I cleanned these with acetone, but it can't be perfectly washed out.

As the chuck spins at high rates, it starts to rotate at different speeds randomly then it stops. This is possibly due to something preventing the motor to run smoothly then leads to a sudden peak current flow burning out the fuse.
