Would it go up in flame? Or are all motors used in the usa required to
shutdown gracefully?

Alot of fans/motors are used in commercial applications. I can't imagine
them going up in flames at the end of their lives.
Mine have either broken a wire, and gone open circuit. Or, the bearings
dry out, and they over heat. Often, that causes them to break a wire.

I'm sure motor fires have happened, but I can't say I know of one in my
life.
