Frequently Asked Questions

What is the significance of specifying “MDD021B-N-100-N2K-032MA0” by Bosch Rexroth for matching with a drive controller?

This precise product code ensures compatibility in terms of encoder feedback (absolute + resolver), connector type, and physical dimensions—critical to avoid mis-matching of motor feedback wiring or drive‐parameter lookup. Using the correct model ensures the drive’s firmware expects the motor’s inertia, torque constant, and feedback signals, which affect tuning and stability.

How does a nominal speed of 10,000 min⁻¹ affect selection of power supply and cooling?

Running at 10,000 rpm increases electrical frequency and mechanical stress, which demand adequate winding insulation, bearings, and drive output capability. Heat buildup is greater at high speed, so proper thermal management—via ambient airflow, heat sinking, or even forced cooling—is needed to maintain reliability.

How does the motor’s keyway shaft and lack of shaft seal impact mechanical load handling and environment use?

A keyway allows reliable torque transmission and form-fit coupling, making it suitable for attaching gears, pulleys or hubs without slip; however, lack of shaft seal means ingress of dust, liquids or particulates could reach the bearings or shaft interface, reducing lifespan unless environment is controlled or extra sealing added.

What does “center diameter 32 mm and standard balancing” imply for dynamic performance and vibration?

A 32 mm centering diameter helps ensure rigid mounting and alignment, reducing wobble; standard balancing means the rotor has been balanced well enough for typical servo drive applications but may still cause vibration at high rpm or under heavy radial/axial loads. For high precision or high speed, enhanced balancing or vibration monitoring may be needed.

In B2B industrial settings (robotics, printing, semiconductor), what mounting or environmental considerations are essential for this motor?

Precise alignment of the centering diameter and mounting flange is crucial to avoid misalignment causing run-out or bearing wear; also environment control (temperature, humidity, particulates) and ensuring compatible drive controllers for the resolver/encoder signals are needed to maintain performance and avoid costly downtime.
