What trade-offs come from “standard balancing” for a rotor in high-speed applications?

Standard balancing is adequate for many duties, but for very high-speed or low-vibration systems, you may demand higher balance class (e.g. G2.5 or better) to reduce bearing loads and resonance.

In what cases is the centering diameter of 130 mm (flange interface) critical for integration?

The 130 mm centering diameter defines how the motor mates to machine frames or gearboxes; precise alignment and bearing preload depend on this interface to avoid misalignment loads.

What installation or alignment tolerances matter for the side-B connector orientation?

Since the connector is on side B, cable routing must avoid interference; also maintain angular and radial alignment to avoid stress on the connector pins during assembly.

How is commutation performance affected if rotor inertia or load inertia is much higher than expected?

A mismatch between motor and load inertia reduces servo bandwidth and can lead to oscillation or slower settling, so keep the total reflected inertia reasonably matched (e.g. ≤ 10× motor’s rotor inertia).

How would you refer to this motor in a technical support query using its exact model and manufacturer?

Use “Bosch Rexroth MDD090C-N-030-N2L-130PB1” when requesting firmware, support, or spares to ensure precise identification.
