Re: [CAD_CAM_EDM_DRO] Re: DC brush type motor control

Theree are one or more nice toroids in PC powersupplys. Find some failed
ones and remove the toroids.

Remove the wire and rewind with wire suitable for your power requirements.

I did this when I updated my BP with a VFD. Scoped the power afterwards
and it is clean.

Final wireing will be in flexable metal conduit.
