VAWT

thingiverse

This part + https://www.thingiverse.com/thing:2947017 allows for a VAWT equipped with brushless motors. I used Racerstar 1400 & 1600 KV's for testing, They are fastened with M3 screws and bolts. There's also a rectifier chamber to convert the 3-phase into DC. Just add six rectifier diodes, five screws, and bolts, and you're ready to go. After converting into DC, it might be a good idea to add a solar charge controller and a 12-volt lead-acid car battery. It can be a cheap charge controller; mine cost eight dollars. On fully windy days (plus ten hours of wind), it charges a 42-amp-hour car battery from 10 volts to 13.6 volts in seventy-two hours. Compared to the twenty-amp solar panel, it yields about the same, but then again, I might have calculated my rectifier diodes wrong, and someone else might yield more. On playful wind days, as in when there's a gust of wind, then nothing, it is absolutely worthless. It's better to use ordinary brushed DC motors instead.
