Building an 8-foot wind turbine Brent Summerville Appalachian State University
Research: In search of Plans Backhome Magazine article www.backhomemagazine.com www.backhomemagazine.com www.otherpower.com …derived from Hugh Piggott’s axial flux plans or “How to build a wind turbine” Go with the source and follow plans closely
Research: Hugh Piggott Workshops in Washington, Scoraig, CAT, Edinburgh, Ghana, France, Costa Rica, Liverpool….. This is Jay from France. He also came to a Beech Mountain workshop.
Resources: Woods Lab Sat in on Intro to Wood Technology Trained on techniques, tools, machinery and safety Practice…Sanding block, cedar tool box Last semester for Bill Hanner Draw knife Hand plane Spoke shave Lathe Jointer Sanders Gluing panels Planer Bandsaw Drill press Table saw…
Resources: Metals Lab Sat in on Intro class Trained on techniques, tools, and machinery Copper nameplate, dinner bell, apple butter stand Nice working with Leo and Dave Welding Mill Lathe Plasma torch Blacksmithing Grinding Tapping Sheet metal fab Drill press Iron worker…
Axial Flux Alternator: Magic Most of the electric power in the world is 3 phase. The concept was originally conceived by Nikola Tesla and was proven that 3 phase was far superior to single phase power. 3 phase power is typically 150% more efficient than single phase in the same power range. In a single phase unit the power falls to zero three times during each cycle, in 3 phase it never drops to zero. The power delivered to the load is the same at any instant. Also, in 3 phase the conductors need only be 75% the size of conductors for single phase for the same power output. source: www.windstuffnow.com/ main/3_phase_basics.htm An electrically charged particle moving in a magnetic field will experience a force (known as the Lorentz force) pushing it in a direction perpendicular to the magnetic field and the direction of motion: Source: http://www.wondermagnet.com/magfaq.ht ml#q18 Rectified to DC (one phase shown)
