Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Stator & Rotor. There are two main types of electrical machines first one is AC machines such as ac generator and ac motor. Which are further divided into other types such as induction motor, single-phase induction motor, three-phase induction motor, synchronous motor, and introduction to synchronous generator, induction generator. The second type is the dc motor and generators. All these machines either ac or dc have main two parts which are stator and rotor. The basic difference between them is that stator is a static part and the rotor is a rotatory part of these machines.
The subparts of stator are core of stator, frame of a stator, and windings of stator. The stator frame provides supports to the core and protects the winding wounded from the external environment. In the core of stator rotating magnetic field flows that is generated due to input 3 phase supply. The rotor of machines is placed in the core of the stator. There are commonly used types of the rotor are squirrel cage and wound rotor. The supply given at the stator induces a magnetic field in the stator which like with the core of the rotor to generates emf int he rotor. In today’s post, we will have a detailed look at both rotor and stator and find their differences. So let’s get started with the Difference Between Stator & Rotor.
Difference Between Stator & Rotor
- The static part of electric machines is called stator in this part field winding is wound and input supply is given in the case of the motor.
- There are 3 main parts of the stator which are the outer frame, stator core, and stator winding.
- At stator large insulation is needed than the rotor.
- The amount of frictional losses at stator is large.
- The cooling process of the stator is easy.
- Energy transmits from the stator and comes to the stator to the rotating part of machines that is the rotor.
- In the case of motors rotting magnetic field is produced at stator that is given to the rotor windings and emf induced at motor work.
- While in generator stator used to the conversion of the field to current
- At stator, ac supply is given.
- The winding wound on the stator is complicated than the rotor windings.
- Stator cover the inner part of machines and also saves from damage
- Stator can be permanetn magnes or electromenaget
- In electromagne,t the field coils is used to make electromagnet
- The rotatory portion of an electric machine is called the rotor.
- There are 2 main parts of the rotor first in the winding of the rotor and the second one is the core of the rotor.
- The dc supply is given at the stator.
- There are different types of rotor like squirrel cages rotor, wound rotor salient pole rotor
- The configuration of windings at the rotor is easy than the stator.
- At the rotor, less insulation is needed.
- The cooling process of the rotor is difficult as compared to the stator.
- In the case of 3 phase induction, motor ac given to the stator and flux induces in the rotor.
- Due to flux field is generated and current passing the rotor.
- Squirrel cage rotor speed is less the speed of field at the stator.
- wound rotor has the constant value off speed and operate at less currnet
That all about the difference between rotor and stator if you have any query ask in the comments. I tried my level best to make simple this post for you. I hope you enjoyed this tutorial. Have a good day. see you in the next post.
