What is an Induction Motor?
An induction electric motor or asynchronous motor is an AC electric electric motor in which the electric energy in the rotor needed to generate torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
Working Principle of Induction Motor
We have to give double excitation to create a DC motor to rotate. In the DC motor, we give one supply to the stator and another to the rotor through brush arrangement. But in induction electric motor, we give only one supply, so that it is interesting to learn how an induction engine works. It is basic, from the name itself we can understand that here, the induction procedure is involved. Whenever we supply the supply to the stator winding, a magnetic flux gets produced in the stator due to the movement of current in the coil. The rotor winding is indeed arranged that each 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 regulation of electromagnetic induction, the existing will start moving through the coil of the rotor. When the current through the rotor coils flows, another flux gets produced in the rotor. There are two fluxes, one is ac motor definitely stator flux, and another can be rotor flux. The rotor flux will be lagging in respect of the stator flux. Because of 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 solitary and three stage induction motors.
Types of Induction Motors
The types of induction motors can be classified depending on if they are a single phase or three phase induction motor.

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

Split Phase Induction Motor
Capacitor Start Induction Motor
Capacitor Start and Capacitor Run 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 above that the single-phase induction motor isn’t a self-starting electric motor, and that the three-phase induction engine is self-starting. Just what exactly is a self-starting motor?

When the motor starts running automatically with no external force put on the machine, then the motor is known as ‘self-starting’. For instance, we see that whenever we put on the switch the enthusiast starts to rotate instantly, so it is definitely a self-starting machine. Point to be noted that enthusiast used in home home appliances is an individual phase induction engine which is certainly inherently not really self-starting. How? Really does a question arise as to how it works? We will discuss it today.
