... engine and motor has never been synonymous. The phrase "electric engine" should cause physical discomfort to anyone hearing it. But feel free to call it all a motor - that's a clean superset of all the things an average person would use either term for[0], and most languages don't even have the "engine" term anyway, indeed using motor for the whole lot. [1]: For other uses like "train engine", there are more distinct alternatives such as "locomotive".
