I've recently began to dabble with PV and since we do tend to get some good breezes (Harnett County NC)I've decided to try my luck at wind turbine energy as well. I've been reading about how people turn a treadmill motor into a generator. My PV is the HF 45 watt set. It does a great job of providing lights in my barn (it comes with 2 12vdc lights).

I have an HF 2000/4000w inverter hanging off it and when the batteries are fully charged I run my drill, recip-saw or circ-saw etc. But certain days with lack of sun the panels barely push 11.8v.

Yet the wind is blowing my neighbors lawn decor windmill full speed. 1 ) I've run up on a Roadmaster Corp Vitamaster 500 treadmill for $20.

Does anyone know what sort of motor it would have and would it be suitable for said needs? I've searched the web for any info on them but can't seem to find any manuals or info. 2) If the above motor wouldn't be suitable than I've considered trying to rebuild a ceiling fan into an alternator. Anyone have any luck with one?] TIA Paul ads.@wizardanswers.com 17:26. Depending on the size of your propeller, you could go to the junk yard and get an alternator from a car. If you are at all resourceful, you can probably come up with an alternator without spending any dollars, there are literally millions around.

I don't mean steal it, someone around you is junking a car. How big is your prop?

How about a Savonius rotor? Keeps everything near ground, easy to work on. Here are a few examples, Give us an idea of what power you plan on generating, is a 1000 watts max enough?

A 100 amp alternator will do that. Find some average wind speed maps for your area, get some info to start working with. Mikek Clare 21:38.

Not only that, unless modified with strong field magnets, they require a hefty excitation current.

In general, unmodified auto alternators are useless for home/hobby-sized wind power. Connected to a suitable small engine though, they can make a great emergency battery charger. Just checked in to look at replies.

Still cookin'. Some of the 'home alternator' motors are designed with two magnet rotors circling the stator. Double the power. Then as mentioned pulley ratio power ( or gear ). Not a car alt/gen. But they also talk 6 - 10 foot blades. I've decided to go with(3)26' blades to start.

I'm quite the newbie at this stuff and I need to suppliment my solar panels on cloudy but windy spells. My use so far ( [3] 35ah 12 volt battery bank- 2k-4k inverter ) is to provide lights and some 110 power in my barn. Nothing to do with departing the grid at the house. I did the PVC blades. From stuff I've read lately the treadmill motors are low rev as a generator and good for windmill/turbine. Plus it's DC. Ready to hit the batteries.

I'd like to try one and if it helps suppliment the batteries then I'll go for more. Still in learning. I just recently learned what a diode is. And how/where it's used. Havin' fun in the mean time. Thanks again to all who've posted. Paul Clare 21:16.
