Wind Turbine
Description
This Is A 3 Phase (2 Winding Per Phase) 4 Pole Ac Generator. This Uses Powerful Magnets, Handle At Your Own Risk, You Are Liable For Your Own Injuries. So Have Fun :) This Is A Very Time Intensive But Gratifying Project, Especially For A Science Fair Or Alternative Energy. I Wish I Had More Time To Test This To Give You Guys Solid Numbers, So I Apologize. But I Can Tell You Spinning It At A Few Hundred Rpm I Was Able To Produce ~1 Watt From One Of The Three Phases. I Will Be Putting My Smaller Models Of Generators On Here At First Opportunity! Thank You!!(If You Feel Inclined To Tip It Will Go Towards More Alternative Energy Prints!) Parts List: 1/4-20X2 1/4/Bolts----------------------------------(4 Of Them:Stator/Mounting) 4-40X 1.5--------------------------------------------(4 Of Them: Rotor) ~1/8 Diameter Bolts ~2 To 3 Inches In Length--(12 For The Stator Core) 1 Inch Cube N50 Or N52 Magnet----------------(4 For Rotor Poles) ~10$ Each 1/4 Id Inch Ball Bearings 1/2" Od---------------(2 Actobotics/Sparkfun) 1/4 Inch Shaft Spacers-----------------------------(~6 Actobotics/Sparkfun) 1/2Lb 28 Gauge Magnet Wire----------------------(1 Roll Will Do Ya') 1/4 Shaft Collars/Hub/Sprocket------------------(2 Depending On How You Want It Powered) 1/4 D-Shaft 6 To 12" Long------------------------(Actobotics/Sparkfun) The Rotor: I Printed 2 Of The Rotor Files Placed The Magnets And Held The Two Halves Together With A Few 4-40 Nuts And Bolts I Had Laying Around. The Rotor Was Printed To Fit A 1/4 Inch Actobotics D-Shaft. I Used 1 Inch Magnets (4 Of Them) Arranged Alternating N And S (N,S,N,S).

The Bolts Holding The Cap And The Stator Together Are 1/4-20 X 2 1/2". For The "Stator Core" I Used Bolts That Are ~1/8" In Diameter And 2" In Length. Screw The ~1/8" Diameter Bolts Into The 12 Holes On The Side. Pick A Bolt To Start On Wrap 28 Gauge Wire Around Clock-Wise 1400 Times( At 12 O' Clock....This Part Sucks) . Now Without Cutting The Wire Move To The Bolt At A 90 Degree Angle(3 O'Clock) From The Bolt You Just Wrapped And Wrap 1400 Turns Of Wire Around This Bolt In The Counter-Clockwise Direction. Move On To The Bolt At The 6 O'Clock Position(Without Cutting The Wire) And Wind 1400 Times In The Clockwise Direction. Lastly Move On To The 9 O'Clock Bolt And Wind 1400 Turns In The Counter Clock Wise Direction...Whew You Can Cut The Wire ...Now Your A Phase Is Done, Now The B And C Phases. So, Immediately Next To The 12 O'Clock Bolt (The 1 O'Clock Bolt I Guess) Do The Exact Same Thing As The A Phase But The 1 O'Clock Winding Should Be In The Counter Clockwise Direction! Wind 1 O'Clock Counter-Clockwise, 4 O'Clockwise, 7 O'Clock Counter-Clockwise, And The 10 O'Clock Clockwise. This Is Your C Phase. Lastly The 11 O'Clock Bolt Is Wound Counter-Clockwise, 2 O'Clock Clockwise. 5 O'Clock Counter-Clockwise, And The 8 O'Clock Counter-Clockwise. This Is Your B Phase. So Your Rotor Is Assembled And Your Stator Is Wound. Now Place A Shaft Collar On The Shaft And Tighten It Down At Your Desired Length From The End(Leave Space For Rotor Ect.). Now Stack On Top Of The Shaft Collar A Shaft Spacer, A 1/4 Bearing, 2 To 3 More Shaft Spacers To Keep Your Rotor From Hitting The Casing While Rotating, Your Rotor(May Have To Be Pressed In With A Vice Or Heat The Shaft Depending On Tolerance...Be Careful!!!), Then 2 To 3 More Shaft Spacers, The Second Bearing, One More Spacer, And Finally Your Hub/Shaft Collar/Sprocket. Boom...Spin And Produce All Of The Electricity! Wire In Delta Or Wye Configuration.The Blades I Made For The Wind Turbine Were Made Following These Instructions ---> Http://Greenterrafirma.Com/Making-Pvc-Wind-Turbine-Blades.Html Use A Hub To Mount Them Or Thread The Shaft And Use Bolts! I'Ve Not Been Able To Do Much Testing Because I Work 12 Hours A Day 7 Days A Week, But In The Back Of A Pickup Truck Going 15 Mph It Easily Produced 20 Volts. Lastly The Output Can Be Increased Just A Tad By Creating A Complete Path For The Magnetic Flux. I Used Hobby Strips Of Stainless Steel Around The Outside To Create A Return Path For The Flux.
