Difference Between Stator and Rotor
Given Below is the Difference Between Stator and Rotor
Basis |
Stator |
Rotor |
---|---|---|
Movement |
Stationary part of a motor. |
Rotating part of the motor. |
Components |
Three main parts of stator are:
|
Three main parts of rotor are:
|
Construction |
Generally made of iron or steel. |
Made of laminated iron or steel. |
Design |
Usually designed to be robust and durable. |
Protects the internal parts of machine from external damage. |
Maintenance |
Requires less maintenance. |
Requires more maintenance. |
Location |
Connected to shaft of machine. |
Connected to stationary frame of machine. |
Cooling |
Due to stationary nature, stators are easier to cool. |
Comparatively, not easy to cool rotor. |
Supply |
Generally receives three phase AC supply. |
Depends on type of motor used:
|
Friction Loss |
Experiences minimal friction loss due to stationary nature of stator. |
Experiences friction in bearings due to rotatory nature of rotor. |
Winding arrangement |
Complex winding arrangement. |
Simpler winding arrangement. |
What is Rotor?
Rotors are a fundamental part of electrical machines and play an important role in their operation. Rotor is the rotating part of an induction motor. It is connected to the mechanical load through the shaft. There are various designs of rotors available on the basis of application and type of machine, such as squirrel cage or wound type.
In this article we will go through the definition of the Rotor with its construction in detail with its diagram, we will also go through the classification of Rotors and difference between stator and rotor, At last we will conclude our article with some of its applications and FAQs.
