MDD025B-N-100-N2G-040FA0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD025B-N-100-N2G-040FA0 is a motor for digital drive controllers in the MDD Synchronous Motors series. It provides a continuous torque at standstill of 0.60 Nm at 10000 min⁻¹, with a 40 mm centering diameter and resolver feedback. A plain shaft and side A connector in a standard housing complete the design.

Frequently Asked Questions
How does resolver feedback on MDD motors affect commissioning and precision?
Resolver feedback provides robust commutation and ~16,384 counts/rev effective resolution; drives read motor-stored parameters at power-up for safe operation. Homing is required after power loss unless the variant includes the integrated absolute pulse encoder.
Does the lack of a holding brake limit vertical-axis use?
Without a blocking brake the axis won’t hold at power-off; use a mechanical brake on the load or specify an MDD variant “with blocking brake” if needed. Drive-controlled brakes are supported in the MDD system architecture.
What drive families are typically compatible with MDD025B-class motors?
MDD series motors are designed to operate with DDS and DKS digital servo drives sharing a common DC bus supply. This modular pairing is standard in Rexroth Indramat architectures for multi-axis systems.
How does a plain shaft influence coupling choice at 10,000 min⁻¹?
Use a zero-backlash, balanced coupling rated for 10k rpm; avoid undue radial load to protect bearings. Pilot alignment plus proper coupling selection minimizes vibration and preserves servo bandwidth.
What’s the practical meaning of “Side A” connection direction during installation?
“Side A/Side B” are standardized orientations on MDD motors to plan cable exits and bend radii; angle or straight feedback connectors are available depending on space. Correct side labeling prevents cable strain and simplifies panel layout.
