Great explanation. I consider the inertia ratio to be the single most important calculation when applying servos. If a motor/drive package has enough wattage to do the job at hand, and the inertia is properly matched, the system will normally work well with reasonable attention given to the mechanical details.
Maximum power transfer is often overlooked as a benefit of inertia matching.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
