Does anyone have info regarding the Huanyang vfds and if they have improved? Over at the Practical Machinist forum which gets into some pretty detailed and complicated electrics, the Huanyang vfds are prohibited from discussions because the moderators believe them to be so poorly built. No first hand knowledge, just wondering. Dave
I thinking a diagram would be no help to you not every thing can be fixed with a screw driver. Dave may like this

Id post for Huynang vfd support on cnc zone and other diy cnc sites. There are far more cnc machines running chinese vfds than any old ww machines for sure and they are doing darn more sophisticated setups with them. Modbus controls and plc interactions and variable speed ramping models. This is not drive grand dads clausing or aircraft carrier sized jointer to show your poker buddies with only the buttons on the vfd face or maybe a switch lol. They can hate all they want but guarentee those Huynang powered spindles on the cnc machines that are being used are clocking 50x more hours than on the owwm those guys are collecting.
Glad its my shop I am responsible for - I only have to make me happy.
Those drives are garbage even for programming a few bucks more you get some really good stuff . Most modern drives will go up to 600 Hrz and you can buy the spindles from China for dirt cheap . Controls are not so much on the VFD on CNC as they are on the table servos . They all come with plc . A dumb elevator runs on PLC

My apologies, I wasn't advocating the use of 15Hp on your proposed tool stable. I was just curious about someone's comment and looked to see what was largest horsepower motor offered in 230V/1ph.
(I forget sometimes that my schitzo thought processes are not immediately apparent to the outside world. Welcome to the Twilight Zoonnn .... er, SHOP. Yeah. Twilight SHOP.)
I haven't gotten an exact quote from the power company, but today they told me that it may be possible to get 3-phase, but it will likely be VERY expensive, so likely a no-go.
BTW, would it matter to the Felder machines if it was 208V 3-phase or 240V 3-phase? It appears that Duke Energy would only provide 208V 3-phase here (if I am reading their information correctly).

I gotta wonder - at what point would it be cheaper to buy a used (or even new) 3-phase natural gas or propane generator and just run that when you are in your shop?
You guys are all laser-focused on treating this as an electrical-only situation when there are other ways to solve it.
That is an utterly fascinating idea, but the neighbors would likely get pretty upset at the noise of the generator. I'm going to very great lengths to prevent noise outside the workshop.
The little stream on the properly could potentially power a 0.01HP motor. On occasion.
