Hi Cody,
It looks like you are off to a good start now. Have you leveled your rotor surface in 2 directions (front to back, and left to right)? Did you lay all your magnets down with north side up? What size are those bar magnets? Looks like you are using Masonite for your rotor, is that correct? It's good that you laid it out with the concentric circular lines.
You're quite right, Cody, the fine tuning is going to be different for every build, even when using the same parts. It is dependent on so many factors - leveling, balancing, friction, magnet strengths, etc. Magnetic balancing can be just as important as mechanical and rotational balancing. The bar magnets will have varying strengths, and it will work out best if you can arrange each group of three to have a nearly equal total repulsive force. You could use a small neo cylinder magnet, inserted in a clear glass or plastic tube, placed above each bar magnet in repulsive mode, to test the separation distance in millimeters. Then arrange each group to average out the same. You will probably find that the strongest magnet of each group does better if placed in a particular location within that group. If it is the leading magnet to approach the stator, the anti-rotational repulsive force may be too strong, so you may need to shield the magnet or move it to the center or tail end of the group. It's just a matter of getting the right combination of forces working for you, but it won't be easy. Thanks for the pics, and keep us posted on your progress.
Best regards,
Rick
