I am not a motor expert, but I know there are posters on this forum that are acquainted with the inner workings of these things. I have a few questions to add on this topic:

Suppose I've run an AM/Banebots/Fisher Price motor in a near stall application and I saw a small bit of smoke and that characteristic smell of a melting motor. The motor still runs afterwards. What was physically damaged when the smoke was released, and how much was the performance of the motor affected? (It is noted that the plastic fan is partially blackened/melted and some of the windings are blackened after this stall period)

Is performance affected if I stall a CIM? No magic smoke is released in that case. What is physically damaged?
