It is a civic IMA, He probably assumed it was an insight after walking around my place and seeing all the insights.
Pretty much the same.
The bottom line is that he has no feedback, and is driving it with a simple square wave. He had it sitting in the back of his car, and ran up the 3 phase motor nicely.
No need to deal with the complexity of the MCM, just need 3 squarewaves with the proper phase, and a way to change the run frequency.
A look at his schematic, and you can see that his clock is just a LM555 timer.
I have to wonder if one of the hobby 3 phase speed controllers used for the 3 phase model motors would drive the inverter?
