DIY Wind turbine

[Chris Hobson]

Cannot vouch for this at all. Looks Heath - Robinson but members may be willing to give it a bash. I cannot use all the power from my panels so I am not looking for extra projects. The extra power at night would be a bonus though.

Alternator needs field windings to be excited, usually via a small lamp that also doubles as the no-charge indicator. Also, that pathetic little fan is never going to turn it fast enough to make anything meaningful :-) A quick google suggests that alternator/engine pulley ratio is between 2 and 3, so if the engine idles at say 700RPM, that means you need 1400rpm to 2100rpm to make meaningful power.

Soooo... you're talking a windmill wheel with a 15:1 pulley ratio, if my memory of the average speed of a windmill wheel in light wind is anything to go by.

You could buy the magnetic rotor and the 36-pole stator of a LG Direct drive washing machine and make your own machine by adding support and a shaft. The blades can be made of plastic cutting out the profiles from blue pvc pipe, or you could make the blades from other materials.

The off grid quest will continue with that contraption!

Excellent project this... won't be climbing that myself though!!

Utterly amazing contraption. Sad that the practical experience will die with the old man. I remember watching my dad shoe horses and being fascinated as a child. It is not a skill I ever learnt since shortly thereafter we stopped using horses for stockwork.

Great insight into the build just subscribed and it’s a nice compact turbine I also have built a homemade 650 watts wind turbine, a treadmill motor turbine and a little but powerful ametek 30v turbine and built 2 diy solar panels, be careful in high winds one of my first turbines blew up and now have only 2 wonderful turbines working daily it’s very satisfying watching those things working, keep up the good work buddy

my channel with all my crazy wind turbines are at https://studio.youtube.com/channel/UCcBS6Mgm3AAjYp0z596IL8w 

i am hoping to build a 7 to 10 kw home made wind turbine, but may need further advice from you guys on the electrics front

hope you enjoy it
