Wow, Thank you!
I've been patiently waiting for my dang isolation transformer before I start the major hardware side. I bought it on Ebay Nov. 10, and it's not here yet.

I now have a Solectria ACgtx20 motor sitting in the living room! The controller and full controller schematics will be making their appearance hopefully soon, but this sucker is going to need a proper, beefy controller. The UMOC controllers it was built with are extremely buggy, and apparently low power compared to what the motor can give.
It does have an encoder on it, but I don't have the pin outs for it yet.
I did a quick glance at the C coding that Microchip has, and I don't know what was scarier, the fact that I these Solectria parts, or that fact that I understood most of the coding. I guess my C++ class this semester has paid off.....  |

Can you take a picture of the encoder? That's perfect.

Well, my encoder is not wanting to come apart, but I have found a supply of pictures that work. ACgtx20 Motor Encoder Repair
I am hoping to be getting the full schematics soon and the Encoder has all grey wires so I have no idea what they do. I got the low down today on how the Solectria controllers function, being MOSFET based makes it quite interesting. It's mainly because the Solectria systems are 144 volts, not really high voltage, but they only used 200 volt fets and bust when the regen activates and the battery pack is full, then ringing pushes the voltage over 230 volts and pop goes the FETs. The newer DMOC controllers has solved that issue. |

It's 11 inches long and have a 10" diameter front plate.
ACgtx20 Specs:
12 KW Nominal
42 KW Peak
70NM torque peak
4,000 RPM Nominal
12,000 RPM peak
It's tiny compared to my FB1-4001A, but basically more powerful than my 96 volt DC setup.
I have no plans to put this in my Civic, but I am planning another EV, probably for 2011 so might as well get started now on the planning. I am thinking of using a 2002 Ford Escape, or Mazda Tribute. I am looking for a small SUV for the wintery drives and planning to save up over the months. I am estimating only $1800 for the EV hardware, excluding the batteries and the actual donor. And it's going to be a 156 volt LiFePO4 system, so I need to do a lot of saving up.
