Evening All Been reading lots of threads regarding the suggested power output from using a DC motor as a wind genny. I am interested as I am lurking on several motors myself after several failed attempts with different motors (stepper motor with nothing coming out and an old golf buggy one that barely gets up to .5v!) 
So as a quick and easy to use tool I put the attached spreadsheet together. Just fill out the rpm and voltage and you should be able to get a quick guide to what voltage you can get out at various wind speeds. Just thought somebody may find it useful

I played with it.. it seemed okay. What would be more useful, if possible, is to make it show you the RPM required to produce the correct voltage to charge a 12V battery (I think that figure is around 15 to 16 volts, right?) |

Yeah I liked it. Nice and simple. I put in the approx figures for those 24v scoota motors, that is 24v at 2500 rpm. It gave me 6 volts output at just over 600rpm. From meory, that was the result I got with the little windmill I made based on an scoota motor. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |
