Windy Nation 750 Permanent Magnet Alternator PMA

A look inside an authentic 750 PMA. This PMA is sold exclusively by Windynation. It is built to their specification, with a special stator and magnet combination matched to the needs of the Windtura 750 wind turbine. Don't be fooled by other people showing look-alike motors, implying they are the same thing. They are no where near the same thing.

I do not work for Windy Nation or sell anything; I'm just happy to see a PMA that owners are thrilled with, that meets the specified output, and that is reasonably priced.

On the rotor, are the magnets the shiny things or the dull things? Did you take it apart to find out?

[Fearlessthinker]

@sjh7132 Shiny. They are held in with adhesive. On the Wintura 750, a recent stress test was run with the furling tail disabled to see what would happen in high winds, and at 55-60 mph, they measured 65 amps into a 24 volt bank (was actually at 29V); ~1900w.

@Fearlessthinker I'm surprised that wire would take 65 amps! What gauge is it? Did the alt get hot?

[Fearlessthinker]

@sjh7132 Gauge is proprietary as are the magnet properties. I suspect the PMA did get hot but the conditions were not sustained so the PMA survived the test.

You should put some blades on it that are a little bit longer and better than stock. A six blade that reaches past the 60 inches that you always mentioned. Get a triametric 2525 so you can hook it up to your computer and monitor what its doing over a period. Summer is not the best time to check it out. Best time to put it up though.

@shartne Good thoughts. 5-blade 80-inch windgrabber rotor and grid tie is the plan. Thanks.

@leamyelectricinc1 update works very well.

Bottom line.... big magnents, large coil, and sealed bearing that spin very easy with a stainless steel shaft make up a good PMA PERIOD. This PMA weather used or not does very very well. I own one so i know first hand. Great vid and great PMA. Don't knock to you try it boy's.

[sjh7132]

@Fearlessthinker Well if you are not affiliated with Windy Nation, you could just take a calipers and measure the diameter of the wire. :-)

It's pretty amazing Jeff with his 8 aliases, and Billy, are trying hard to discredit the WN PMA which numerous people have shown can produce over 900 watts at 30mph rather than showing what Jeff's new Renagade PMA and turbines can produce. That Renagade looks inferior to the Patriot/HydrogenAppliances PMAs, so I bet it can't even do 200 watts at 30 mph. Jeff claims he doesn't even own an oscilloscope or even know how to use one, so there is no way his home brew PMA will produce much. ==> SCAM.

[MrSciencePHD]

LOL ... have you seen Billy the Kids videos on what he thinks is a WN PMA? Looks like someone tricked him and sold him an old EFF motor for $400 rather than an authentic WN PMA. The one Billy received does not have the Windy Nation sticker or the cable seal like shown on your video, and the rotor is no where near the same as yours. Windy also has no record of selling a PMA recently to a person named Jimmy, and there is no eBay negative feedback on it. BILLY .... DIY SCAMMED YOU, FOOL!

I think the magnets could be replaced with stronger ones they don't look all that powerful. The size looks ok but they seem kinda weak. The tape didn't stick all that hard it was plain to see. I am read for some real world results with a wind meter and a amp meter to settle this once and for all. It sure seems to be too expensive. wonder where else I could get a motor that don't say windynation for cheaper.
