@Groundloop:

After studying your latest illustration more, I see the copper discs are L shaped which leads to the bearings on the axle.  I need to study this idea more.  I don't think this would connect them in series, but I may be missing something.

Nice work!

Actually a N/N/S/S/N/N/S/S configuration may connect the disks in series when they are stacked on the same axle.

I need to take all of this relativity B.S into consideration as far as the different poles of the magnets and different direction of rotations relative to each other, and my head hurts at the moment. LOL

Something that is interesting is to take Groundloop's latest design and incorporate broli's configuration of the magnets in the first post of this thread, which may allow everything to be connected in series at the brushes on the axle without the need for shielding.

I'm just throwing out ideas and thoughts at the moment without thinking things through completely.  I'm not thinking very clear today, so I'll reconsider these ideas when I am.

Thanks,

GB

@yucca,

Do you know if your brushless DC motor for your RC airplane is a Halbach Array rotor.  http://goldeneye.ethz.ch/motoren/electric/inrunner/index_EN/ 

Just curious.

It's an outrunner, so rotating mags on the outside of the stationary coils, I don't know whether the mags are in Hallbach config? Maybe they are?:

I'm running it on a 2A supply at the moment, plenty of torque for disc spinning. It can take 45A all day so I've got plenty left if needed. Brushless motors are cool, only bearing maintenance is needed. If you replace bearings with expensive ones using graphite lube then they can be left alone to just run and run...

@Yucca,
@gravityblock,

If I can get a confirmation that it is possible to use two discs and connect them in series at the rim, thus, doubling the voltage, then I will buy some big Neo discs magnets and try it out. It will not happen until next year.

Regards,
Groundloop.

Great, if it works I'm going to get some big disk neos too. Keep your fingers crossed! ;)
