Greetings, I am searching for ideas to increase the RPMs of a vertical axis wind turbine that I am working on. I am able to fabricate the design show. If anyone can suggest modifications please let me know. Top recorded RPM is 200 RPMs at 50 MPH. Comments welcome.

Greetings, I had some time to create a visual aid of would I believe the lines of flux may look like when the rotors and stators are stacked vertically. Stacking the rotors and stators vertically require ½ the magnet count then using traditional fabrication techniques. Example: 3 phase, 8...

Greetings, here is better picture of the top and bottom rotors. The metal ring contains the lines of flux and prevents eddy currents from forming on any metal part in close proximity which can cause a undesired breaking affect. When the stators are installed the air gap between the rotors and...

Greetings, photo of stators being used for project.http://files.engineering.com/getfile.aspx?folder=e7fb4829-c935-464e-9fa0-a026dc4735d9&file=stators.jpg

Greetings, additional photos of project. Is there away to add more then one attachment to a single post? http://files.engineering.com/getfile.aspx?folder=1b76d9d9-b0da-424b-8d71-67064ec4cb5c&file=AddedMetalRings.jpg

Greetings, I am working on a design for a vertically stacked stators and rotors permanent magnet alternator. Traditional fabrication techniques fabricate the axial flux design using one stator and dual rotors to create the device. The approach I am experimenting with has 3 stators and 4 rotors...
