Hi,
I am new here. I am working on a small alternator project that does not involve wind or alternative power use, so please excuse my intrusion. I am currently stumped at the moment, but I know the expertise can probably be found on this site. I want to build a small PM alternator for operation in the 350-500 RPM range to produce a usable 12v output, but 6v may be an alternative output. The stator outside diameter cannot be over 4". The output needed is approximately 25-30 watts. The output would be rectified to DC, controlled with an voltage regulator, and used for resistive lighting. I have considered a small Denso industrial engine 3 phase alternator stator, but I don't think these stators use more stator coil wire turns to produce the higher voltage. As you can guess, I am trying to avoid rewinding any potential use stator, if at all possible. Any suggestions on potential stators, or any other suggestions would be greatly appreciated.
