Re: [CAD_CAM_EDM_DRO] Captain Nema Nemo

Someone may have already mentioned this, but 3 phase motors are relatively
inexpensive. If the current one doesn't work, see if you can get him to come
down on the price some, and puchase yourself a VFD and a new 3phase motor in
the voltage that you prefer.

Good luck with it!
