Lately I've seen some of the cheap Chinese motor mfrs selling "220V" and "440V" motors. I think this is due either to their own ignorance, or possibly a cleaver marketing ploy to get business from people who read 220V on old motors and not know that this is no longer a valid voltage rating but that 208-240V is OK for them, search around for new motors at those ratings, and only find those cheap Chinese suppliers.
