Working of Rotor
Given Below is the working of the Rotor
- A suitable supply is given to the stator windings. This creates a rotating magnetic field, which rotates around the stator at synchronous speed (Ns).
- The rotating field sweeps past through the air gap between rotor and stator, cutting through the rotor conductors, which are stationary.
- Due to relative speed between rotating flux and stationary rotor, Electromotive force (EMF) is induced in the rotor conductors.
- This induced emf in rotor, leads to torque generation in the rotor.
- Depending on the type of electrical machine used (motor or generator), energy conversion process takes place. For example, in motor electrical energy gets converted into mechanical energy whereas in a generator the mechanical energy is converted to electrical energy.
- As the rotor circuit is short-circuited (in case of Squirrel Cage rotors) or externally wounded (in case of Wound Type rotors), current starts flowing in the rotor conductors.
- The synchronization of rotor with the stator’s rotating magnetic field, induces currents in the rotor and generates torque.
- Thus, the speed of rotor is maintained along with synchronization of stator’s field.
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.
