What’s an Induction Motor?
An induction engine or asynchronous motor can be an AC electric electric motor in which the electric current in the rotor had a need to produce 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 electric motor to rotate. In the DC motor, we provide one supply to the stator and another to the rotor through brush arrangement. However in induction engine, we give only one supply, so it is interesting to learn how an induction motor works. It is simple, 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 stated in the stator due to the circulation 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, according to Faraday’s legislation of electromagnetic induction, the existing will start moving 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 usually stator flux, and another can be rotor flux. The rotor flux will become lagging in respect 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 actually the working basic principle of both single and three phase induction motors.
Types of Induction Motors
The types of induction motors could be classified depending on whether 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 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 already mentioned above that the single-stage induction motor is not a ac motor self-starting electric motor, and that the three-phase induction motor is self-starting. Just what exactly is a self-starting motor?

When the electric motor starts running automatically without any external force put on the machine, then the motor is referred to as ‘self-starting’. For example, we see that when we put on the change the enthusiast starts to rotate automatically, so it is usually a self-starting machine. Point to be noted that lover used in home devices is an individual phase induction engine which is definitely inherently not self-starting. How? Does a question arise concerning how it operates? We will discuss it today.
