Tinkering with building a small residential roof mounted wind mill to charge a battery (or batteries). The current rage seems to be PM 12,24,30V motors. Could I use a car alternator to do the same thing? If feasible, would I need a dummy load since most alternators have an internal regulator? Puts and takes, please.

Hi,

I was also thinking why are car alternators not recommended for wind turbines.

I live in Turkey and finding a permanent magnet motor is pretty hard - but car alternators are easy - why can we not use them for wind turbines?

Car alternator is as you know not permanent magnet so to overcome this problem, you can add a battery in between which should also act as a reservoir to provide a continuous supply during off-peak times, regulated flow & obviously magnetize your alternator.

Any car battery or other should do.
