Help with this Brushless Generator Design Please

AI Thread Summary
The discussion focuses on designing a brushless generator using concentric rings of magnets and coils, with each ring functioning as an individual generator. The user seeks advice on connecting the three outputs into one, despite varying power levels from each ring. There is a need to determine the polarity of the magnets, which will be alternately oriented. The user is open to more efficient arrangements of the magnets and is considering potential changes to the inner ring due to hub stiffness issues. Overall, the design aims to optimize power generation while addressing structural challenges.

TL;DR Summary
Hi, my first post here, thanks for checking it out!

I am trying to design a generator, which is a mix of several design's I like, based on the attached sketch which indicates layout of magnets and coils...
These components are layed out in concentric rings, the coils of each ring wired as an individual generator... I would like to connect these 3 outputs into one, is this possible? Each ring will produce different levels of power, although I've not done any calcs on potential outputs etc...

I think we need to know the polarity of the magnets.

The magnets will be oriented N/S alternately (I thought this was a constant, however, if there are more efficient arrangements, I'm all ears), and I think will shift one "step" for each ring
 
It is possible the inner ring will change drastically or even be eliminated, as the stiffness of the hub will be an issue
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
