No one explain like you in my whole life. great work🙏
Happy to help
@@EngineeringMindset you’re amazing, Paul!
Keep up the amazing educational content 👍🏻
agree with you. i spend my time in degree and still confuse sometimes but this guy make me understand under the video duration. Great work bro!
Explain*
THAT WAS GOOD...I AGREE
I was a motor rewinder in my days in the NAVY. Your videos remind my of the tedious times I spent battling +50hp motors during less than ideal sea states.
I'm currently reading a textbook on electromechanical instruments--as a complete newby who's also having to teach himself the math as he goes along just to try and comprehend what I'm seeing at all.
A few pages from where I'm presently at, I've seen the diagrams for delta and star configurations.
Point being . . . .this video--and others you made--is really helping me out!
Thanks!

("Et Al" sat this one out.)
It’s 1 video per month but it’s always worth the wait. Great content as always!
Trying to make more per month, the animations take so long though
@@EngineeringMindset Sir: We are thankful for the one a month.
Wonderful informative as usual.
Totally understand the difficulties involved in making such high quality content. Respect to the team!
Wow.. thank you for this simple direct explanation.. now I get it!!👍
So much work in making this video! Thank you for taking the time. Very well done.
Glad you enjoyed it!
Agree, many hours must go into making these.
What an clear description to understand. Thanks 🙏
These videos are more than worth a few bucks. You've got people paying themselves into debt for this knowledge. I was one of em.
Appreciation and thanks Sir, for such a great and good explanation, I never had such experience in my ITI Technical College when i was performing, thanks once again, keep up the good work, God bless you and your family.
Took me five seconds to get what I needed. Remind me that I owe you one! 🤩
Thanks for sharing it with us. Very educative
Brilliant explanation, thank you!
Thanks a lot for great explanations. Please make a video for VFD repairing lab setup( what type of Instrument need for VFD repairing)
I'm a amateur when it comes to electricity, learned so much.
big thanks for you paul, salute!
Thank you, God bless you
Great knowledge of electric motors
Hey @The Engineering Mindset,
would you care to explain why at minute 4:36 you say that you can add a neutral wire if needed?
Is this a choice you can make?
This channel is a world championship, it is a pity that it is not in Polish.🙋♂️👍👏
Very useful content with great graphic work soo accurate... Great work sir.. God bless you all ♥️✌️😊
Thank you
Nice visuals.
Very clear.
The most clear and neat explaination I've ever seen, continious subscribtion lol
Very glad to hear you enjoy the content

99% good explanation 👏
Super helpful!!! 😊
like clockwork ,love it !
Nice job.🔝content👏❤️👍🏻
Great work 🥳🥳🥳 Thank you 💜💜💜
GOOD explaining video .
Thank you for very informative video. Will be good for me for testing old find motors before dismantling for copper and other metals in my channel
Very interesting so thank you for this. It would be interesting to relate this back to the usage for each configuration - I assume delta is used for higher horsepower motors but where does the cutover occur? Cheers
Here you go th-cam.com/video/h89TTwlNnpY/w-d-xo.html
@@EngineeringMindset That was helpful so thanks. I didn't pick initially that you can use the star configuration as a starting point for the delta to reduce inrush current - I thought that they just alternatives. Cheers from Oz.
Good explanation
Great work..👍🏻👍🏻👍🏻
Thank you sir 👍🏻❤️
Thank you 😊
Good job
Good video graphics editor
Thank you so much
Thanks alot brother. Yoi are amazing
Good teacher
Thanks 🙋🏻♂️
I used to teach a class on this subject. It was very hard to keep students engaged, as the information is somewhat dry. Having physical examples is the key to learning this subject.
As a student, I agree.
I agree. Don't think I took one bit of notice in college to this ans now I'm here trying to learn after applying for a maintenence job😂
I love to learn about ac electric machines😋😋
Job well done
Thank you for the explanation and difference between the "Y" and the "DELTA" connections. When would the "Y" connection and the "DELTA" connection be used?
You would wire the motor according to the electrical system you are using( houses are mostly Y). The voltage of the system, and the number of leads on a motor. This wiring is just a 6 lead wiring. examples of other wiring
annawiringdiagram.com/wp-content/uploads/2019/02/3-phase-6-lead-motor-wiring-diagram-wiring-diagram-3-phase-6-lead-motor-wiring-diagram.jpg
@@SACalkins1 Thank you.
There are systems that start in the Wye or Star configuration because of the massive amp draw is reduced, then using some timers and three contactors will set the configuration to Delta because the motor can run faster.
Awesome content
How will the voltage and current differ between delta and star, if the motor is used as a generator?
One question sir is a six 6lead motor can run on hight and low voltage as 400 and 230 valts from star or delta connection which one is hight or low voltage as 400 or 230 volts thanks
good sir, since star connection is less amps, so is it advisable to run the motor in star conncetion , and then why it is required to start motor in star and run in delta ?, please clear my doubts.
Do you always need 2 sets of coils per phase across from each other (like in your video)? Or would it be possible to use only one coil per phase (so the current enters the coil in U1 and directly goes to U2 at the end of the coil)?
Then it will produce low torque
Thank you
Thanksអគុណបង👏👍😍
Awesome!
Thank u 💓
I would love be a electromechanic engineer 😍😋
Great job :)
Thanks! 😄
nice video bro
5.29, you said correctly 11.5 Amps but wrote 1.5. Great video by the way.
11.5 is written on screen. The two 1's are close together though so it does look a bit like 1.5
@ the engineering mindset , can you explain how and why some 3phase motors are wired up to be star delta aka start in star but run in delta please thanks in advance .
Regards Lindsay

Great 👏
Please put a video on working of computer's Switch Mode Power Supply
Can you do a series of videos on SCR's/Thyristors please.
As I understand them they are similar a fast "relay" in a small scale.
An SCR is a device that conduct electricity in one direction normally for DC circuits, whereas a Triac conducts in both directions. When gate voltage is applied, the device begins to conduct and the gate voltage can be removed. As long as there is voltage across the anodes. Once the voltage on the anodes reaches zero, the device shuts off and needs to be retriggerd again. Usually a triac also is used with a diac on its gate. A diac is a dual is a dual diode that can have an Resistor/capacitor combination on one end that will delay the turn on of the DIAC/TRIAC combo withing a given time period within the sine wave. This is normally used for light dimmers
Check out NEW resistor video, everything covered! ➡️ th-cam.com/video/DYcLFHgVCn0/w-d-xo.html
Do You mean by using less current and voltage for the star connection that will give us less voltage and current as output?
If the star or delta connection is an option in any 3-phase motor, does this mean you can use either configuration in order to get higher or lower power output? This seems a bit odd to me, as I would have expected the motor design to be optimised for one or the other (but I am not an electrical engineer).
@@ciberiada01 Interesting. Since I posted that comment I saw another video about the star/delta switching systems that you mentioned. This apparently is intended to limit the huge inrush current that induction motors draw when initially powered (which will be lower with a star connection). Once it's up to speed it can be switched to delta for maximum power, without such a big current surge. Maybe that's the main reason for having the option available. I'm not sure I understand why a motor would be designed only for star connection though.
How can to phases be connected together with out a short circuit thanks.
Very good explanation but you left the ending Hanging. You could end like this "Since the Star Connection uses less current thus Motor Connections should be in Star?" or "Since Delta connections produce higher voltage of 400 running of Motors is on Delta?" .. makes better sense?
Thanx keep on
Thumbs up 👍
Tks u
Hello, I want you to make a video about Dynamo 100 kW 3 phase generator
អគុណបងthank you
Cool !
Thanks
What happens when you have a motor wired for delta but have wye service? Is there a possibility of burning the motor?
Next needs to be star delta starters and the time delay switching over. I thought it was super neat when someone explained what it was.
Here you go th-cam.com/video/h89TTwlNnpY/w-d-xo.html
Is there any connection between three phase motor shown here and three phase permanent generator used in wind turbines? Is there star/delta connection in permanent magnet generator?
Seen our new - How wind turbines work video? link: th-cam.com/video/Hf875eOVrVI/w-d-xo.html
thanks
too good
Greetings to you. I want to ask, can I translate your video into Russian and put it on TH-cam with a link to your channel?
No, that would breach our copyright
@@EngineeringMindset Thanks for the reply.
square root can be interpreted as equal contribution to each other. multiplication means contibution of one dimension for each unit of another dimension. Equal contribution, or a joint.
So the purpose of the 2 terminals is basically to supply a path for current to flow back. So the windings have an impedance, otherwise you would effectively be shorting out the phases in the terminal box? What material are the windings made out of and to what size? Because to add a high impedance, coil lots of cable and still have them sized appropriately to take the current, doesn’t make sense in my head lol. If youre feeding a motor with say a 16mm cable @ say, 0.3ohms, and you need to carry that same current, wind it around and have I don’t know, 100ohms, w-how? Lol
Super
What about the load. Both connection can work on same load?
Nice video. But please upload subtitle.
Good Sir......my request Indonesia subtitle....😁
The star version uses less voltage and less current. Repeat after me, 100 times. On a three phase motor the
star version uses less voltage and less current. Thank you very much.
Informative.
upload for motor rewinding
👍 mulțumim
We don't have terminal boards inside the connection box on three phsse motors in America, just nine wires brought out from the internal part of the motor into the connection box located on the motor external. All nine wires hang individually loose within the connection box and are NOT connected when bought from the motor vendor. Six of the nine wires have their own number designation attached to them. The designation ranges from the number 4 thru the number 9. Each of the remaining three wires have their own designation as well. Those designations are T1, T2, and T3. Sometimes T1, T2, and T3 may just be labeled as 1, 2, and 3, not having the letter "T" attached. Again, the nine wires are connected in the field, inside of whatever piece of equipment/system of which they are a part. Three phase motors are built as multi-voltage motors in America. The two voltages are 230 volts 3 phase and 460 volts three phase. How the nine wires are connected is dictated by which voltage listed above is going to be applied to the motor AND whether the connections will be configured as Delta or Wye (Star). The connections within the motor connection box are all made using wire nuts and approved electrical tape, NO terminal boards. Also, the connection box is informally referred to as a "peckerhead" which is just jargon used in the skilled trades.
How are 7,8, and 9 wired inside the motor. I am trying to visualize the inside of the motor. I understand 1 and 4 are 2 windings, 2 and 5 are 2 windings, and 3 and 6 are 2 windings making a total of 6 windings in the motor but when 7,8,9 wires are popping out of the motor I don’t understand how they are wired inside the motor.
Thanks!
Thank you, Mario
Fun fact: the electrical terminal box is sometimes called a peckerhead. Haha ic
Brilliant😀
I wish this used US standard voltages and termination numbering as well.
