These work well for the Micro and small wind turbine generators. We at Missouri Wind and Solar ” MWands ” no longer use the slant or super core rotors. We manufacture our own Renagade pma’s and rotors. Here’s a good link to a wind and solar forum http

You ooze? credibility. Thank you!
how much watts it? produces @ what rpm
i dont see it giving power then how it a permanent magnet altenator
why it is called like that
where? is the free energy i dont see it
how many amps u got ????
too many questions
A 3 phase induction motor (made in China or made in America) is more economical to convert. All you need are permanent magnets? embedded on the rotor. Ferrite or ceramic magnets will do.
Thanks man, your videos are awesome! Couldn’t have done this without your info. Keep up? the good work!
Sounds like your doing? something right to me.
Jeff
I just converted my rotor to a makeshift wooden block with some neo magnets. Im getting over 100v just hand turning it. Did i overkill on? the magnets? The amps are off the chart aswell!!
It was so interesting to watch those 2 instruction videos, as I am building one windmill right now; and I learned a lot from this, avoiding mistakes; but two things were not said, that? I was hoping to hear…. how does the diameter of those magnets you replace match, and are all car alternator of the same diameter or size???
And; car alternators are very easy to revolt; are those PMA very hard to revolt, as the magnets are very strong; I hope you would show that by revolting them by your fingers
i want to buy 1 of these from you? how much £££
I’m thinking what is PMA LoL… I guess was blinded, not? reading well.
Some beer and a garage? made many a happy man.
I have one of these PMAs and it is very hard to spin the shaft. I have had it on a drill to burn it in for a couple of weeks and it is still hard to spin. Any ideas as to how to? improve the ease of spinning?
I? would keep the fan on for cooling.
we sell them on our? website
Jeff
the first one did? not go back together very well
im a fabracator welder .im getting into to this build your own stuff . let me know? how i can help
Jeff. I assume you can leave out the diods and run this PMA 3ph AC? What if I wanted to connect 2 or more in parallel to boost the amps? Can I do that AC or? would I have to output DC? Have you done any work with gear reduction to increase the PMA rpm?
ola sou do? brasil e gostaria de pode adiqueri estes imas?????????????
They’re for wind generators, for? making your own electricity.
Hi there…I’m putting together a very effective hho unit and would really like? to have more power running through the cells……what would you recommend
cool :)?
hey? there! i was wondering were can i get these rotors(cores) and coils?
It’s true that certain paints can help radiate heat off. The best color is black, as in “black body radiation”. I use Krylon’s flat black.You would, of course, want to paint very, very carefully, so you only paint the outside of the alternator, and not into any of the ventilation holes or electrical connection areas. (For example, volts? X amps = watts. So, 500 watts at 12 volts = 500/12 = 41 amps, and that’s one heck of a lot of current — use thick wiring! 41 amps can start a car.)
you cannot use a factory rotor.if you do it will have to hit 1200 rpm’s to excite the stator and put out power. about 30 mph winds? to get that.
jeff
How much power is used or lost? if a regular factory rotor is used.
Is it practical to use a factory 200amp GM alternator for a wind generator; if so …..
what size/feet blades would you recommend?
Thanks
