Dia. Mag. Alternator

Finished off the windings.
This time the slots are full.
The first wind had about half the slot.
Its really light, about 10 ounces.
DiaMag6 weight 10 pounds.  LOL!
Time to build a test bed...

Great build z.

Hahahahaha, Fork Yeah!

The coil develops 2.2 Volts, and there is current behind it this time.
I light one bulb 2.2 Volts.  I light 4 bulbs 2.2 Volts.  The coil is 1.6 Ohms.
Some of that is DMM error, like 0.6 Ohms.  So as measured I can drive
1.375 Amps, and is probably more like 2 Amps.  So its somewhere between
3.0 and 4.2 Watts, about 6 to 8 times more power than DiaMag6...

Oh yeah, only one winding is hooked up...  2X in the near future...

Great build z.

Thanks Cap-Z-ro...
It took me a year to make 3 Watts...
I hope this is an exponential curve...

Got everything mounted to a test block.  I used a couple of Full Wave Schottky Bridge Rectifiers to rectify each coil.  Then connected them in series.  2.2 VAC on each coil, added, then subtract the diode voltage drops.  The result on the load is 2.7 Volts, bulbs are brighter.  The total diode Voltage drop is 1.7 Volts.  So, 0.425 Volts each way, times two full bridge rectifiers.  I selected the Schottky diode because of the low forward Voltage drop, but also because they a high current parts, one Amp continuous, 25 Amp surge.  Now I am utilizing both coils, and I can see how much current I can drive.  Also thinking that the wire I chose is too big, and I need to use 24AWG or 26 AWG to get the Voltage up.  Maybe, not by unwinding this one again, but make another one.  The labor on the DiaMag7 is a couple days, while replicating the Iron Stator on DiaMag6 would take a couple of months.  I need to do some more testing, find heavier loads...
