The term, "stator" is derived from the word stationary. 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.
Beside this, what is the difference between a rotor and a motor?
A generator makes electricity, a motor is electric powered (an electric motor on a fan the motor drives the blades), and the rotor is the center rotating component of the electric motor or generator. The body of the motor or the machine is stator. As the name suggests it is the stationary part of the machine.
What does the stator do in a generator?
The generator converts mechanical power developed by the steam turbine to electrical power. The generator consists of two main parts - the stator and the rotor. The winding is formed by connecting the stator bars to make a balanced three-phase lap type winding.
