AC Motor or IM [ Part - 1 ]

What is AC motor or induction motor?

 

In general, the stator of an induction motor has three phase windings. The poles created by this winding are always paired such as: 2 poles, 4 poles, 6 poles etc.

 

The stator is supplied with a three phase AC current which causes current to flow and creates a rotating magnetic field which rotates at synchronous speed and cuts the conductor in the middle of the motor resulting in EMF detection in the rotor conductor under Farad's electro-magnetic induction principle.

As the current flows because of this brought about electric powered pressure, rotation is generated inside the rotor in order that the rotor begins rotating within the identical direction as the magnetic force line inside the stator. This motor is referred to as induction motor based on the principle of induction.
