Didn't even know he had this page on his site. Completely explains the windings - but not the 5 or 6 magnet issue:
Direct quote and copy from his website below - really good explanation on what charging system is what - with 3amp - what I have - no regulator required and does have a lighting circuit... Brian Miller - a great resource. Brian wpgjetfan
The Alternator (Stator) Charging Systems -
Kohler used six different models of stators on their engines. They are rated at 1.25 amp, which is used only to charge the battery; 3 amp, which is used to charge the battery and supply power for lights and/or an electric PTO clutch; and the 10, 15, 25 and 30 amp stators, which are used to charge the battery and power heavier electrical loads.
The low-output stators (1.25 and 3 amp) require a semiconductor rectifier diode to convert the electrical Alternating Current (AC) to Direct Current (DC) only to recharge the battery. Lights and electric PTO clutches don't require direct current, so they can operate without a diode. And the reason the 1.25 and 3 amp stators don't require a voltage rectifier/regulator is because, for normal use, an average engine don't run long enough for these stators to over-charge the battery, or burn out the lights and/or an electric PTO clutch.
But the high-output stators (10, 15, 25, 30 amp or more), rather it's a charging stator under the flywheel on a small engine or belt-driven automotive-type alternator, require an electronic "rectifier/regulator" to convert the AC to DC (direct current) and to regulate the amount of charge into the battery and limit the amount of voltage throughout the entire electrical system while powering electrical accessories at the same time. The faster the engine runs, the more voltage and amperage the stator produces.
Although very reliable, weather-proof and virtually maintenance-free, this system produces an adequate charge at low idle speeds.
This system is the standard of today's charging systems used on virtually all small engines, motorcycles, snowmobiles, automotive engines, heavy equipment machinery, etc.
And unlike the belt-driven automotive-type alternator, an alternator under the flywheel is self-energizing. It will produce electricity when the flywheel is spun fast enough.
