By far, one of the best explanations that I've seen & heard on a video! I've been an electrician for over 20 yrs, & thanks for explaining to everyone how it works!
For anyone reading a small clarification to the end. I know he mentioned it but to clarify when the contactor opens the aux contact opens as well which will keep the motor from restarting once you release the stop button. Also expect multiple aux contacts for things such as indicator lights and SCADA/DCS signals. Lastly there will often be a breaker at the very beginning directly in the three phase lines before any circuitry. This is for circuit protection as well as to kill power to allow for maintenance, repairs, and any other work.
Can’t thankyou enough, u made how the circuit excatly works crystal clear by drawing the power circuit and the control circuit together while explaining. Good job 👍
Excellent explanation, thank you. Everything is very clear--except I'm embarrassed to say it took me until 12:31 to realize that when I was hearing "coal", you were saying "coil". That makes *way* more sense! :) Posting in case anyone else was thrown by this.
Have a interview tomorrow and wanted to brush up on my electrical. It’s an E&I job and I’ve been doing strictly instruments for the last 3 years. Thank you for this video!
Nice concise explanation! I just wanted to add that the primary side of the step down transformer has 2 fuses as well. At least the motor controls I work on do. One other thing is it might be a good idea to label the contacts with the ANSI/IEEE device numbers as a lot of the prints we encounter identify the contacts with the device numbers. IE 49 contacts for the thermal overloads, and 42 contacts for the main contactor and aux contacts. I know you are probably just trying to do a simple explanation for newbies, but I figured I'd make this comment for those who are eager for the extra info. Nice Work! 👍
Thanks for the comment Kyle. You are 100% correct about the fuses, and the ANSI device names. I also did not include a main breaker or disconnect means for the main power section. You are correct about keeping it simple. My intent was to explain how the components work together rather than focus on the labeling/naming scheme. I believe the ANSI device names will probably be covered in later videos. Thanks for stopping by!
This stuff is awesome I recently started going to school for electricity, motor control circuits and programmable logic controllers are most interesting to me!
Very good video. Especially you can explain it from two wires circuit to three wires circuit. It’s easy for the beginner to understand it. But for one thing it is confused for the beginner . It is the name, M1, for the motor and the low voltage control relay coil, which can not be named the same. The relay coil can be named as CR.
As a non electrician this helps a lot with me understanding three phase starters. Have an old three phase drill press that I tried to use today but the start button would not depress. Looking inside the button will push down without providing power if I rotate a mechanical arm or turn down an internal amp dial. Not sure how to troubleshoot this but I do understand the principle of the switch. Thank you.
Only thing that's missing is an actual motor being hooked up. Diagrams are fine and great for understanding the circuit layout, but an actual motor, with fuse and push buttons and everything else would really hammer it home.

I recently graduated an industrial maintenance program and was looking for videos to keep knowledge fresh. Fantastic job sir!

Good explanation and one of the best I hv heard so far.
holy crap, this is the BEST video I have found, absolutely incredible, I will be watching this on repeat until it's drilled into my head. Thank you.
Really like how u explained this and done a very short recap on each part before moving on !
perfect explanation way better then any of the other videos ive seen
one could spend a month to understand what this lad explains in 15 min!
Exceptional clarity. First class.
Your concepts are clear to explain others
The best explanation I've ran across. Great job young man.
This system call DOL stater (Direct On Line) . very good explained
This is one of the best examples of a really detailed yet straight forward training videos.
Thank you
Why doesn't this channel have more subscribers/likes?
this is quality stuff here
You are the best
Amaaaaazing!
Thank you for the clear professional explanation
Can’t thankyou enough, u made how the circuit excatly works crystal clear by drawing the power circuit and the control circuit together while explaining. Good job 👍
Couldn't have been simplified any easier thank you!

Best explanation I've heard after years in the field! Thank you!
Thankyou. I am working on controls in the future. I'm glad people like you are out there.
I appreciate that clear explanation teacher
Clear Concise Excellent for beginner
GREAT VIDEO!!! Thank you for sharing your knowledge with us newer techs.
Great stuff. I took that all in first time. Very well explained. Thanks.
finally someone did explain the functionality of the circuit correctly. Excellent work!
THANK YOU!!!!
This was by far the best explanation
Excellent presentation!! Subscribed!
Good stuff, you're needed more than you know. Teach us so we can teach the youths! And so it goes.
Very clear and well explained, thanks!
Clear explanation. Please continue making these videos
im in maintenance , im a tech 2 with no schooling , your videos are nice for moving up for people , nice
Have a interview tomorrow and wanted to brush up on my electrical. It’s an E&I job and I’ve been doing strictly instruments for the last 3 years. Thank you for this video!
How’d your interview go? I got one tomorrow so this was a good video to refresh
I have an interview to work an I&E position for a plant coming up soon. Tired of being a contractor lol. Hope yall got the job
Thank you, I really enjoying the video, best explanation.
Man this is great information. Many thanks
If you can't teach someone I believe no one can! Very good!
Thank you for the thorough explanation
Excellent job on explaining on basic motor control circuit.
I enjoyed this video, well explained, this is part of my daily routine at work! Video was perfect.
Dude you so amazing you need to make more videos like that!!! 10/10!!
Basic stuff, but a very good reminder video thank you!
watched another motor control video and was confused, this cleared things up. Thanks! 👏
They way you explain is great easy to follow I'm self taught and just starting . You hit every question I may have .

Your a good teacher thank you
Thank you for this very simple explanation, much appreciated 👍
Thank you so much, great refresher
4:24 Primary side of the Transformer connected to L2 and L3 would be 277v, not 480v. Right?
480v! Line to line is 480. Line to ground is 277v
Thank you for the video, well done.
Thanks my friend,very well explained you. 👍🙏🤝🙌

Check check continuity on the switch maybe.
Very good thank you sir!
Your video is great by far the best, 👍👍🔥 however if can't do this connect again physical wiring a connector and explain as you go
this was a most awesome electro phys lesson.
well explained, thank you!
