What will happen if the back emf of a DC motor vanishes suddenly?

If the back emf of a DC motor vanishes suddenly motor circuit will try to retain back emf by drawing more current from the supply. If supplying unit didn’t trip down by this time, excess current in the armature may heat up the armature.
