Magnet FAQ

[TheCasualTraveler]

This is my idea of what I would put under magnets. I started with magnets because the FAQs section directs you to 3 links, the first which seems to be a dead link, the second about overunity and the third gives in depth faqs but not what newcomers usually ask. It is purposly short to get the newcomer the basic facts they need without boring or overwhelming them. Please let me know what BASIC information I have left out or gotten wrong. The next FAQ would be "Magnet Rotors" and build on this one.

Magnets - What will I need as far as magnets go? For a serious power-producing turbine you will do best to go with large Neodymium type magnets. These are not common magnets but very strong magnets that come in different grades. Unless you want to learn all the math and theory behind building a turbine you don't need to know much more than to use large Neodymium magnets. You can buy them here****The most common grade is *** The most common number of magnets used is between 8 and 24. The most common size used is 1 inch by 2 inch by half an inch. Other common sizes are 1 inch to 2 inch round discs. You can also find them wedge shaped. If you use magnets smaller than this, unless you use a LOT of them, you will NOT produce much usable power. Decide on all size aspects of your turbine BEFORE you buy your magnets.

OK, maybe the users can add or clarify as needed.

Oh goodness im confused.

Yes, thats the idea. That was a start now those that care to contribute can add and/or edit what this FAQ should be. Or poke fun if that's their contribution.

Number of magnets also relates to number of coils and number of phases. 3 phase output is good. This requires 4 magnets per 3 coils to generate 3 phase, or multiples thereof. Like 8 magnets and 6 coils. Or 12 magnets and 9 coils.

I'm not poking fun Andy,

 I just miss the old days where everybody experimented with stuff.Now it seems everyone who has a high electric bill wants to build a turbine or whatever tomorrow.

 This addiction needs to be treated has a fun hobby.

Maybe split the site Otherpower 1 for built turbines and Otherpower 2 for beginners and theorist until they build.A thought.

 There are some uses for large ceramic's to.

I/E_low cost medium power gennies 4 to 500 watts.

i think you have the right idea...but if i was a newbie..more than one option would confuse me.....2" magnets are a pretty safe be to build a decent turbine with little cash flow...i would recommend you follow womeons proven turbine specs before changing anything...i have some nice 200 turn stators you can have because i thought bigger was better when i started out...then i found out about resistance..now those stators are just educational tools..  take care..pickster

I agree, you should definitely specify the magnet to coils ratio.

Also, the magnet shape will determine coil shape. Coil shape can have influence over power output. Magnets care should be an issue as well (rust, max. temps recommended). Types of magnet coating and the recommended adhesives/resins/paints.

Everyone should experiment but if one can avoid mistakes already made by others, they should be warned. It may be too hard to sum up all the experiences in one foolproof guide but general info (and common sense) should be enough.

    1. The VERY FIRST fact that a NEWBY should realize, is that a wind

generator is NOT a magic solution to filling your pockets with cash by

producing energy that is way cheaper than the grid. IT DON'T Happen. Your

cost for the construction will far exceed any savings that you will ever

realize.

     2. Wind generators are dangereous. Electricity can kill. Falling towers

can kill. Flying broken blades can kill. Batteries can explode and you can

easily create an unsafe fire situation.

     3. You are wasting your time if there isn't enough wind in your area.

     4. Your comunity probably has regulations that could prevent you from

raising a tower.

     5. Grid ties require an inspection from the hydro company.

     6. Your fire insurance will be affected. Maybe cancelled or claims

disallowed.

     BUT....

These above facts do not stop us because we are builders, tinkers, explorers,

inventors, problem solvers and look foward to the challenges. We will

eventually make this a better world.........

I wrote this last year:

Whatever you write, you should have clear and simple pictures to illustrate what you're talking about.  

[vawtsup]

I thought this forum was to share info on energy production to everyone. Not just the hobbyists and theorists, but those who see an actual need for energy production by individuals. It seems some think it's a circle j*rk.

Maybe it's time to take it to the next level.

vawt;

What the h3ll does this have to do with a Magnet FAQ?

Nothing.

Nobody is twisting your arm to be here.

Don't let the door hit you where the Lord split you on the way out.

TomW, it looks to me like vawtsup meant to reply to vawtman. In that context vawtsup's comment makes some sense. :/

take it easy

Hi: The amps listed in that wire gauge table are more reflective of DC current than AC single phase current, IE #14 is "used" in houses as rated for 15 amp service, #12 20 amps etc.. And you can run an 1800 watt blow dryer continuously and the #14 wire will just barely be warm... Each phase in a gen is seeing only a single wave form, I believe, therefore more representative of AC current loads for wire size.

 "Each phase in a gen is seeing only a single wave form, I believe, therefore more representative of AC current loads for wire size."

When conducting each phase in a star connection will have a current flowing through it due to nearly twice (actually 1.73 times) the phase voltage.  Of course, each phase only has current for two thirds of the time.  Also, the presence of a battery and diodes also will lower the current compared to say a short circuit condition.  You really need to run the numbers to get an accurate picture.

[finnsawyer]

Well, the two phases in series does double the resistance, so in a sense I suppose your statement has some validity.  But the end result still depends on what is connected to the alternator.
