Stepper motors are different from DC motors in that they have to be pulsed to move in set increments. That means you can't simply hook them up to a power supply to make them go, but they have other advantages, like accurate positioning (1 pulse=1 increment of movement), and lots of low-speed torque (ability to twist things). The flip side is that they are power-pigs, but ya gotta love this sort of pig!

These stepper motors are extra special
