Follow and revisit this page for latest design!!!!
An ongoing design with the end goal to be a good working DIY wind turbine. I have never made one, drawing and experimenting from info online.
Updates are coming with trail and error over time.
PLS. Comment with any improvement you can think of =).
Republished due to a bug in the old thingpage. (sorry all who had it in lists.)
Soildworks files are included if you want to redesign something.
Knows issues, and hopefully coming improvement:
YOU ARE WERY WELCOME TO HELP WITH THE DESIGN OR ISSUES
-Pole mount with rotation connection for wiring is missing.
-Make the design waterproof
-Alternator house needs a mount for a ball bearing closer to the turbine.
-No design on a "tail wing" so it follows the wind around.
-Housing parts are hard to print the design is warping happy.
-To tight fit here and there.
-Blades are a random design with no what so ever calculation or aerodynamic knowledge behind.
-Missing a sharp nice looking nose cone for the turbine.
-The housing is not possible to fit together the nuts needed to tighten is inside LOL
20140403 Massive uppdate
-Changed from a 1phase to a 3phase design. 12 magnets and 9 coils. (stratorcoils and frame, rotors both, and middistance uppdated.)
-10mm thick magnets instead of 3mm.(rotors uppdated)
-3 mm thicker stratorframe, more space to roll coils. Possible now with thicker magnets. (frame, coils and distance updated)
-moved coils yet a bit towards center for better room for the copper.(colis and rotors updated)
-made the 0.4 walls holding magnets to 0.6.(rotors updated)
-Made the outside diamter of rotors smaller to save some rotating mass. (rotors updated)
-Design error found canât putt lid and wall together and after that tighten the nuts inside! Well driving it without for now needs a new design in the future tho.
-probably needs other types of bearings for forward and backward force. donât know model name though.
-Heads-up, Iâm switching to 10mm thick magnets!! So redesign for it coming.
-Distance rings for bearings.
-Front support added some support and anti-warping.
20140320 parts for mounting on a pole not complete
-Pole mount mountingpeg v1,
-Pole mount upper plate v1
-Baseplate v4 holes and stuff for pole mount.
-Baseplate v3 adjusted hole size for better fitting for bearing, added anti warping thingies.
-Pen and paper.. sitting here and drawing on different solutions for the turning mount... so nothing to show digital. The plan is rings from 22mm copper water pipe and coal from a car alternator some model that are spread around the world. As always all the parts should be possible to obtain or make with tools found in every home.
-Moved colis and magnets 3mm closer to centrum the coil wire in the new v2 config didnât fit. So now Coils v3 and rotors v4. Did also make the rotors 10mm smaller diameter less waste print.
-Coils V2. Made bigger centercore for coils, did read somewhere that the inner width of coils should be the same as the magnets width. Anyone know how it really should be?
-Front support v1. Added a front support with place for a bearing close to the blade hub.
-Backplate V3, Anti warping thingies. New holes for future backswing. Removed holder for backwings and moved bearing inside so it can be printed with the big surface flat on printerbed. Oversized the bearing hole with 0.4 for better fitting.
