[generic fantasy] How does a reanimated skeleton power its movements?

If it is the necromancer's magic giving the skeleton energy, why not animate something sturdier than bones, like iron?

Magic energy. That's also why animated skeletons "die" when they are damaged, when the wholeness of the dead body is destroyed, it doesn't function as well as a vessel of magical energy.

Have you ever heard of golems? They are animated statues that can be made of many different materials, most commonly clay, stone or iron.

Although a necromancer couldn't create a golem, since necromancy is all about dead bodies and souls. Unless it was a bone golem or something like that.
