I've got three ametek motors that all have the 30 volt sticker on them......and only one is probably a 30 volt...another is probably one of those 38 volt motors....because it's only good for a trickle.....even in high winds..there's just no amperage there....and the third is a 5" motor that definately not a 30 volt....
Some ameteks are an awful lot better than others......
