I think that diagram is accurate but has alot more details than I am familiar with. There are a bunch of capacitors with the RPC. I had to pause for about a week to get a cabinet job done but I will be back on it soon. I will check the circuit connection from the contactor to the motor. I will...

So it purrs like a kitten at my friend's shop. It has 3 phase from the transformer. The voltages there are all 115 each line to ground. 220 between each lines. At my shop 1 of the lines has 225 to ground and 115 on the other 2. I just realized that I haven't checked the voltage at the motor in...

Thanks Waross. I understand alot of what you are saying but not all. I think you are saying that the motor my not be the problem. I should take it to a friends shop that has 3 phase power and try it there.

Winding resistance to ground is mega. The tag on the motor says 34 A. I can't detect any resistance at all on the line. Maybe the tester is not that great.

I check the resistance between each line at the motor. I have 0 ohms at all 3 tests. 140 A when I try to start it. I think not good.

The motor does spinning free. It has a little drag but it is not locked up. I just put an new bearing in it. I always start the converter before the motor. LOL on the ohm's law thing.

This was inside the box of the converterhttps://files.engineering.com/getfile.aspx?folder=eda77c61-fec7-4fbb-9fd6-49c0a4840d79&file=Converter_notes.jpg

I guess it went through. Here is the converter.https://files.engineering.com/getfile.aspx?folder=1a4379c0-f6c4-4f01-8aa5-d4681ae89806&file=Phase_converter.jpg

I am trying to upload pics of the ID plates on the motor and the phase converter. I've not used this forum before. I must be doing something wrong.https://files.engineering.com/getfile.aspx?folder=96ef0c2f-6b89-491b-a7bc-2818bdb3c2c5&file=Motor.jpg

che12345. As I typed the term 3 phase converter I didn't think it was the right term but I didn't know the correct one. I takes the single phase and manufactures a 3rd leg. I don't know if that is a VFD or not. It doesn't change the frequency. It looks like an electric motor and it spins when...

I have a 10 hp motor and when I turn it on it just growls and won't turn. I have a 3 phase converter. I measure the voltage on line 1 to line 2 @ 260V. Line 1 to line 3 @ 245V and line 2 to line 3 @ 251. When I measure each line to ground I get line 1 @ 124, line 2 @ 225 and line 3 @ 124. The...
