Closed type windings: In this type of winding there is a closed path around the armature or stator. Starting from any point, the winding path can be followed through all the turns and starting point can be reached. Such windings are used in DC machines.
Open windings: There is no closed path in the windings. Such windings are used in AC machines(star connected).
TYPES AND SHAPES OF WINDING WIRES:
The winding wires used in electrical motors are classified as follows.
1. Round Wires: It has thin and thick conductors and are used in semi-closed slot type motors and mush winding rotors. It is wounded in reels and available in Kilograms.
2. Rectangular straps: It is used in open type slot motors. These conductors are available as long straps in meters. They are used in the following places. a) Low voltage motor windings. b) Used as conductor in high current motor. c) Series field motor winding coils.
Commutator pitch: The distance between the two commutator segments to which the two ends of a coil are connected is called commutator pitch and is designated as yc and is measured in terms of commutator segments.

[@sanjeebkumarspeed]

Great work sir . Sir you make armature winding concept crystal clear to me ..Tq Sir Double layer winding video unavailable!!!!!

[@balasujithpotineni8184]

Hello sir, I think you said that if Yw

[@ramseyfernando3420]

you explain is very clear sir

[@jagannathdevotees8583]

Sure Sir...❣❣❣

[@jagathsurya8687]

sir can u please explain motor design constriants like electrical loading and specific magnetic loading ????

[@sibibalakrishnan1]

Brilliantly explained. This is a topic usually taught in the initial classes of electrical machines in engineering. Most students don't get it even after engineering.

[@gautamyadav5924]

First time in my life I UNDERSTAND BETTER SO MANY THANKS SIR

[@Rodderick45]

Excellent presentation and thank you for presenting it in English language. I follow many videos on YOU TUBE from India in the field of Electrical, Electronics, computer, switch mode power supplies and although they are presented in Hindi, I still enjoy them. The on line classes from the Universities and other schools there in India are in English and very well presented. I am now a new subscriber and will be following all future presentations as well as your present ones. Thank you and keep up the good work.

[@PunitKumar-bc9cy]

PiSquare Academy is a new way of study. Thank you sekhar sir for explaining winding in a new and unique way.

[@durgeshzope5142]

I searched long time for practical study of windings in youtube but you Help me lot and clear my concept clearly😊

[@sushantaization]

Thank you so much Sir. You are really doing a great work. Please keep it up. Winding is the most confused topic for an Electrical Engineer . yet you make us understand it so well. The way you used 3D models to help us visualize it ; is the best way to teach it. Please continue the hard work. It's a request Sir.

[@madhevanramalingam4089]

In this whole world you are the only one guy to teach this winding beautifully luv u guys😍

[@jatinsharma782]

You are very hardworking person... Keep doing this lecture is fantabulous

[@prashanthjha6932]

This is an extraordinary lecture. May God bless you and I sincerely hope you help millions of students like me sir.

[@muhammadrafiqulislamkhan6994]

Though I do not understand the whole lecture but I thing this simplest lecture about armeture windings. And I love to see idea of using slots on the wall . It helps lot to me to understand repeating watch this video. Thanks to you. I would request with the lecture teacher shows practical process to wind coil it more easier for his viewers and students. And finally, I hope to make more videos next.

[@saumodipdas3624]

superb content sir. Really cleared the concept that too less than 30mins!!!!!!

[@subhankarmukherjee8092]

Sir plz upload the concept of circle diagram of Induction Motor

[@bhuvanakrishna1960]

induction motor performance can be seen with circle diagram , if you want to learn circle diagram then there are easy steps . first read the working of induction motor second enlist all the components / parameters are useful for working / running of the motor third now start doing the graphical representation step by step from referance axix , do first understand the meaning of property being projected via X axis and Y axis . fourth not sync with the theory and the actual diagram with proper notation for the induction motor .

[@shivammalviya1718]

Thank you so much sir 👏👏👏👏👏

[@husnasumi5317]

Thank you sir Plzz add PDF ,including short note on content including in this video. Which help to us better

[@vijaybaskaran6397]

Shekar sir make some videos about power system faults and clearing method

[@namanmange5324]

please make lecture on single pahse induction motor or fan winding

[@rameshkrishnanilayam6095]

Perfectly understand

[@venkatagopitirumalapuri4574]

Sir... Can u make a video lecture on cable sizing for induction motors.... It is very help full for us

[@nimalsandunsiri4024]

Good explain thank you

[@haftomgebrehiwet1911]

differenc between coil and turn

[@balajipandian2147]

thanks bro.... another nice one from you...

[@senthilnathan1789]

Hi What is the purpose or effect of progressive and retrogressive windings in lap and wave

[@kronosdarkangel5290]

Do the string or wire is linear? Or it should go back to the 1st slot until it creates turns before it will proceed to the next slot?

[@shubhamkumar-di7ry]

Well done sir

[@rayismooppan459]

Useful video sir

[@satyammishra4397]

i am ur junoir from nitdgp ...u r mtech in machines so i hope u know the legendry S Ghosh sir ..

[@premtours]

please tell me about torque speed characteristics of 3 phase induction motor

[@shubhamkumar-di7ry]

Sir u are great

[@kuntaldutta959]

Sir please make a lecture on armature winding - 1) open winding and closed winding

[@examcafe2649]

In case of a 4 pole D.C. generator provided with a 2- layer lap winding with 16 coils, the pole pitch will be? The answer of this question is given in the book is 8. Is this correct or not. Pls give the right ans

[@kronosdarkangel5290]

I am still confused on the winding setup of an 3 phase alternator sir... In which a coil with multiple turns is inserted on 1st and 6th slot... so from 1st slot then to 6th slot and back to 1st slot until it creates multiple turns and so on until it will become 3 phase alternator can you please explain it and please include how the electrons flows due to pole pitch? And I thought that the more poles the better since it only needs low rpm to generate high frequency

[@manishchetiwal1811]

Good explanation

[@AshrafulIslam-bz2ui]

Watching from BANGLADESH

[@keerthanaroy4102]

AMAZINGLY THOUGHT THANKS A TON :-))))))

[@manjunathachari5269]

Sir explain the need of dummy coils and Equalizer rings

Hi sir Ac current means polarity is changes continuously then why when check by tester in socket tester only light up in phase not in neutral?

[@wingedbull1257]

@PiSquare Academy I have two N52 Magnets Size 2"L x 1"W x 3/8"H and Magnet wire Diameter 0.0367" 18Awg, I will have One Magnet face North and other South But I need to make One Magnet wire Coil that both Magnets rotating 360 degrees in center of One Coil to produce at least 14 Volt and light up 150 watts light bulb, How many turns of magnet wire I need to do or have to produce what i'm looking for the out put. I look forward to your reply
