Rebuiling The Armature On Cat Alternator For Use On A Homemade Windmill
Mike Toppen, Burnips, Mich.: "With all the interest in wind power, lots of people are taking old car alternators and rebuilding the armature for use on a homemade windmill. I've found that by using high power permanent magnets, I can improve power production at lower wind speeds. I press apart the armature and pull out the field coil. Then I repack the field with the magnets and rewind the stator with extra wire. I find these two changes let me produce 13 volts at around 200 rpm compared to the same charge at the 250 rpm speed recommended with a traditional rebuilt alternator."
