While the rotor was accesible various examples similar to the above were held near the rotor to test for improved stability. It is quite amazing the power of the repelling force even as far away as 100mm. This was the best arrangement found. The holder was then modified to have the magnets alternating on each side at each frame section, and also the radial magnet clearance increased by 12mm to 27mm. Because this test component is not a full circle, and has no steel backing band, the actual in place performance of this layout is just guesswork.
