MDD025B-N-100-N2G-040FB0
MDD Synchronous Motors
The MDD025B-N-100-N2G-040FB0 is a motor for digital drive controllers manufactured by Bosch Rexroth Indramat. Part of the MDD Synchronous Motors series, it features resolver feedback and delivers 0.60 Nm continuous torque at standstill. With a nominal speed of 10000 min⁻¹, a 40 mm centering diameter, side B connector connection, plain shaft and housing, it omits a holding brake and shaft seal for streamlined performance.

Frequently Asked Questions
What should I account for when the motor has no shaft seal?
Without a shaft seal, the motor shouldn’t be exposed to coolant spray, oil mist, or dust ingress—use shields, bellows, or an external seal at the machine interface. Bosch Rexroth project-planning guidance covers environmental protection and integration practices.
How does a 40 mm centering (pilot) diameter affect mounting precision?
The pilot locates the motor concentrically to the machine, so match the mating bore and tolerances to minimize runout and coupling misalignment. Follow the series project-planning rules for flange fits and concentricity to avoid bearing loads.
What are the risks of running without a holding brake on vertical or safety-critical axes?
Axes subject to gravity or back-driving need a mechanical brake, counterbalance, or safe torque-off strategy; the drive alone doesn’t provide power-off holding. Size any external brake based on static load and safety factor, and validate stop distances.
For the Bosch Rexroth Indramat MDD025B-N-100-N2G-040FB0, which drives are commonly compatible?
MDD synchronous motors are used with Indramat digital servo drives such as DDS and DKS; check your exact feedback and connector options before pairing. This variant’s resolver feedback aligns with those drive families’ supported encoder types.
What coupling choices suit a plain (smooth) shaft at high speed?
Use precision, backlash-free couplings (e.g., clamp or collet style) rated for the speed and misalignment, and balance them to reduce vibration. Follow the series integration guide for allowable radial/axial loads and alignment tolerances.
