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?

His video clearly shows and states 18 amps regen. 18a x 156v= 2800 watts!

2800w at 3000rpm is 6.5ftlbs.

Hard to say the exact torque being applied, but in 3rd gear it would be about 3:1 times the rear-end at about 3.5:1, so the torque applied is multiplied about 10X!

So that is ~65ft lbs.

Here in Montana, just tapping the brakes can cause sliding, so 65ftlbs would definately cause it under slick conditions.
