The fan motor is burned, the motor is turned on, and the copper wires are turned round and round, but no break is found! What the hell was that?
Don't use it. As long as the coil of the motor was burned. The destruction of the coil insulation will. No repair. Only rewinding coil.
You see the coil is called enameled wire, the surface of the insulating paint, you see the smoke is actually the coil surface insulation paint burned out, if it is slight, you can not see, you need to use multimeter measurement. Also, some motors have a high temperature insurance, may also burn out
The hero, I really admire your behavior, but also really admire, as a person who does not understand the circuit can do so, it is very rare
