I don't see why that did not work, is it when you switched the machine on? or just the transformer?
Actually those motors are not that big, The AC motors usually have 240v connections that you can drop them down to 240, the only thing is you would have to check wire size and overloads, but for those sizes it should only be overloads to change.
The control and servo's might pose a problem but they will most certainly be 120v or 240v, so it should not be a big deal, even if you have to fit a control transformer.
I would think you should be able to convert with minimal fuss, as long as the motors are changeable.
