"Back EMF" is not caused by an out-of-sync AC system. Back EMF is a fundamental property of an electric motor, because it acts as a generator as well as a motor.

An out-of-sync AC system leads to pole slipping. Generally caused by too much mechanical input to the generator, as long as you've got it in sync before puttng it online. This is certainly noisy in the lab - we did it deliberately once in the heavy electrical lab, much to the annoyance of the lab supervisor. Well, if the lecturer (Prof Laithwaite) has mentioned it, you've got to try it out, haven't you ?

In the real world, it would be destructive.

This much I remember from the heavy electrical course some 40 years ago..
