Double Rotor Generator / Different Speeds

[Jim Mac]

This next attempt is similar to the idea in the last post..    For those familiar with how Lenz and Magnetic cancellation work when 2 opposite poles cross a coil, study the geometry and passing of the magnets.




I can spin the rotor with 1/2 a watt input..  I made it so I can pour a resin / Iron powder core inside the pyramid later.  You will see how 2 magnetic poles pass 1 coil..  The dynamics of when the magnetic field grows and shrinks is severely altered when compared to a standard generator.  Due to magnetic cancellation of dual poles and the geometry of the coil, the wave will not be sine-like.  

I have made a sloppier model with an air coil and it was interesting, which is why I wanted to circle back to this..   

I am re-printing the pyramid stator because of mounting issues..  But you can see the main idea and angles from this..  Obviously the coil will wrap around the triangle frame and if justified, a resin / iron core poured later

Nice work Jim, I don't know how I missed this thread last year.

Anyhow, you've given me an idea on how I can apply this to the Axial using an additional half size rotor and coils that connect back to the generator coils.

That's what it's all about..  I read posts on other forums that suggest it's a waste of time posting projects, ideas and updates and we should only share if successful..  I fully disagree with that school of thought..  

Posting ideas, steps, and failures can and does trigger ideas in others..  

Anyway, I had to print the stator 3 times due to small errors..  I am winding the triangle coil now  Guests cannot see images in the messages. Please register at the forum by clicking here to see images.

And it's a cool little setup where I can wind different stator patterns,  so when this fails, the setup cab be reused

Well it's running and I have numbers to present.

For a single air-core coil, the output is pretty decent..  Not overunity, but it has some respectable output.  



I will probably switch the output with a hall sensor in different positions, to see if there is anything to be found..

[Jim Mac]

I hand-tested positions with the scope..  As expected (and hoped)  there is a polarity flip at this position.

   

When the 2 rotor magnets are at 12:00 and 6:00 (both within the triangle) the output is zero, meaning the neutralization works as intended.  

I don't have time to do the next tests at the moment, but the question is:  which hemisphere of the triangle influences the magnet more at the position shown.  The bottom BLUE is repelled out and the top RED is drawn in.  And powering the coil shows one hemisphere is indeed affecting the magnet more..  

IF the hemisphere affecting the BLUE magnet is affecting it more, then we have a winner..  Meaning the output can be switched at that time..  But I am not getting my hopes up..  Magnetism usually has a way of foiling all plans..

I'm going to guess the bottom hemisphere due to a magnet traversing the coil 4 times, rather than twice at the top. Clever design getting double pulse and single pulse in the same rotation.

I'm going to add that a North field is stronger, so the BLUE magnet will benefit more from the RED magnet. There is also the angle that the magnets cross the isosceles coil that will come into play.
