Working of an induction motor

The invention of induction motors permanently altered the course of human civilization. This hundred-year-old motor—invented by the . An easy-to-understand explanation of how real-life, AC electric motors work using electromagnetic induction. Induction motors are the most commonly used electrical machines.

They are cheaper, more rugged and easier to maintain compared to other alternatives.

In contrast, the synchronous motor does not rely on slip-induction for operation and uses either permanent magnets, salient poles (having projecting magnetic poles), or an independently .

In case of three phase AC operation , most widely used motor is Three phase induction motor as this type of motor does not require any starting device or we can say they are self starting induction motor.

This is the basic principle of how induction motors work. Click the above link to complete the free Automation Training which c. An induction or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is induced by electromagnetic. A rotating magnetic field in the stator is the first part of operation. In induction motors , this current comes from the rotor conductors.

This alternating flux revolves with synchronous speed. I previously covered how DC motors work , but AC induction motors are actually much more useful for homemade machines such as bandsaws. The revolving flux is called as Rotating Magnetic Field (RMF). It was the wicked and insane genius Nikola Tesla who invented them.

There is an extensive article on induction motors , . Know about the working principles and design of A. Dragonfly Education is an education company, that is building proprietary education content for higher learning in technical streams. This video is taken from video. The main advantages of induction motors are. Help us to make future videos for you. They are easier to maintain, cheaper and got rugged construction.

Normally induction motor has two main parts which are stator and rotor. When the windings in the stator are energized it induces current.
