Wow Lee, thanks for all the info! It let me know that DC motors aren't as "bad" as I was led to believe.
I am a professional Agile/Lean software development coach. Our motto is "Fail fast and learn". This means it is better to do something wrong and learn what you can from it as quickly as possible than to spend excessive time in planning for a "perfect" solution and end up with nothing but documents. I think of my prototype car as a "EV minibike" or "EV gocart" that someone suggested as a starter project for learning. My "EV gocart" just happens to be a lot bigger. "DC is not flashy and high-tech enough for an expensive luxury sports car. You want cutting-edge style, you want flash and glamor; you want to make a statement." Exactly why my production car will be AC and have regenerative braking. The prototype will not have either of these because they provide minimal increase in utility (real value to me) relative to the significant increase in cost and complexity. The goals for my "oversize EV gocart" are: 1) Make passes down a dragstrip and be quicker than a stock Corvette (as good or better than a "performance ICE"). 2) Be able to provide "short test rides" to people at various events and shows (let others experience EV acceleration. Charging intermittently is acceptable). 3) Be able to drive indoors with no ventilation (not practical with an ICE). 4) Be able for me to drive back and forth to work (12.6 miles each way. Allows me to claim "daily driver" and gain daily exposure, free advertising, on the road). Obviously it would be great to exceed these but if I can meet all of these I will consider my prototype car a success. -------------- next part -------------- An HTML attachment was scrubbed...
