Latest notes
These notes explain the concepts and applications behind the listings on this site. They are written to be read before an inquiry, not instead of one: a note can teach a buyer how a drive works or how a duty behaves, but only an inquiry can confirm what a listed model means for a specific machine.

How these notes are organised
Every note links back to the listings it explains and forward to the guides and inquiry pages that turn reading into a checkable conversation. If a note and a listing ever appear to disagree, the listing governs the product and the inquiry governs the order, because a note is an explanation and an explanation should never outrank the thing it explains.
