I thought they were called chain guns because they were fed a chain belt of bullets..
The barrels turned via hand crank.
there are different ways to link your ammo, belts, links, linkless. belts are the ones used by infantry in wwii movies. the helicopter scene in the matrix had a good shot of a minigun shedding both shells and the links. linkless is what the gau-8 uses and requires no external linkage connecting the rounds, this is all done by the feed. all can apply mechanical power to the gun while simultaneously feeding ammo.
the minigun, russian rotary cannon, infantry machine guns, etc, all pull ammo into the gun via a belt or ammo chain. the power for this is from the gun, all these examples are gas powered, running on propellant from the cartridge themselves. except the minigun which has a motor rotate the barrels, this is technically part of the gun though and it still pulls ammo. the chain gun does the opposite where the ammo chain being is being pulled through the gun, not only supplying it with ammo but the power to operate. thus it can keep all its propellant for a higher muzzel velocity.
you can argue that rotory guns are sometimes also chain guns in some cases. especially ones with linkless feed systems as they are very similar to those used on chain guns. though i watch a lot of military documentaries and movies and i have never seen a rotory referred to as a chain gun. almost all weapons referenced as such are of the single barrel variety.
