I am in the process of getting a parts list ready so I can order the parts for my generator but I am lost on a few things. I will either be using a 5hp engine or a stream that is in my back yard. My goal is to generate more amperage with low torque but still try and maintain 12, 24, 48 volts. I am thinking of staying along the lines of 48 volts since that seems to be the choice of most others. I don't really have a specific watt range since I want to see how much I can make using different ideas. I would like to see over or well over 1000 watts though. From all the research that I have done over the past few months, I still can't seem to figure out a few questions that I have. Most of the questions that I have been asking are answered with a forum link to another discussion which is no where close to what I am working with.
1 - When building the magnet rotor and using 2" x 1" x 1/2" N52 magnets, do the magnets need to repel or attract the magnet directly next to it on the rotor?
2 - Since I will be using such strong magnets, would using 2 strands of 14 or 12 AWG wire benefit me more than using 1 strand of 13 or 12 AWG since I am working to get more amperage?
3 - How is the output amperage / voltage determined when working with a single test coil? I have read many topics on this but still can't quite grasp where the "other" numbers are coming into play like RMS. Does the output voltage AND amperage get multiplied by the number of coils per phase? So if my test coil puts out 6 volts and 6 amps, I should expect 18 volts and 18 amps per phase?
4 - Since I would like to keep this design as small as possible, what would be the smallest diameter rotor I can get and still have a 3 phase output with 12 magnets and 9 coils based on the size magnets I am getting? I have seen some 12" diameter plates that I can order but the distance between the magnets on the bottom would be close, and from what I have read, too close and they are less efficient.
