If you run a DC can motor on AC, it simply won't run. It could damage it if you leave it on too long or crank up the voltage too high. The back-EMF from the motor running limits the current using DC, but since it won't spin with AC, it will just get hot. If he's running a straight can motor locomotive on AC, there's a rectifier in the picture somewhere.
