i'm trying to understand why it seems all AC generator use the NSNS pattern for the magnet and not just NNNN (or SSSS)...
i'm having trouble finding anything on google (or here on OU) to help explain it better... if you know some links please share them :)
the only difference i can logically think of between the two would be the frequency/hertz the current flows at (NSNS being about half of NNNN i would assume)...
i don't think there would be any voltage or amperage difference between the two... i could be very wrong about that though (i'm still very new to all this)
the only way i could see the NSNS setup producing more volts/amps is on a single rotor with coils on only one side.
i reason the NSNS setup would create a stronger magnetic field close to the rotor (but weaker further away)
HERE'S MY QUESTION
lets say you have two rotors with coils sandwiched between them like this ( this is the magnet N==S )
N==S coil N==S
now the NNNN setup looks like this all the way around the rotor
and the NSNS alternates between
N==S coil N==S
and
S==N coil S==N
given that both of the generator are identical with the only variable being the arrangement of the magnets, would there be any difference between the two besides the frequency/hertz of the current?
thanks in advance for any input you guys are willing to share :D
