I just recently had the plating around the rotor magnet come off. The magnet is still on the rotor but it makes a really bad ticking noise and heats up realy fast. Is there anyway to fix that? So they sell just the rotor anywhere. It was a Feigao 9L.

I've had the magnet seperate (2 Novaks, 1 Feigao) but never had the plating get ripped.
