New permanent magnet motor on youtube from Roobert33

[maw2432]

Just some observations..
In the Jason George design,  the cam is attached to outside of the wheel giving it little leverage.  Thus no way for it to work because too little leverage is provided.

In the Robert33 design the cam looks to have more leverage to lift the stator because it is attached to the shaft in the center of the rotor.   This design looks to provide much more leverage.   

I think any replications need to consider that the cam leverage may be the key to this working.
Any thoughts on this?

Had a bit of spare time this afternoon, so decided to try out a V-Track idea.

It has worked out pretty well and the idea was to have a V-Track that could be used flat for certain experiments and also be wrapped around a rotor or couple of end caps.

I had a few 10x10mm magnets spare, but more coming in for next weekend, where I will also mill the endcaps as well.

Some quick photos attached.

@CLaNZeR,

This a good idea. Have you made these yourself or these are some available pieces adopted for the purpose? Wonder if you can drill the appropriate beds for the magnets directly on a plastic drum with your CNC or you need a 5-axis CNC?

Hi Omni

I cut this out myself today on my CNC machine to try out the idea.

Much quicker than cutting out a drum as such.

I have cut drums before for some of the E-Orbo designs and also the German motor.

I am setting the turntable by hand for each degree spacing, but never got around to putting a stepper on it and automating it.


I thought the nice thing about having a flexible track is that you can detach it from the rotor end caps and use it for HJ track experiments etc etc

@All

Take two carbon-composite bicycle rear wheels ex-tires, but with their
sprockets and mount them on a frame so that they are in-line and about
two inches apart at the narrowest. Now make the magnet V-gates on
one wheel and the magnet bars on the other. Make a chain connection
so they turn the same direction to stay synchronized. Drop the bars out
at the critical spot and remove them from the 180degree spot for balance
as well.

One may need to replace the bicycle chain with a less stiff ball chain. How
could something like that not work, if there is a constant acceleration force
vector over most of the wheel??? What am I missing?
