kiss a VFD a good bye . now you can run 3 phase motor on your normal 240v main
I found this to be very interesting.
love to give it a try.

How to shorten motor life
Greetings Peter,
I'd consider this a quick and dirty way to get your motor running.
Given that the recommendations for good motor life involve things like phase currents all in balance to within 3% or better, minimum of harmonics etc, I would not expect a motor so wired to have a long life expectancy.
As others have said the vibration levels would be nothing to write home about, and one of the reasons for running three phase motors is the reduced vibration so a bit self defeating??
I'd like to know what the motor start currents are. Single phase motors can have quite high starting currents. I looked at replacing a 4kW three phase motor with single phase. The starting current was quoted at 129 amps. I'd also be interested in the starting performance on heavy static loads like a compressor.
VFD's are pretty cheap these days. Why would you give up their advantages for a jury rigged system?
