Hello All,
I’m having issues setting up a 3 phase converter. I have a 20 hp motor I’m using for the idler. I bought a converter self wire kit off eBay that came with schematics. Got everything wired up to my 220 panel and the idler came on and ran fine. Tried to turn on a machine to test it and it wouldn’t start, the motor just hums. It was late so I called it a day. The next morning I had a thought that the motor was wired for 440 not 220. Well it was, I rewired for 220 and now when I power the converter on it only gets up to about half speed. When it was wired for 440 I caked the output and T1 to ground was right around 120, T2 to ground was 120 as well. T3 to ground was reading 440v. Checked the incoming and L1 to ground was 120 L2 the same. L3 which has nothing connected is reading 440. I’m at a loss. Any info or help is greatly appreciated. Thanks
