I have 2 kit(s) available at this time. 

Dual Rotor alternator kit 

The kit includes:

2  8 inch magnet plates with holes completed

1  10 inch stator mounting plate holes completed

1  Bearing hub

2  Bearings

1  1 inch shaft

1  shaft locking collar

1  2" magnet disc spacer machined and drilled

24 wedge shaped neodymium magnets

And... all the parts below to complete the wind turbine head

You'll provide the stator, prop and tail feather as per the instructions below..

Instructions: assembly and building the stator in .pdf format  ( about 1.66mb download)

Note:  Don't use the 44 turns to lower cut in speed, it will stall the blades and the performance will be lower until higher winds.  Use the 40 turn coils.  You can increase the blade size to 7 ft and use the 44 turns.

Instructions: building the blades and assembly ( 449kb pdf)

Wiring the turbine ( 140kb pdf 

The entire kit including all of the above for 

$375.00 + shipping

Prop mounting plates shown below are 28.00 and do not come with the kit. 

There is a blade kit that is available and works well with this kit ... just ask! 

These kits will be available for a limited time.   If you have questions feel free to ask

This is a trial for these if you'd like to see other options let me know how you want it and I will see what can be done at a reasonable cost

This kit is based on the dual rotor project on the projects page with the exception of the stator.   The stator will be an easy to build and wire 9 coil design...

Below is a chart showing the performance of the alternator based on a 12volt system.  Remember just because it will perform better doesn't mean you should make it do so.  I've set the furling at around 28 mph so not to exceed 700 watts.

I will be adding things as time goes on so keep checking back from time to time.  If you would like to see other items that are not listed send me an email and let me know what your looking for...

Large Steel Discs

Steel Discs

I have 3 sizes available right now, 8 inch, 10 inch and 12 inch.   All made from 1/4" steel plate.  Great for prop mounting hubs, magnetic discs for use with an axial flux machine or a combination of both. 

8 inch disc $12.95 

10 inch disc $15.95 

12 inch disc $22.95  

All are in stock and ready to ship!

There is no center hole in these but I will mark and center punch them so it will be easy to find and drill the center to any size you desire.  If you know what size hole you need I can drill them for you but there will be a $5.00 set up fee.

Very Large Neodymium Ring magnet sections

If your looking at making lots of power... and I do mean LOTS you may want to investigate the neodymium magnets I've been using for testing.    These are custom made and 16 magnets make an 8 inch OD ring with a 4 inch ID. They are N35 grade neodymium and measure 1.57 inch at the top, .78 inch at the bottom and are 2 inches tall.   These are 1/4 inch thick.   

The above shows the magnets mounted on an 8 inch disc using 12 or 16 poles.  They also fit nice on a 10 inch or the 12 inch discs I sell above. 

NOTE:  Under no circumstances should you attempt to assemble the rings without a steel backing.  They are near impossible to get apart without destroying the magnets or your body!!!!

Comparisons done with the standard 1x2x.5 block magnets...

The block magnets offer 2 sq inches of magnetic surface area where the wedge magnets have 2.35 sq inches.   An example of a 12 pole alternator the blocks would cover 24 sq inches and the wedges cover 28.2 sq inches.   That's 15% more area over the blocks!   It would take 14 block magnets to cover the same area!   

The blocks are 1/2" thick and the wedges are only 1/4" thick.   In the same layout, the 12 pole alternator the blocks offer 6000 gauss in the air gap where the wedges because of their thickness only offer 5500 gauss so you loose 9% of the flux, but remember you gained 15% in surface area.  

Overall, building the same alternator using the wedges came out 11% better in performance. Both alternators were identical with the exception of the magnets that were used.   I was able to use less wire with the wedges over the blocks which in turn lowered the resistance and increased output and made a much more efficient alternator.   Something to consider !

Email me for shipping costs anywhere !

The 3/16 thick wedge magnets are no longer available.   I only have the 1/4" thick magnets 

Sale price on the custom 1/4" thick magnets !!!  $5.95 each

$95.20 set of 16  normally $104.00

$142.80 set of 24 normally $156.00

$190.40 set of 32 normally $208.00
