If Curtis Manufacturing Co. come up to the market with a AC introductory motor controller for under 1600, how could we not make a controller Kit for the same application at 1/4 of their price with top notch technology?
Paul, have you narrowed down the selection of IGBTs for the controller prototype yet?

I was thinking of these for a higher powered inverter:
PRX CM600HA-24H IGBT Power Modules 1200Volt 600Amp - eBay (item 350264741592 end time Dec-12-09 10:14:45 PST)
They consistently have these available for about this price. That would be $300 just for the igbts. It might be another $300 for everything else. I think it would be pretty high power though. I would rather try this first:
Mitsubishi MG400Q1US41 IGBT Module 400Amp 1200Volt - eBay (item 350264741683 end time Dec-12-09 10:14:58 PST)
As the sum of the 3 currents rotates, it makes a net current. So, if the net current is like 300amp, it's shared between several devices. So maybe it can put out quite a bit higher? I need to understand how the current is shared a little more. I just got the A/D converter working on the dsPIC30F2010, and I still have more to learn about how it all works. hehe.
