Single phase to three phase equivalent

[rabler]

Hate to be the bearer of bad news, but I see a problem there in matching the VFD and motor. Your motor is rated for 400V. The VFD output is rated for 0-Input V. That likely means 0-230 since the input is 230. You won't be able to get full power out of that motor, closer to about 1/2 power.

I don't like that news. I will have to speak to my brother inlaw who put this together for me. He is an electronic engineer with his own business that builds inverters and transformers. I will mention this to him, maybe he made a mistake or didn't pick it up.

I don't know much of this stuff

Ok, he said he re-configured the motor to delta and now it is 3phase 230V. Does that make sense to you? I must add that my brother inlaw knows his stuff. I personally think he is a genius. He said something like you can't re-configure all motors but apparently you can with the motors in South Africa........or something like that. Like I said, this isn't my forté.

Electrical isn't my job or anything, but that at least somewhat checks out. The motor itself doesn't say it is a dual-voltage motor, but I don't know of any reason why switching a star to a delta layout wouldn't 1/2 the run-voltage. It DOES look like you'll be over-volting it slightly (unless that 400v is wishy-washy ).

I don't think it as anything to do with South Africa, but perhaps there is some sort of regulation or something that caused that.

And that's why I said..."or something like that". Electrics confuse me a bit. The little I know, I still check with someone who does.
