sir, there are no alternators equipped with armatures. motors do. the rotor or rotating field coil's slip rings does not indeed stop rotation of the rotor or field coil and is not strong enough to stop rotation, it will snap. the carbon brushes are never enclosed in metal casing or a severe short circuit happens.
