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...
Michele Bucci I feel ya. My teacher didn’t even bother to come to half our classes, and I legit did not even know we had this topic for tomorrow’s test. College sure is fun.
Feel you, across the world.
Seems like some educators all around the world aren't working the way they should. Din know it's a problem there too.
Yep it is bad. Last test tomorrow for tech this year. Glad the teacher is moving to another school. I always have to do my own education (besides in the class) in order not look like a idiot in the field.
🤣😂🤣😂
Complicated things made simple using such an extraordinary animation effects. It was a very helpful video. Thank you very much !!!
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
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.
This is awesome. All animated and visualised points.Thank you.
It's amazing how a great video like this with such painstaking visualisation can be uploaded for free on TH-cam, and still people complaining because of a missing definite article ('the'). Sense of entitlement.
Really good explanation with good visuals. Understood it clearly.
These videos are really helpful. They should have more views!
This video was really helpful!! Thank you.
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.
Or centrifugal switch
Great Video . Really supplemented my awesome teachers uber fun lessons. Gerry Rocks!!!!
Thank you for your wonderful animation!!!!!!........was really helpful
I feel like young student in your classroom at
the age 63. Thanks Sir.
The simplest explanation. Thank you all.
Very good graphics showing net magnetic field of rotor squirrel cage. Thank you
all the videos are amazing!!! keep up the good work! life saver!
+priyam Gupta Thank you :)
+Dave batista to help create initial rotation

Dave batista
Priyam Gupta.. Ya
LOVE U
Thanks- this helped me figure out a problem with my pump motor
excellent job bro
all ur videos are good to understand
i think u revolution will be possible
you're a life saver , THANKS
what a great channel this is!
thank you so much it was easy to learn with your video. :)
Phantastic explanation
Awesome visualisation.... Better than any class that would take 1 hour to explain this 4 min stuff..
This is exactly what I needed 👍
So well made
this is really helping, nice video.
very nice explanation,Thank You
Nice animation.. easy to understand
great tutor, many thanks!!!!!!!!!!!!!!!!!!!!!!!!!
Excellent video
Thanks for explaining so nicely
this is awesome. thanks so much...
Beautiful explaination
Awesome channel..❤️❤️❤️
Very helpful content..🔥🔥
I understood clearly. Thankyou sir
Awesome video
well done video. Thanks!!!
Keep it up with this type most Interesting videos for study of electric engineering
3d animation of any system is like imagination of our mind so nice imagination.....
These videos worth alot.......💯💯
Wish these vids to be added as reference in the syllabus
These videos made life of engineering students way easier.... We don't have to imaging anymore.
NICE VIDEO BY THE WAY!!!
god bless u.. splendid work..
Great visualisation
Awesome video 👏
Excellent explanation sir
very nice review, thank you
Very good explanation
Hey bro you are such a great video
Nice video bro
Unique is every videos,thanks
I appreciate the simplified sentence structure.
Superb explanation for ee engineering students
GOOD JOB BOSS...KEEP IT UP... UPLOAD MORE
simply superb 😃
Good Explaination
Awesome videos
Absolute masterpiece
thanks for explanation
Awesome Bro...Thanks
Superb sir
excellent,thanks
Just awesome 👍
Very good thank you
Nice one
Nice vidio sir ji
Wonderful
Thank uuuuh very muchhhh ❤❤🥰🥰🥰🥰🥰
I know how is the connection of this but for the sake of those who doesnt know it will be more helpfull if the uploader includes how is the connection between starting winding, running winding and capacitor.
thanks allot for this video.
excellent
Great video ,easy to understand
What do u use for making such videos
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
Yes it does increase the horse power but can also create more ampage causing the motor to over work and burn out it is a very fine line to work with
Aaron Melbourne you don't know much about motors did ya?
5 years later and you still got no response 😂

Should the magnetic field polarities shown at 0.55 time of the video be reversed according to the arrows current flow?
Thanks for this video, it was very informative. At 0:54, isn't North and South supposed to be the other way?
thank you very much.
The only part I don't understand is, once you put the rotating rotor inside the cage, why does it keep rotating and not eventually slow down. I understand the initial imbalance of torque, but once you turn off the auxiliary winding current this imbalance should fade should it not (similar to how if you push something it doesn't keep moving forever, eventually it slows). Eventually the torque due to that initial motion should fade and you should just be left with a net torque of zero??
I'm stuck in the exact same question, I can't understand why it don't slow down when initial rotation is applied
Amazing
Thank you
I want all this videos to explain details about basics and add some more topics in easier way
Thank you.
yes one neat trick I recently learned is that if your single phase induction motor is humming but not spinning, you can start it by hand, just twist the output shaft in either direction and watch it come to life, this is a dead giveaway that the starting capacitor is bad and needs to be replaced
thanks for your explaination it saves from reading 20 pages pdf
thanks and wecome to india
This is amazing! But could you please tell me why do the two sets of blue current flow in the opposite direction to each other at 1:50?
Thank you
PS.I was trying to apply Flemming's left hand rule but the two parameters , current and force, were initially unknown at the squirrel cage in the first place. So I can't solve the problem.
This is a case of current carrying conductor rotating in a magnetic field so instead you should be applying flemming's right hand rule.
Also at 1:51, you can see that the opp directions of the blue induced currents because of the corresponding current in the main winding shown beside it.
Thank u so much....😀
Thanks sir
Good graphics.
very excelant
Wow. That is great explanation.
Awesome
Thaks ENGINEERS for this beautiful world
Teri mki
awesome thnks
I have watched the video till the end hoping to find additional informations about the working of the centrifugal switch, in the end only its name was mentioned...no luck
Anyway nice video 👍
great video , sir can u upload video on power system
Nikola Tesla is one of the most underrated geniuses of all time. Many people are familiar with his name but most have no idea of his contributions to science and engineering.
Very nyc
Thankyou Sir
great!
