Seems like if that will work it will help to keep the running bats charged.
Regardless if a pot works to balance the motor could you control the motor's speed? If so then hooking up an AC generator to the motor seems simple to me. Or maybe you could connect the generator directly and leave the motor out?
Just some wild random thoughts.
I am probably going have to wait until next week when I get paid to set up my own system.
I'm really tickled that so many are actually trying something that seems to work and is something I can visualize and follow along with and feel confident I can duplicate. So many threads here are way over my head.
Thanks again guys.
Hi Clueless,

Sure, you can use a 100-watt rheostat. I found some on ebay that are 2 ohms at 100-watts. I'm going to order a couple of these and a couple other values as well... Once you find the right value you may want to replace the rheostat with a fixed resistor though I don't know that it would be necessary...


Thanks for a great circuit! I'll have mine running soon...
