Re: [CAD_CAM_EDM_DRO] AC Servo Motors???

John

Don't know of any cheap drives for those motors but if I was you, I would
grab them all, stick them up on ebay and buy whatever type of drive and
motors you want with the cash you get for them. With a worldwide audience
looking, someone is probably looking for exactly that motor. I never turn
down free stuff, and have hauled home a lot heavier stuff than those.
