I'm building a small generator and would like to get an approximate guess for the number of force lines. They are N42 Neo's. Sized 1inch by 2inch by 1/2 thick. Poles through thickness. Stacked in a pile of 3. For a total pole length of 1.5 inches.
It is a consequent pole frame and there are two of the three piece magnet stacks, one on each side. I've been using 90,000 lines/sq.in. but I think this might be to high.
The core is compressed iron powder and epoxy and the air gap distance to the core is .092". So total gap of .184" , call it 3/16 inch.
I can post some pictures of the rotor and magnet frame if they would help. I ask because I understand small generators and consequent pole types especially have more field leakage than other types or sizes. Is 90,000 lines to high with the gap and type of generator?
Any educated guesses would be welcome, facts will be given front row seats.
