What is an Induction Motor?
An induction engine or asynchronous motor can be an AC electric electric motor in which the electric energy in the rotor had a need to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
Working Theory of Induction Motor
We need to give dual excitation to create a DC electric motor to rotate. In the DC motor, we provide one supply to the stator and another to the rotor through brush set up. However in induction electric motor, we give only 1 supply, so that it is interesting to know how an induction engine works. It is basic, from the name itself we can understand that here, the induction procedure is ac motor involved. When we supply the supply to the stator winding, a magnetic flux gets produced in the stator because of the flow of current in the coil. The rotor winding is indeed arranged that all 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. Now there are two fluxes, one is stator flux, and another is usually rotor flux. The rotor flux will become lagging according of the stator flux. Because of that, the rotor will feel a torque which will make the rotor to rotate in the direction of the rotating magnetic field. This is actually the working theory of both single and three phase induction motors.
Types of Induction Motors
The types of induction motors could be classified depending on if they are a solitary phase or three phase induction engine.

Single Phase Induction Motor
The types of single 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 mentioned previously over that the single-stage induction motor isn’t a self-starting electric motor, and that the three-phase induction electric motor is self-starting. So what is a self-starting electric motor?

When the electric motor starts running automatically without any external force put on the machine, then your motor is known as ‘self-starting’. For example, we see that whenever we put on the switch the enthusiast starts to rotate immediately, so it is a self-starting machine. Indicate be noted that enthusiast used in home appliances is a single phase induction electric motor which is certainly inherently not really self-starting. How? Will a question arise as to how it works? We will discuss it today.
