New Stagger Stator PMM Design. Review wanted before construction.

the spinner would be fun if you want to give it a go, however it won't work on a fixed axle (lazysuzan) the metal ball allows the donut magnet to change angles and posistion relative to the stator, if you lock it up it doesn't do much. Also use rectangle mag with a hole in the center, not just rectangles.

Why do you say rectangles with a hole? You kind of lost me on the spinner comment. His spinner doesn't have a donut magnet?

I am also still working with the 3+ rotor with continuous/staggered track and perpendicular sliding rotor design. I have spent a few dollars already and I want to design it more before spending to much more. I have a feeling that the force generated by having 2 or more rotors in the middle/end(acceleration) of the tracks wanting to rotate the wheel is going to be far less then whats needed to push the 3rd rotor "around" the repulsion point. But I have now way of calculating this.

I thought you were refering to the hamel spinner mag motor. Were you talking about the "brushed" motor design?

I was talking about this "magnetic spinner" desgin: http://www.youtube.com/watch?v=91iCppzXuXw

I tried a simple reproduction using a 18" plastic turn table instead of this aluminum disc. I also used the 3/4" ceramic disk magnets from the rails I built instead of the neos and I had two of the rectangle magnets he had used in the video. My results were not that good. I couldn't find the polar configuration that would give me any kind of result like his. I haven't heard a word from him so I'm assuming he is either trying to build the full thing or had realized his oversights.

An update of my current design: I think I have ruled out using a sliding track like in the picture below and feel some kind of balanced hinge arm would be better. I will try to put some graphics together expressing this more. Let me try to solidify a design and figure a why to logically document and express it and I will post again.

Does anyone think the "magnetic spinner" is worth replicating? I think I could replicate it for $20 or so using a plastic lazy Susan turn table and ceramic disc magnets (which I now have a lot of) or if I had to I could buy the same kind of neos. I'm sure I'll probably run into the same problem I had with Tom's rails but I wanted to see what you all though?

You can try to replicate it. It seems quite straight forward - there are probably not very complicated math behind this disc...
