What’s an Induction Motor?
An induction electric motor or asynchronous motor is an AC electric engine in which the electric current in the rotor had a need to generate torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
Working Basic principle of Induction Motor
We have to give dual excitation to create a DC engine to rotate. In the DC electric motor, we give 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 learn how an induction motor 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 stated in the stator because of the stream of current in the coil. The rotor winding is so 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 current through the rotor coils flows, another flux gets generated in the rotor. There are two fluxes, one is usually stator flux, and another is certainly rotor flux. The rotor flux will become lagging according of the stator flux. Due to that, the rotor will feel a torque which can make the rotor to rotate in direction of the rotating magnetic field. This is actually the working basic 
principle of both one and three phase induction motors.
Types of Induction Motors
The types of induction ac motor motors can be classified depending on whether they are a solitary phase or three phase induction motor.
Single Phase Induction Motor
The types of solitary 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 isn’t a self-starting engine, and that the three-phase induction motor is self-starting. So what is a self-starting motor?
When the motor starts running automatically with no external force put on the machine, then the motor is referred to as ‘self-starting’. For example, we see that when we placed on the switch the enthusiast starts to rotate instantly, so it can be a self-starting machine. Point to be noted that enthusiast used in home home appliances is an individual phase induction electric motor which is inherently not really self-starting. How? Will a question arise concerning how it operates? We will discuss it now.
