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 had a need to create torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
Working Principle of Induction Motor
We have to give dual excitation to make 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 one supply, so that it is interesting to learn how an induction motor works. It is simple, from the name ac motor itself we are able to understand that right here, the induction process is involved. When we give 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 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 legislation 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 produced in the rotor. There are two fluxes, one can be 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 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 stage induction motors.
Types of Induction Motors
The types of induction motors could be classified depending on if they are a single 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 is not a self-starting engine, and that the three-phase induction electric motor is self-starting. So what is a self-starting electric motor?
When the motor starts running automatically with no external force put on the machine, then your motor is known as ‘self-starting’. For instance, we see that when we put on the switch the lover starts to rotate automatically, so it is definitely a self-starting machine. Indicate be noted that enthusiast used in home appliances is a single phase induction engine which is certainly inherently not really self-starting. How? Does a question arise as to how it works? We will discuss it now.
