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.

The only sad part is that a free video on youtube is more effective than the lessons at the college that i'm paying for...

Complicated things made simple using such an extraordinary animation effects. It was a very helpful video. Thank you very much !!!

[priyamgupta]

all the videos are amazing!!! keep up the good work! life saver!

[willnettles]

Thank you. Very informative and actually dramatic. A sort of Asperger's Tesla action video with a capacitor as the hero who arrives just in time. Nothing cooler than clear, concise and accurate information.

[riasatsakeeb]

it was very helpful. i see people are abusing because of the language and the speaking but it is really helpful for the non-native speakers and learners like us to understand these ambiguous topics while you explain these in simple English. thank you Learning Engineering. keep it up and ignore the English literature "GURUs" in the comment section

[zaidshaikh]

This is awesome. All animated and visualised points.Thank you.

[EclecticSceptic]

It's amazing how a great video like this with such painstaking visualisation can be uploaded for free on YouTube, and still people complaining because of a missing definite article ('the'). Sense of entitlement.

Not all single phase squirrel cage induction motors are like this, some use a start relay and start and run capacitors.The capacitors create a phantom phase to get the rotor to spin 360 otherwise you just get locked between the two phases, in other words all squirrel cage induction motors are really three phase, but when you only have single phase power you need capacitors to discharge voltage that induces current and gets the rotor to spin 360, once it's spinning you don't need the capacitor induced current, although you don't get the same horsepower out of a 1 phase motor as you would out of the exact same motor using three phases of power, so the motor is typically de-rated. For industrial applications that use 1 phase power and start under load like mechanical machinery or a water pump, your better off using a phase converter that takes 1phase and converts it to 3phase.

3d animation of any system is like imagination of our mind so nice

[Proudman]

The simplest explanation. Thank you all.

[sunnyzaman]

Awesome visualisation.... Better than any class that would take 1 hour to explain this 4 min stuff..

[dennisjohnson]

Thanks- this helped me figure out a problem with my pump motor

[rajumani]

I feel like young student in your classroom at
the age 63. Thanks Sir.

[Landrew]

I appreciate the simplified sentence structure.

[TheDipankarrai]

These videos made life of engineering students way easier.... We don't have to imaging anymore.

[gerrysherk]

Great Video . Really supplemented my awesome teachers uber fun lessons. Gerry Rocks!!!!

Annu Aparajita Adding a capacitor changes the phase angle and hence causes difference in the field produced. This will lead to increasing the force for one and decreasing for other

[rohnsteve]

Wish these vids to be added as reference in the syllabus

[suryavishwanath]

i didnt understand the capacitor part for the self starting...if the auxiliary winding produces 2 fields rotating in the opposite directions, and if it cancels out one of the
fields in the main winding, then it must cancel out the other one also right ?

Keep it up with this type most Interesting videos for study of electric engineering
