Stepper motors are commonly USED in robotics, plotters, printers, valve control or other precision aplications where exact control of positioning is required. Although they typically provide a rotational force (there are linear steppers also but they are rare), their energy can be USED for linear positioning as well (such as for a plotter.)
With a conventional motor without additional feedback the controller never "knows" where the rotation is. With a stepper motor, the controller provides pulses to its various windings which make it rotate a specific nubmer of degrees so, the controller "knows" exactly where the rotation is at any time.
As aNaRKi suggested, the controller may think it "knows" where it is at times (based on the number of pulses it has sent to the stepper motor, but if the stepper motor missed a pulse or got stuck, there is no "knowing" for sure its rotation. This can be overcome with additional components such as encoders to provide feedback to their controller as to the actual location.
There is also more to positioning than mentioned here, such as establishing a starting or known position to begin counting pulses from for positioning, etc.
Hopefully this will help.

Another use of a stepper motor is holding a position. Both coils of a stepper can be powered causing the stepper to stop and holds it position.
Steppers are used anywhere where there is a need to have motor feedback: such as in a robot. The bad part about using a stepper is if it ever "stalls" (gets a pulse but doesn’t move). Then you loose the entire purpose of knowing where the motor is.

Whether we want to let it out or not, motors can be discovered all over in our regular lives; they only have a tendency to be covered up. Motors are available in autos, printers, PCs, clothes washers, electric razors, and substantially more.
In any case, there are various individuals (which as of not long ago included myself) that would be dubious of how to make an engine run on the off chance that they were given one. In this way, how about we learn something today. How about we figure out how to utilize a stepper motors!

Motor Control Applications - Stepper Motor
Stepper motors are inexpensive and rugged because they have fewer mechanical parts. They are brushless, easy to position, and are commonly used in automation systems, although they are small low power devices as compared to other motors...

Hi.
Stepper motors are motors which can be configured to turn/step at a very precise unit. They are commonly used on applications that require accurate timing. (ex. 90 degrees per step which is equivalent to 4 steps per complete rotation)
It is very much different to other motors because aside from being able to run it in two directions (clockwise/counter clockwise), it can also be configured to stop instantly.
