Mini Wind gen question

Posted by Max Schulte on September 16, 2009, 07:51:00 PM

Yes I have the 200w version but only 3 blade. I have had it go thru 2 storms that the weathercube said 50mph gust. But I did have the tail turned 20 degrees.Do you know what speed you had blade failure at?I have had no problems yet that were major only a single rust spot.But I had the inside track and got the body and tail powder coated. I have put it into service now after 3 mo of testing. When I finally put it in its permanate spot the wind stops blowing.LOL Its been 3 wks...

The root cause was a clearance issue of blade to tower. I think the wind was in the 20's with gusts to 30. I really like the little turbine but wish it did not have the cogging effect of getting it to turn. Don with WindGen is right, when it turns, it charges. I have since put up a PrestoWind PMA with the 48" 3-blade kit. It starts turning at around 3-4 mph but low voltage 4-7 volts but when we do get good wind it cranks it out. I had thought about coupling the little generator to the pma and piggyback off the big blades??? Good luck,
David

Last night a blade hit the tower but we had some high gusts.I wonder if I am going to get into a balance problem? lost 1\2 in of blade. Does anyone know what size PCV pipe they make these blades out of?

Max, I have already replaced the blades on mine, this is the response I got from Don with usawindgen:

just thin 4" sewer pipe will work fine

You can take the damaged blade and another blade off and run it with 4 blades if need be.

I know I am not in a good wind area but I have a question? Did you ever put an Amp gauge on your USAwind unit. I got the 200W unit. The best wind I get around here I have squeezed 3 amp burst with 1 amp average. Dont get me wrong I am not complaining I just want to compare.
