then you need a little more rpm to get the alternator to charge above the battery voltage. About 13.5 volts. The average alternator is now between 1,300 to 2,100 rpm. I set up an old 35 amp alternator to run off a 1/3 hp 1,750 rpm washing machine motor at a 1:1 belt ratio. Using the stock regulator would stall the 1/3hp motor. I put a large adjustable resister on the field connection of the alternator.
This alternator gives better amps than the 540, but it doesnât start charging a 12-Volt battery until you have a very steady 9 mph wind. At about 12 mph wind, the alternator was able to produce 3-5 amps. In 20-25 mph wind, the 540 was producing 12-17 amps which is a respectable amount of power for a small PMA.
