@goose2goose2 Actually I experienced the issue when there was just the brass rod & the axial magnets in the system, so I'm inclined to dismiss the effect as a centering problem. But appreciate the input Tnx
Hello, I've noticed the exact same magnetic imbalance with my experiments and have tried the same corrective measures. I have a setup made from ring and cylinder magnets and the air gap can be very small, but the smaller it is the more cogging effect. This unbalance can really through off your attempt for perfect balance. The rotor can be balanced to overcome some of the cogging but then at high speeds the rotor really gets off balance again.
Thanks... (Good question) Search 'Mendocino" on You Tube. There are examples of almost every imaginable type of field magnet. Since these motors were built mainly for "Minimalist" effect, not power, anything that turns is a success. But to your point, (all else being equal) the more field flux in the armature's path, the more readily (efficiently) it should turn . The arrangement shown here was clearly a trade off between results Vs ease of construction.
Sorry but I don't understand what's the advantage of this motor. Isn't it better to put the solar panels outside the motor to make it less heavy?

it's out of balance due to a lack of perfect centering of the shaft through
the plexiglass box.
when you do it again, take more time on the centering, and use a solid
SS rod..it will run truer.

Very nice job and explanation.
Thanks

Never seen one of these before! Interesting, would this work even better with flat bar magnets ?
Nice work :)
