NEMA17 32.5:1 Geared Stepper Motor

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
