my new hornet 6 blade pma1000watt 12volt turbine is very stiff and wont start up at low wind speed,-any help.?
can i do anything with it to have it start up at low wind speed.
is there grease in the bearings? does it have bearing? more and more motors I see are using air bearings .. hmmm ... I would modify the air foil shape and propeller size to minimize the startup speed requirement. But one would think that the manufactures already done such things? .. Or you can lift the turbine to a higher elevation? ..
How much did it cost you to build a wind turbine?
I've studied them on instructables.com, youtube, and my state websites. I know enough about the technology to build it. I was wondering if anyone has actually built there own and how much it cost. How much of your set up was bought new and how much was salvaged? I've seen the estimates of $1,000 per kw and I just don't believe that that can be accurate if you're doing everything yourself
I used a 90v DC motor before, but due to my location, I never really had enough wind to power it often, so I use solar panels. You should also use a strong bridge diode as well with a charge controller to keep your cells from overcharging on windy days. I built my own charging system a few years back using relay switches, and two transistors. This design will work in all wind directions, thought it was kind of cool.
