Feigao armature

[GerGa]

The aluminum plate on one of the ends of the armature on my feigao 380c came loose from the magnet and it is free to slide back from the magnet but only about 1/32-1/8 of an inch. How can I fix this? I'm guessing epoxy would but what kind, and I would prefer it would be from towerhobbies since I am ready to order some other things from there too. Also, one of the phases blew a hole in its side and the motor still works, but a little slower, would it be ok to put some sort of non-conductive epoxy in there to keep the little wires from shorting out (more?).

Thanks in advance, Greg

Wick green loc-tite into the endbell gap and quickly...and I mean quickly ..snap it back flush. That's what was recommended to me by someone when the endbell on my Hacker came out.Worked great.

I would use some jbweld, but any epoxy should work. you are referring to the "spacer" on the shaft next to the magnet correct?

Don't know what to say on the windings... I guess if it's not overheating you can just keep running it... and definitely seal any spots that you think will short out or wear more.

I'm talking about the armature, the cylindrical magnet on the shaft...it has an aluminum (or whatever metal it is) disk on each end and its the same diameter as the magnet :teacher: It also has some putty looking green stuff in it which I assume balances the armature. Ya so that is what is loose on the shaft I'm not sure if it can spin on the shaft or not but I know it can move away from the magnet like an eighth inch. I'm not talking about the small brass spacer that goes on the end of the shaft.

Also, am I saying it wrong? Should I say rotor instead of armature?

Its rotor, but we know what you mean. Anyhow, I had the same problem with my 380c 9t rotor. I ended up removing the metal plate completely, because if you don't put it back exactly how it was before, the rotor will be out of balance anyway. Also, don't try to balance it yourself. The magnet will pull itself towards the earth's magnetic field which will make it seem heavier on one side.
