I've been looking at these two ETEK motors in my garage and I have a scooter I want to put them on.. but the thing which stopped me so far is a motor mount. Okay it's just a metal plate and you drill some holes, big deal. But I'm thinking there has to be premade motor mounts available somewhere. And I recently learned that there's a standard motor faceplate design (named: "NEMA C" IIRC) ...
One thing about a standard is it should mean there are companies making widgets that match that standard.
However I did some googling and came up with motors that have a NEMA C faceplate, but not motor mounts.
