Body
I notice the design of the motor is much like a ceiling fan motor ..you can
get them for almost nothing at a scrap yard there so common .something
cheap to tinker with . and we need more information on his work even a
block understanding or base principal would give some direction .I finely
got my ten coil mulity strand going and turned a profit from it got two
golf cart batteries and they were dead with sulfation read 12 volts but
only lasted 1/2 hour till inverters tuned off but now the run all night
it's desufating and charging .now I need a battery charge meter from Napa
.got them for 20 bucks each looks like I'm going for a 12 battery system
to parrell my solar panel system a Bedini plus the four battery system
.that would be around 160 for dead golf cart batteries an 80 % savings
.it's to soon to really tell yet . I might actually be able to get a
refrigerator running full time on it 🙌.
