DC motor

Found a website on the construction and workings of a DC motor.  What helped me understand it a little more was how a DC motor is physically constructed with the theory involved as well.  I know now that the stator magnets, which use N and S poles, are actually what keep the shaft rotating when current is applied through the coils.  The coils, with current applied, create an electromagnetic field that reacts with the magnetic field of the stator magnets.  What can sidetrack me is the fact that the polarity of the coil magnets change from N to S and back again as they rotate inside the stator magnets, but also seems to be the basic operation of a DC motor.
