Twin rotor axial flux crank drive patent

[Miles]

German patent....

 

[Lebowski]

AEG ?

It seems to be not radial and not axial but the third option where the flux runs in
a circle. I thought about this once but decided it not worth the effort as it only
works when you use iron cores in the coils.

Could well be the AEG design. The priority date of 7th Nov. 2011 would fit with that.

Yes, you're right. I should have looked at the drawings more closely.
Have you read the text Leb?

 

[Lebowski]

I read till i understood the basic idea,there's a lot of legal mumbo jumbo.

Lots of stuff gets invented this way, make a matrix of possibilities (the 3 dimensions
radial, axial and circumvential) and see which one is not known yet (a motor with circumvential
Flux ? Hmmm...) . I once 'invented' gm-C switchcap filters this way.... (which may be in the
receiver ADC of your mobile if you have a few year old Samsung phone)

 

[Miles]

It's principal advantage seems to be ease of manufacture.......

 

[Bikin_Bob]

Is there any other advantage?

Is the AEG motor direct drive?

I saw Bionx has a new large diameter and very flat "D-series" motor does anyone know if this is axial-flux?

 

[Lebowski]

There would be an advantage if you combine this circumvential flux with an in-runner with radial flux, then there's
magnets on three sides and you get about 1.5 times the voltage or about half the losses for the same torque. This
I think is not in the patent but i would gave put it in But as it is described in the patent i don't see any real advantage
wrt axial flux except maybe ease of manufactur...
