What is an Induction Motor?
An induction engine 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.
Working Basic principle of Induction Motor
We need to give dual excitation to produce a DC engine to rotate. In the DC electric motor, we give one supply to the stator and another to the rotor through brush arrangement. However in induction engine, we give only 1 supply, so it is interesting to learn how an induction engine works. It is basic, from the name itself we can understand that right here, the induction procedure is involved. When we supply the supply to the stator winding, a magnetic flux gets produced in the stator due to the circulation of current in the coil. The rotor winding is so 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, according to Faraday’s regulation of electromagnetic induction, the current will start moving through the coil of the rotor. When the current through the rotor coils flows, another flux gets produced in the rotor. Now there are two fluxes, one is usually stator flux, and another is usually rotor flux. The rotor flux will be lagging according of the stator flux. Because of that, the rotor will feel a torque which can make the rotor to rotate in direction of the rotating magnetic field. This is the working principle of both solitary and three phase induction motors.
Types of Induction Motors
The types of induction motors can be classified depending on if they are a one phase or three phase induction engine.

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

Split Phase Induction Motor
Capacitor Start Induction Motor
Capacitor Start 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 over that the single-phase induction motor is not a self-starting motor, and that the three-phase induction engine is self-starting. So what is a self-starting motor?

When the engine starts running automatically without any external force applied to the machine, then the motor is known as ‘self-starting’. For instance, we see that whenever we put on the change the enthusiast starts to rotate ac motor immediately, so it is a self-starting machine. Point to be noted that lover used in home devices is an individual phase induction motor which is usually inherently not self-starting. How? Really does a question arise as to how it works? We will discuss it at this point.
