it is a motor that runs on direct current. like a battery. the current goes in one direction only, from negative to positive.
In North America our electric utility system is AC (alternating Current) meaning that the flow changes one way then the other (at 60 changes a second in fact) and the system for an AC motor must be a little different or else it wouldn't spin. it would change from clockwise to counter-clockwise 60 times a second.
so it's function is to spin (like any motor) but using the power from an electric source that does not alternate. Direct Current

DC motors are widely used to drive various equipment. The speed and torque produced in a DC motor depends on a variety of factors.
The DC motor has two basic parts: the rotating part that is called the armature, and the stationary part that includes coils of wire called the field coils. The stationary part is also called the stator.
