Hi Tim, This …
Hi Tim, This alternator was made with 18 ga wire. The wire was doubled up to make a 15 AWG equivalent conductor. Using 2 strands of 18 instead of 1 strand of 15 will make tighter coils with less space between the wires. This alernator was wound with 60 turns per coil….or 180 turns per phase. There are unlimited combinations: more turns will produce higher voltage…but more turns has more resistance and will make more heat ..or power loss. .. lower efficiency. It’s all about trade-offs.

Ive been following your videos for awhile and cant wait until your system is complete. Im ready to buy and build one. Looking forward to the testing video. What size wire and how many wraps are you using for the coils? Very well done and just what I needed to get me going. Thanks!

The open voltage is …
The open voltage is proportional to the number of turns. From this example…double the turns from 60 to 120 per coil and you will double the voltage. The resistance is a function of the wire size and length. You want to reduce this as much as possible for efficiency. Once you’ve determined the required number of turns for your speed and voltage…then use wire as big as possible to fit in the required space in the stator. I

wouldnt putting like poles together create more of a “compressed” magnetic field in the coil area?
