Yes…nicely stated! I totally agree and find this comment much more appropriate than calling someone “stupid”.

Yes, indeed they are well informed, but not all do-it-yourself builders are. I must insist that even though these particular permanent magnets aren’t ‘dismembering’ the assembler, permanent magnets of this size are dangerous. Having said this, it also stands to reason that not all magnets of this size are of the same strength. An equally sized magnet of greater strength could easily crush the fingers or break bones.

“Stupid even”…?
I can’t see anything STUPID here. These guys are pretty smart IMHO. Check out the footage around 3:18…. harmless! He does it twice!
No blood, no dismemberment…just a harmless test.

Placing your hands …
Placing your hands between permanent magnets of this size is inadvisable, stupid even. Use a smaller magnet to determine polarity.

I cant wait to see what it does when you test it in the shop.
I have looked for this type of info for over a month. This is AWSOME !!
You guys did a Great Job. Please make more. Those are some strong magnets. I was afraid that poor guy was going to get pinched.

@wind2volts – …
@wind2volts – could you just put all north on one disc and all south on the other? Why do they need to be alternated like that if both discs spin?

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

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!
