Shape of coil windings on a axial flux generator Answered
I am making a axial flux wind turbine. I have watched many tuts on YT and researched alot on the net, but there is one thing that is confusing regarding the coil windings: Does the gap in the middle of the coil have to be the size of the magnet? many people do this and many don't, from a engineering perspective, which is better, my understanding is that it is best to make the gap as small as possible, that way you use up most of the magnetic flux. What is the best approach and why?
