I agree that their must be some common reference frame but I'm not so sure that the exchange of charge carriers is required for a system to be called a polyphase system. The windings could be separate."In a multiphase system the individual phases are SOMEHOW galvanically related to each other, as one phase is referenced to another or grounded commons. etc." Consequently; when you galvanically isolate the individual phases from each other they seize to be a multiphase system.
