Motor and Switch Assembly
The smoking is caused by thermal decomposition of the potting compound on the Electronic Speed Controller (ESC) or the varnish on the stator windings due to excessive current draw. In brushless DC systems, the MOSFET bridge manages high-frequency switching; if these components fail or short, they release significant heat and smoke. This assembly includes the motor, controller, and switch, which are typically non-serviceable at the component level.
