In the motors or generators, both the parts like rotor and stator play a key role. The main disparity between them is that the stator is an inactive part of the motor whereas the rotor is the rotator part.
The stator is the stationary component of electromagnetic circuits. In different configurations, stator may act as field magnets that interact with the rotor to create motion or as armatures that work with moving field coils on the rotor. They are generally permanent magnets or electromagnets that maintain field alignment with the latter being a field coil or winding.
The stator in AC motors consists of the core’s thin, steel laminations and the coils of insulated wire inserted into it, which are called windings and connected directly to the power source. When current is applied, the two together become an electromagnet. In DC motors, the stator carries both the field windings and the poles, which constitute the magnetic circuit with the rotor. Field windings in that case may be either windings or permanent magnets on the stator; the poles house the field winding, with the number determined by voltage and current.
The stator being a stationary part of a rotary system can be found in electrical generators, electric motors, sirens, mud motors or biological rotors. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid power devices, the stator guides the flow of fluid to or from the rotating part of the system.
The rotor is a general term for the main spinning part of an electrical machine and derived from the word ‘’rotating’’. Therefore a rotor can be described as a moving component of an electromagnetic system i.e alternator, electric generator or electric motor. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor’s axis.
There are different types of rotors (rotating parts). They include Squirrel cage, Slip ring, air type, wound type and salient pole type.
