Do you remember how it "blew up"? I'm uncertain about just how a motor
would do that. Some possible results that come to mind:
* Windings repel themselves (possible explosion)
* Shake to pieces (possible explosion)
* Windings vaporize (possible explosion)
* Melt
And did any of the fragments hit you?
BTW: my father saw this and remembered how when he was young, he used AC
line plugs and sockets for other types of connections (because they were
cheap). One item was a pair of shortwave headphones. One of his younger
siblings got hold of it one day and plugged it in - the whole house
heard it instantly.
