Hi Magz, Marius

Marius that sounds pretty crazy ! Strange things were happening with Magz' setup as well with caps inline.

Hey Marius and Deep



Marius,  I would love to see a vid on the post you just wrote.  ;]

Hi Mags

Well, bad news.
9000 rpm was a little too much for my rotor. I dont want to destroy anything around

Hey Marius

You can fix that.  If you have access to fiberglass, thin "cloth" as in woven not "mat" that is random fibers.  4oz cloth is thin.
Use a thin superglue. 2 wraps around the edge should do. Superglue is about as strong as resin, but its the glass that has the strength. If done neatly, it will add only less than 1/8 in to the diameter. Superglue the cracks also before applying the glass.

Very nice mold of your rotor by the way. ;] Did you use tabletop resin?  Great balancing job also.  ;]

You could glass the top and bottom surface also. This should solidify your rotor well. Use resin.

@Marius

What you could do to prevent that breaking is a slightly different rotor design.

Use two, thinner, discs and superglue the magnets in between them.

Then again, i haven't used that design at 9,000 RPM !

Or wind more thin wire to make coils with more inductance - that drops resonant frequency as well but raises operational voltage.
