Did that driver IC not explode causing the black carbon?

How does that work exactly ?
Best to be in another room, if possible, when that malarky's going on.

The motor is on its third set of brushes. The black carbon turned out to be carbon dust from the brushes. Nothing wrong with the commutator or the brushes - it has just been used rather a lot since 2005.
I have no idea how/why/when the carbon dust collected in the way it did! I assumed it was the product of combustion of failed components as well.
