Induction Motor        Induction motor (asynchronous motor) is an AC motor in which the electrical current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.So their is no need of electrical connection to the rotor. Working Principle         In an induction motor the rotor does not receive power by conduction but by inductions is exactly the same way as the secondary of a two winding transformer receive its power from the primary.that is why such motor are known as induction motors.In other words we can say that an induction motor is a rotating transformer in which primary winding is stationary but the secondary is free to rotate.            If we consider supply voltage we have two types of induction motors. Single phase induction motor and three phase induction motor.Single phase induction motor is not self starting where as three p...
