibration and wear especially in high-speed operation. However, mating components must match this diameter precisely; sleeves or adapters may add complexity and tolerance stack-up.
