WIND TURBINE

این تصاویر برای ساخت یک توربین بادی آنقدر گویا است که لازم ندیدم ترجمه کنم. این تصاویر از یک وبلاگ انگلیسی گمنام برداشت شده است

intro DIY 1000 watt wind turbine

A: We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It's a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary.

 

Build the magnet disks

B: We had 12" steel disks hydro cut. We cut a template for mounting the magnets. Then we mounted 12 grade n50 magnets around the outside edge. We then built a form, and poured the resin with hardner.

 

Build the coil disk

C: We wound the nine individual coils, soldered them in a 3 phase wye configuration, and encased them in resin. We used 35 turns of 2 parallel strands of 14 gauge enameled wire for 12 volts. Use 35 turns of single strand for 24 volts.

 

Build the bearing assembly

D: Two Harley Davidson wheel bearings are inserted into the pipe, with a smaller pipe locked between them to keep them in place.

 

construct the blades

The blades are 2" x 6" pine, cut at 10 degrees on a table saw, and sanded into a rough airfoil. Not perfect, but close enough.
