You might have seen that in order to start a high power rating induction motor, a starting technique called star-delta is used. In this video, we will understand why a star-delta starter is needed, and how it is accomplished practically with help of animation.

High speed rotation effect in 3D visualization of fan.

This video gives an elaborated explanation on working of Alternators/ AC Generators with help of animation. Alternators are also referred as Synchronous generators. Along with construction details of generator, functions of slip rings, armature coils, Automatic Voltage regulator (AVR) and pole core are also well explained here.

The working of a DC motor is well explained in this video with the help of animation. Construction details of DC Motor, Shunt & Series motor, concept of back EMF are also explained in this video.

This demonstration explains the construction and functions of various parts in a three phase transformer visually.

How does an induction motor work Working of 3 Phase Induction motor is explained in this video with help of animation. They are the most commonly used electric motors. Here basic operation principle of an induction motor is introduced in a logical manner. Concepts of rotating magnetic field, synchronous speed and slip is well introduced in this video.
