All Permanent Magnet Motor

[synchro1]

What would keep a builder from locking the top ring to an overhead gantry and allowing the lower ring to spin? This would bypass any imbalances in the setup. I have sourced a set of 5.3 inch rings and 1X2X.5  n45 neos. This is really a simple thing to knock out so decided to do it. I have 5 weeks off at the moment so why not. I will be setting the inside of whichever ring is to move with 3D printed pair that will have skate bearings in both sides. Thanks Magg for sharing as I need things to keep busy with. Love to play with magnets anyhow.

    That will have to hold until the mags get here. Just ordered them. I will be setting up a jig that will be able to allow me to do both. I am in the run to print up the mounting plates for the ring mags now. Going to use skate bearings on both setups so to aid in the turning on the shaft. In the end, if this goes, I will make the shaft rotate with the movable ring to be able to draw out movement. Not sure that this will have much torque tho. Will just have to wait and see.
    For what it cost to set this up, well worth the time and cash to play with. No loss on the rings as in the end I have another use for them anyhow.

@Thay,


One good 3rd party replication is all it will take to put this motor on prime time news!

This is the latest revision.
Cancel the rod magnet feeding into the center part of the 45 degree angle.
Instead place the rod magnets North Pole again the North Pole of the center block magnet.
Watch what happens. The 45 degree framework will move counterclockwise.

skate bearings is no go. You have to use non-magnetic materials, like brass for example. My main problem at the moment is to find brass/plastic ball bearings - if not successfull will use the non-ball bearings - brass/plastic ones. And last problem - the shaft - it also needs to be non magnetic - probably will also use brass.
