Slip ring Induction Motor, How it works ?

Induction motors have been ruling the industrial world for many decades. In the induction motors used in lift and hoists, you will see a type of rotor called a slip ring rotor, whereas in most of the other applications you will see a simpler, squirrel cage type of rotor. Why are there two different designs of rotor construction for induction motors? We will explore this in the video.




How does an Induction Motor work ?

The invention of induction motors permanently altered the course of human civilization. This hundred-year-old motor—invented by the great scientist Nikola Tesla—is the most common motor type, even today. In fact, about 50 percent of global electric power consumption is due to induction motors. Let’s get into the workings of induction motors, or more specifically, into Nikola Tesla’s genius thinking.




DC Motor - 3 Coil, How it works ?

The three-coil DC motor is one of the most ingenious inventions in the electrical world. Its construction is so simple and unique that understanding the working principles behind it will be a real fun!



Understanding STAR-DELTA Starter !

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.




How does a Stepper Motor work ?

Stepper motors are the one of the most widely used motor type due to its simplicity and position control capability. This video gives a step-by-step explanation of variable reluctance stepper motor and hybrid stepper motor with help of animation. It also explains the concept of half stepping.

Single Phase Induction Motor, How it works ?
Working of Single phase induction motors is explained in this video with help of animation.
When only single power phase is available, single phase motors are the natural choice out of wide variety of electric motors. In this video concept of double revolving field theory, main winding, auxiliary winding, and the way motor is made self start is explained in detailed way.



How do Universal Motors work ?
The working principle of Universal motors is explained in this video with the help of animation. They are capable to run under both the A.C and D.C power sources.


Working of Synchronous Motor
Working of synchronous motor is elaborately explained in this video animation. This video explains how constant speed characteristics of synchronous motor is achieved, and why they are not self starting and use of damper winding to make them self start. Use of Synchronous motor as synchronous condenser is also explained here.
