maybe I dont understand what you are trying to do
Looking at the photos I can see a shaft
I assume inside the box is a disc with magnets attached
If this is correct and you connect all the coils in series the induced currents will all be out of phase'
re 2nd para If you have two coils in the machine and they are correctly polarised you will get 120 v on each ie 240 v but still 4 amps
When you put the other 4 coils in the machine you will get the same voltages but out of phase by 120 deg each This does not matter when you rectify the 3 outputs
I am surprised that you get 4 amps as the magnetic field is not closed.
If you look inside any induction motor or alternator you will see that the stator has a magnetic core and so has the rotor and a small air gap between the two .
To get this to work you need to close the magnetic path to approx 1 mm
If you try mild steel you will have a lot of losses due to eddy currents generated by the ac and put a lot of load on the driver . In motors and generators the magnetic field comprise of laminations of electrical steel. these are 12 thou thick and insulated on each surface to block eddy currents
