The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. It also consists of a group of electro-magnets arranged around a cylinder, with the poles facing toward the stator poles. The rotor is located inside the stator and is mounted on the AC motor's shaft. The term rotor is derived from the word rotating. The rotor then is the rotating part of the AC motor. The objective of these motor components is to make the rotor rotate which in turn will rotate the motor shaft.
As can be seen in the above picture, the desktop hard drive consists of the following components: the head actuator, read/write actuator arm, read/write head, spindle, and platter. On the back of a hard drive is a circuit board called the disk controller.
