Toroidal Motor

[Low-Q]

Just one question @broli:

Which picture is correct (Look at the magnetpoles on the outer magnet in your original picture compared to the modified one below)? I got confused by your original picture and asked myself why the outer magnets are attracting each other and not repelling eachother, so I modified your picture below, together with some fluxlines-pictures of original and modified.

Good catch low-q I rendered this one wrong. It should be like you modified it.

Just out of curiosity, what are you using to render the images?

[broli]

Google's sketchup.

Hey broli,

I think this should work.  The torque forces should be the same but because it is on a wheel, I would think the forces toward the outside of the wheel will produce more leverage causing rotation.  Oh but I just realized something, the wire toward the outside of the wheel will be moving at a higher speed, so in fact it will generate a stronger force than the one closer in.  So its going to have a counter emf.  But what is cool is you've invented a homopolar generator that can have multiple turns (instead of just 1).  I suspect that you'll be able to make this device spin so fast it tears itself apart (like a universal motor).  The efficiency should be much better than the conventional homopolar generator too. 

You should patent this if you can.  If you live in the USA, by making it public you've given up your international rights but you can still hold a US patent.  You have like a year after you make it public to apply for a patent.  After that it becomes public domain.

Good luck,
Charlie
