Stepper motor is a specially designed DC motor that can be driven by giving excitation pulses to the phase windings. They cannot be driven by just connecting the positive and negative leads of the power supply.
They are driven by a stepping sequence which is generated by a controller. The motor moves in steps according to this sequence.
Printers are a great source for stepper motors. Old dot matrix printers have a big and a small stepper motor.
