One can purchase a Stepper motor driver at The Home Depot or Lowes. One can also check on Amazon, ebay, or Craigslist. If you still do not find one you should go to your local hardware store or Sears.
There are a wide array of reputable internet pages from which one could search for and purchase a stepper driver. Examples of such sites include the pages for "Pololu," "Sparkfun Electronics," and eBay.
You could rent a stepper motor at Home depot for a cheap price. You could also purchase one at home depot if you are planning to use the stepper motor for a long time period.
A stepper motor (also referred to as step or stepping motor) is an electromechanical device achieving mechanical movements through conversion of electrical pulses. Stepper motors are driven by digital pulses rather than by a continuous applied voltage. Unlike conventional electric motors which rotate continuously, stepper motors rotate or step in fixed angular increments. A stepper motor is most commonly used for position control. With a stepper motor/driver/controller system design, it is assumed the stepper motor will follow digital instructions. One important aspect of stepper motors is the lack of feedback to maintain control of position, which classifies stepper motors as open-loop systems.
A stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. It moves one step at a time.
A: Stepper motor will move one gradient per pulse the more there are gradients the more accuracy can be achieved

neither. DC locks the rotor of a stepper stationary, pulses applied to a stepper's windings in one order advances it while in the opposite order reverses it. steppers typically have 4 to 6 windings.

There are two different winding configurations for stepper motors. A unipolar stepper motor has one winding coil and a center tap which is activated for proper frequency. The bipolar stepper motor is more complex since the winding motion must be reversed to get the proper frequency.
A stair stepper can be purchased at stores such as Sears, Amazon, Brookestone, and Wal-Mart. It should also be noted that the stores mentioned are a few places that a stepper can be purchased.
Unipolar Stepper MotorsThe unipolar stepper motor operates with one winding with a center tap per phase. Each section of the winding is switched on for each direction of the magnetic field. Each winding is made relatively simple with the commutation circuit, this is done since the arrangement has a magnetic pole which can be reversed without switching the direction of the current. In most cases, given a phase, the common center tap for each winding is the following; three leads per phase and six leads for a regular two phase stepper motor. You will usually see that both these phases are often joined internally, this makes the stepper motor only have five leads. Often a stepper motor controller will be used to activate the drive transistors in the proper order. Since it is quite easy to operate these stepper motors, they are often very popular among hobbyists and are usually the cheapest way to get precise angular movements.Bipolar Stepper MotorsWith bipolar stepper motors there is only a single winding per phase. The driving circuit needs to be more complicated to reverse the magnetic pole, this is done to reverse the current in the winding. This is done with a H-bridge arrangement, however there are several driver chips that can be purchased to make this a more simple task. Unlike the unipolar stepper motor, the bipolar stepper motor has two leads per phase, neither of which are common. Static friction effects do happen with a H-bridge with certain drive topologies, however this can be reduced with dithering the stepper motor signal at a higher frequency.
Applications of Stepper Motor: Computer-controlled stepper motors are one of the most versatile forms of positioning systems. They are typically digitally controlled as part of an open loop system, and are simpler and more rugged than closed loop servo systems. Industrial applications are in high speed pick and place equipment and multi-axis machine CNC machines often directly driving lead screws or ballscrews. In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems. Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, and many more devices. Some people looking for generators for homemade Wind Turbines found success in using stepper motors for generating power.
