rotor
Hi Gyula, Sorry - my quick drawing was not very detailed. I was imagining bearings on the three contact rotor positions, where they meet the larger hub. Allowing physical (rolling) contact of the brass with the dual aluminum surfaces, along with conventional center shaft and bearings (stainless balls and plastic housings). I'll assemble some more images.
In the linear design; the rotor needs physical contact with the aluminum or copper rails, it needs to rotate at a reasonable RPM (tests indicate 1600-2200range or more) through the magnetic fields.
A different consideration was to have a fixed outside housing, allowing the stator portion to "rotate" in the opposite direction of the spinning rotor. In some of my early attempts, problems were created by "conflicting" magnetic fields. Fields that were "spread out" in linear and not an issue.
I am considering building another semi "linear" design, more like a "roller coaster" with full 360 degree loops to study the concept more in depth.
