My VAWT (Vertical Axis Wind Turbine) getting ready for an alternator

I am in the process of figuring out what to do for a power source. I've been wanting to build an alternator with magnets and a stator but have failed too many times to go any further. Spending a ton of money on this and getting no where with the exception of this! It really is working well and using the magnets has really reduced the friction I was having in the past.

Yes, it would. That is what I am trying to accomplish but my problem is doing the coil and figuring that out. I need to get the extra cash for the magnets I want to use as well. Any ideas you may have would be appreciated. This thing spins real good in light wind!

[davidrrrd]

were to get these type magnets?

maybe you can use a few small motors like kids power wheels motors as miny generators

this is proof of concept size, i think wider vertion with more blades would have the tork you need to turn something like a pancake motor as a generator.

missouriwindandsolar sells them!

high power at low speed!

instead of 16" across maybe you need 3' radius for enoph tork.

@davidrrrd The magnets were purchased from kjmagnetics (dot) com and run about $17.00 ea. Pretty strong N42 grade NEODYMIUM RING MAGNETS. I do have a larger, wider version I'll be mounting to test as well. Thanks for the info.

Have you thought about using a old school auto alternator ? It all depends on how much power you need to generate. If your just looking to charge 12v batteries I would go that rout. You might be able to go to the salvage and get a auto alternator there cheep. Jut remember if you go to charge 12v batteries to put a voltage regulator on it.

PS: Are you using magnets to levitate this ? It looks like it :) That's AWESOME :)

Great Work

@WulfBand I am using the magnets to levitate the unit. Cuts back a ton on drag.

[kevlauenterprises]

@WulfBand What type of alternator are you referring to? I picked up 7 alternators for a real good deal but spinning any of them does not produce any output voltage. Is there a special brand or yr. trat will work like that and generate power w/o a power source or just from spinning it?

you can not use car alternator without replacing one lot of coils 4 permanet magnets i suggest fisher and paykel motor rewire as per you green dream .com i or dc fan mots maybe old fan motor off wreck car each has 2 if u spill them more success then i like the look of magnet gearbox cheap u tube search no friction or wear hope this helps from mike in aussie ps the fisher and paykel put out ac then need bridge rectiftiar to convert to dc i use the car alt 4 this thow the rest

Wouldn't a load of small permanent magnets fixed around the outer circumference of the wooden ring passing a fixed coil create a voltage? something like that wouldn't put ANY load on the turbine.

Looks great I am working on something very similar, great work!

[WulfBand]

@kevlauenterprises Sorry, Auto Alternators, Any Old School Alternator should work BUT they have to reach a certain RPM to maintain their 13.5 Voltage output. Some will go higher so you would also have to put a Voltage Regulator on it. Some newer Alternators have the Voltage Regulator built in. Soon I will have my gearing finished for my VAWT and send you a video on it. I'm going to hook it up to a dead generator that I salvaged and have a battery bank of 10 12V battery's.

I was going to try a pulley system but though that might put too much drag on it and not allow it to operate in a low wind situation. I left enough room for that or a stator/magnet assembly but all the attempts at one of those failed so far...too much spent on parts.
