WOW, what a thread. I finally got through all 306 pages, reading 5-10 pages at a time, until my old eyes crossed. I know nothing about electronics, but, can hold my own with mechanicals. I was hoping the topics would drift just a little bit further off course, and get some discussion going about programming a switched reluctance induction motor, in a lower voltage scenario.

I am of the "jungle with a hand drill" crowd, as Paul said, but, have a few more tools, machines. Down here, in the jungles of Costa Rica, there are hundreds of motorcycles of the 125cc-150cc range. Gasoline hovers around $6.00/gallon. My goal is to produce electric conversions for the locals.

I have built a homemade moto using a hub motor and Chevy Volt 83V battery. Hub motors are too low KV to climb hills very well. Controllers take a beating.

My plan, if ANYONE would be interested, is to try to get a controller working for the E-assist alternator, which can put out over 20 HP at 55v and expected 30+ HP at 72V. I have been in contact with a guy in Spain that has verified these figures. He also wanted to build a controller and I tried to get Lebowski to see about recoding his chip, but, like Paul, he is very busy. These motors are relatively inexpensive for the HP potential.

I know a couple of the posters here also are members of other forums and are very well educated with home built controllers.

If anyone would be interested in working on this, I will gladly start a new thread and supply a motor in the states for whoever would need one to figure out the code.

I also have a step grandson here, who is crazy interested in electronics and no one knows how to build OR repair controllers. I have bought him a started list of stuff so he can get into the electronics and his sister is working on getting into electronics engineering, so, this could be a great future for these two.

Any takers on trying to do this, hopefully ??

Thanks and a great big thanks for all the active members-testers in this thread, especially Paul, things to do and eclipse.
