What’s an Induction Motor?
An induction motor or asynchronous motor is an AC electric motor in which the electric energy in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
ac motor working Theory of Induction Motor
We have to give dual excitation to create a DC electric motor to rotate. In the DC motor, we give one supply to the stator and another to the rotor through brush set up. But in induction engine, we give only 1 supply, so it is interesting to know how an induction electric motor works. It is basic, from the name itself we can understand that right here, the induction process is involved. When we supply the supply to the stator winding, a magnetic flux gets stated in the stator because of the movement of current in the coil. The rotor winding is indeed arranged that every coil becomes short-circuited.

The flux from the stator cuts the short-circuited coil in the rotor. As the rotor coils are short-circuited, in accordance to Faraday’s law of electromagnetic induction, the existing will start flowing through the coil of the rotor. When the existing through the rotor coils flows, another flux gets generated in the rotor. There are two fluxes, one is definitely stator flux, and another is certainly rotor flux. The rotor flux will become lagging according of the stator flux. Due to that, the rotor will feel a torque which can make the rotor to rotate in the direction of the rotating magnetic field. This is the working theory of both one and three stage induction motors.
Types of Induction Motors
The types of induction motors can be classified depending on whether they are a solitary phase or three phase induction electric motor.

Single Phase Induction Motor
The types of one phase induction motors include:

Split Phase Induction Motor
Capacitor Start Induction Motor
Capacitor Begin and Capacitor Operate Induction Motor
Shaded Pole Induction Motor
Three Phase Induction Motor
The types of three phase induction motors include:

Squirrel Cage Induction Motor
Slip Ring Induction Motor
We have already mentioned above that the single-phase induction motor isn’t a self-starting engine, and that the three-phase induction engine is self-starting. Just what exactly is a self-starting engine?

When the engine starts running automatically without any external force put on the machine, then your motor is referred to as ‘self-starting’. For example, we see that whenever we placed on the change the lover starts to rotate immediately, so it is definitely a self-starting machine. Point to be noted that fan used in home devices is a single phase induction electric motor which can be inherently not really self-starting. How? Really does a question arise concerning how it operates? We will discuss it today.
