Axial flux generator dual rotor question

[jearls74]

I am building an axial flux generator with dual rotor and single stator. I was doing calculations and have a magnet pole pair question i need help with, there are 12 magnets on each rotor with North pole on one rotor across from South pole on the other rotor.

Since there are 24 total magnets positioned in a way for the flux to travel from a North pole, through the stator and into a South pole, is this consider one pole pair?

Or do the North and South magnets have to be on the same rotor to count as a pair?

Are there six pole pairs or are there 12 pole pairs?

The axial flux alternator is a simple three-phase alternator. Each time a coil sees a flux change (North to South) requires a "Pair". So, 12 positions (24 magnets in your case) is six pairs.
