cool work 2 thumbs up

[TheNavitas]

Where's Ron Jeremy? The bad 70's porn music in the background totally discredits anything you do.

[MrDelanco]

Some very nice work you have done.

Keep up the good work my friend.

[billmalta1]

WOW! this is what i call a nice winding!!! Great job! I am thumbing you up right now!

[hispanicuscorpus]

how many string of copper in every coil bundle?

[ReignbowSmite]

I would imagine you would have to be pretty prescise with this project. I am guessing it can spin at a pretty good speed, you wouldn't want it ripping itself apart. Thanks for sharing this video! :)

Ok thanks; it looked that way but wanted to check; am going to build axial flux alt for next project; this video helped me a lot. Thanks v much

[7h7gn7fh]

Is it just to hold the coils or has some purpose for ?? Eddys?

[emagnets]

@7h7gn7fh, i am not sure of the question. however, what i have in the video is a how to construct a PMA.

[azterik]

@emagnets I think he was referring to the extra wire intertwined within the coils. I'm assuming just to hold it in place? Very nice build though :) Just one question though, why do you only use bends in your coils and not complete coils (circles)?

[emagnets]

@azterik yep, the interwinding is just for holding the main coils together.

i find that the serpen coil gives me more volts at much lower rpm.

[7h7gn7fh]

What's the purpose of the copper wire holding the 3 sets of winding together (at 4:19 you can see the bright copper single thread around the 3 coils)?

[emagnets]

@7h7gn7fh, it is just that. to hold the coils together and no additional function.

[Luckzzz]

sorry, but what it does?

[emagnets]

@Luckzzz, if you attache it to a prop or any motor, it will produce AC power.

[Caleb6543]

Nice job! I like your fixturing.

[emagnets]

thanks Caleb.

[fuzzyBoy1000]

Where can i get full plans for this pma? I looked at the two sites at the top of this and could'nt see anything. How much power will this put out? Contact me at rfrisby@xmission.com

[emagnets]

@fuzzyBoy, i am the creator of this setup. so you will not find the plans anywhere yet, i will be detailing the plans in the future..

this setup is as follows: with 2 disc magnets i was able to produce 2.2amps and 4vdc at 29rpm shorted.

so with my own calculation, i should be able to make 800w at 400rpm with 35kmh wind speed.

GOOD LUCK SAM:-)

By laminate do you mean laminated steel? i can se how this would increase flux density with 1 disk and also act as a heatsink is this the case? As for drilling holes it does'nt look like there is much space in all that copper for any! Looking forward to the test results . Cheers Jim.

[emagnets]

Jim, yes. Laminate  steel. it sure will increase flux, but i am not sure of the results yet. so wish me luck.

How thick is the finished stator? Nice looking coil . are you worried at all about the wire you have olding it together cutting in and shorting accross the coils when you compress it?

[emagnets]

that would suck if it shorts! i think i will be fine. did it before and all is ok..

[TheJimmax]

Sorry ran out of space! Also im told resin is a poor conductor so thicker stators can have overheating problems, any thoughts? Great work Sam thanks again.

Jim.

[emagnets]

Jim, Time is so valuable these days, small steps, dont over do it on daily bases, that is the trick.

true, that axial flux have a heat issue. i am planing to drill holes through it to assit in cooluing it.

also i am toying with thew idea of using one disc only, and i am planing to place the stator on top steep laminate.

[emagnets]

I am sure i will loos power doing that, but the assembly become very simple and adding the laminate on bottom of stator become possible. all in the testing stages. i will share all my findings good or bad with you all.

Best regards

Hi sam nice looking stator dont know how you find the time my PMA is still on the drawing board! You have got me very curious about serpentine coils I am led to believe that the remenant magnetic flux will be about 50% of the magnets rating as long as the total gap between magnet faces is no more than double the thickness of 1 magnet. eg. 25mm magnet 50mm gap.and that a 10% increase in gap will lead to a 10% loss of power so a thin stator would seem to be an advantage for power .
