NOT perpetual motion, altenator regen?

Alright now bear with me guys, it accured to me that since I'm utilizing the 9" ADC double shaft motor,and I'm not using the double shaft end for any purpose, why not use pullys and belts to drive an altenator ( free wheeling most of the time), coupled with switches so that when I hit the brakes it turns on the altenator, slows down the vehicle and acts as a form of regeneration. I've already been told that my series DC motor isn't suitable or designed for regen and I'm mostly interested in the range of my vehicle. I can imagine that even in the freewheeling state said altenator would decrease my range just by turning the shaft, but what of the regen. possibilities could they significantly increase my range? I do live in a little bit of a hilly regon as a matter of fact if i go one way from my house I immeadiatly asscend a 300-400ft hill, I would love to be able to recapture some of that expended energy on the other side of the hill with regen......... comments?

You don't want to use permanent magnet field as you could vary the regen by adjusting the field. You want to get a large truck alternator and rewind it for your pack voltage (bit higher). You want to mount an electric clutch on the front of the motor, you could use an AC clutch. Press a button, engages the clutch, drives the alternator. The braking from this set up can be quite strong. I will look up a link for you. This fellow did exactly what you want. I kept it as I was going to do this. I did mount the clutch...

Here u go.... http://www.waynesev.com/

Just look up the Regen Braking link on the left side....

He's getting about 10 amps at pack voltage. I can barely feel 10 amps of regen in my car, and it won't give you any noticeable range. For all the work he put in he basically ended up with nothing as far as I can tell.
I actually spoke to Wayne about his little regen system a while back. He was quite happy with it and said that the braking was quite noticeable. I think the braking is the bigger asset for most ppl. He said he had to be careful in the winter as he could easily skid his back wheels. :eek:

ya, it's true.... the numbers are low for any significant braking...although I wonder if he is capturing his peak output. He does mention popping a 15 amp breaker a lot in the beginning.
Wayne's words....
"I was surprised at the braking effect of the Regeneration System. The braking sensation is very strong, giving a strong addition to the power brakes of the S10".It was definitely a lot of work...but very kewl what he did...:)
