I understand that this question has been asked before, but I've seen so many different formulas that I'm questioning which one is applicable to my situation. What are the correct formulas I need to build an alternator to meet certain requirements? I need to meet a specific voltage and amperage requirements and that's it. I need to know how many coils, what gauge wire in the coils, how many magnets, what size magnets, what gauss magnets, air gap... Essentially everything. Is there anyone that can help me calculate all of this?
