I'm new to this, but want to do a DIY project first so I can learn from the bottom up. I've found a Treadmill motor, but it does not give any rpm's per watt or anything. All I have is 17.2 amp @ 7099 rpm- 25C-class B, 2.5hp @ 130 VDC, from what I can detect estimating by attaching a Volt meter to the unit is that at (very roughly) 60 rpm I'm getting 1 volt. Will this motor work? I've tried looking up the motor on several websites for the treadmill but no one gives a volt rating. Any help appreciated, or any idea's how to maybe come up with a better estimate.... mark
Mark, It is no good. The rpm's required to generate 12-14 volts, which are the volts necessary to charge a 12 volt battery bank, would need at least 20 mph wind. When the wind is between 0 and 20 mph you would get no charge to your battery. And since the wind is rarely above 20 mph, your mill would rarely be charging your battery.
Darn, I'll just have to keep looking. Motors are hard to find these days. (The free one's) I could gear it up some how, maybe. m
