DIY wind power - Stepper Motor Micro Wind Turbine Generator PMA DIY Homemade

This is a micro wind turbine I designed and made based on a NEMA 23 brushless stepper motor. While these motors are not designed to be used outside they are perfectly capable for generating a small amount of AC current and hold up surprisingly well. Although I have not done so on this unit the magnet rotor and stator coils could be dipped in spar urethane and bearings replaced with weather sealed one's. Having taken many of these apart most have 627's AKA roller skate board bearings which are inexpensive and can take abuse. Also, these motors can be had in many different voltage and amp ratings depending how you want your output. The frame or nacelle I intended to keep simple with a light tail vein to track the wind fast and accurate yet a balanced center of gravity on the pivot bearings. Since it lives near the ground in an urban environment it rarely sees a strait line wind so needs to find the direction fast and pick up speed before it changes direction again. For the most part all materials are easily available and reasonably inexpensive although there is some machining time involved. Hope you enjoy and please rate, comment and share your ideas. Thank you
