vertical axis wind turbine Frequently Asked Questions
Windmill with car alternator?
I'm trying to build a windmill (vertical axis wind turbine to be specific) and I was looking at this car alternator
http://www.amazon.com/Bosch-AL534X-Remanufactured-Alternator/dp/B000BZLFR6/ref=sr_1_2?s=automotive&ie=UTF8&qid=1286235099&sr=1-2
I've been having a terrible time finding info on what kinds of motors/generators/alternators will work for which situations, so any input is good to me.
There a probably several alternators that would work for a more simple design.
There are few things to keep in mind if you plan to use an automotive alternator however.
a. For simplicity, try to find a unit that utilizes a single wire connection.
b. Choose pulley/drive combinations that will keep the unit at a moderate rpm for best
cooling and power output. Make sure your mounting method doesn't restrict air flow
across and through the alternator.
c. You need to understand all of the basics about how alternators work to make your project a
success.
You can learn quite a bit here:
http://www.alternatorparts.com/understanding_alternators.htm
d. Your project will likely involve working with several hazards, namely
1. Strong mechanical forces
2. Significant amounts of electrical energy
3. Hazardous chemicals (lead/acid batteries)
4. Elevated work locations
Plan each section of your project and give careful thought to the safety aspects.
Learning by doing is great, but not if it comes at the expense of your health or well being.
If you are not sure about any part of your project stop, educate yourself, and/or seek assistance.
Building a generator?
I'm looking into building a vertical axis wind turbine to generate power for lights in a greenhouse, but I can't find much about building the actual alternator part to turn the rotation into electricity. If I have two disks, one with a series of copper wire coils and another with corresponding magnets, and the one with magnets is spinning over the copper coils via wind power, how do I harvest the power generated from the process? How should the magnets be oriented? What exactly do you call this kind of generator also, I feel as though if I had a name for it, I'd be able to find more info... Thanks in advance
And please don't tell me to go buy a motor or alternator...
I ma not sure why you have settled on a disc architechture for your generator but if you would like to get a lot of insight into this arena go to
http://www.phys.unsw.edu.au/hsc/hsc/electric_motors5.html
This discusse a lot of the theory behind a printed circuit motor which is used in high frequency response servomechanisms for low rotary inertia. (you I am sure have been told several times that "a motor is a generator is a motor". It may give you the infoo that you need.
It shows how to arrange discs of magnets on either side of the printed circuit.
