going to have to do something here guys. Have your run of the mill 5hp, 3600rpm compressor that has to be taken to an area with limited power and its going to be an issue on inrush. Already tested the motor under load at 16.5A/235V, and 78A inrush. Its not worth throwing in bigger everything just to cover that 100ms of inrush. I would be happy to reduce this to 2x FLA.
I know it has been discussed here guys, and I am not new to the subject, but lets come up with an idea that makes financial sense. Obviously I can probably find a used motor and VFD to throw at it, but it would exceed the value of the whole compressor.
I would think a means of reducing voltage for a very short time on the main motor winding should calm it down? Obviously a little longer start up but that is a non-issue.
The VFD could be nice to overspeed the compressor just a touch and get a little more, or maybe get creative with the tuning, but honestly, I am mostly looking for a quick, cheap solution for now.
