Some may remember my postings from September about my small motor conversion, where I was having trouble with my chain drive and had decided to direct drive with a 5' prop hoping it would compensate for the 20% rpm increase from the 6' prop with the chain drive. It did work but would stall at about 170 watts, so I decided to reuse my 6' prop after cutting down the root as much as I dared to lighten it up. I found that my cut-in speed was way too high and would only get output in small storms, so I tried it into 6 volts and find that it does very well in light winds, in fact over the past two weeks, have never seen it below 2 amps and normally at 15 amps in a 12 mph wind. I have seen 22 amps but no idea at what point it will stall, (or if it will), for my winds have been fairly light up to this point. But I am very satisfied with the output in these low winds. Very low rpm on the prop and very silent. Now for my
If I want to rewind this for 12 volt, leaving everything the same, if I increase my windings from their present 12 per coil to 24 per coil, but at half the size wire, what effect will this have on prop speed and output because of the higher resistence (half the diameter wire, twice as long)? Any thoughts would be greatly appreciated.
