OK sounds good.

I have been working on the regenerative aspects of my project for a long time now. When I talk about it people assume that I mean regenerative brakeing, or an off the shelf device. I came up with a way to reclaim the reverse electromagnetic field in the motor also some noise from the brushes and excess forward current when under load or stalled and inbetween pulses. The collected energy is stored in capacitors and consumed by the battery or motor again.

I think I might have posted some of this before but, this has been my baby. I am not as good with the mechanical side of it all and I would appreciate some advise with reguard to mounting the flywheel to the motor shaft. I have found some hardware to fit the keyed 7/8 shaft with a flange but should this be a pressed fitting that grips the shaft tight?

I started with small toy motors to see if I was sane. I got 26% more run time matching the same speed. When the motor finally quit after 26 hours running as fast as it could go, it would slow way down and then suddenly start up again at full speed for a few seconds. It would do this 3 times and then stop as if a switch had been turned off. I allowed the small AA battery to rest assuming that it would run the toy motor again after an hour or so. It did not. The circuit had emptied the battery totally. Chargeing capacitors can do that I discovered.
Then I used an Etek motor and got better results. I won't say how much better until the next motor and all is in the car and I can say, OK here it is good or bad.
I just discovered the benefits of using IGBT modules for power output stages which should make it smaller in the end. The 2nd prototype is in a box that measures approx 14 x 19 inches by 6 inches high.
I do share. If any one understands electronics and pulse width modulated motor speed controls you can ask me for the schematic. Its is crazy different but it works at least as much as it runs my big motor for 52.5 hours on a small car battery. I now have a provisonal patent so I am free to let you all have a look. I am extremly determined to find new and better ways to do things. Please do not hate me for my passion.
