This is the best video I have ever seen with a thorough explanation of the circuit especially if you are a self learner as I am. Eleven minutes of this video equals to weeks of learning in schoool. Good job sir, keep those videos on rolling out!!!
I'm in school for this now and my instructors are barely explaining these simple concepts. Your explanations pretty much gave me more confidence in understanding this stuff. Subscribed!
Hey Walter. I have been “ one of those electricians “ for a long time. The MC aspect has kind of stopped me in my tracks quite often. I work for a zoo and so my duties as an electrician can vary greatly. Thank you for this and “ sparking” my interest with bettering myself. Good things!
Thanks so much for this video, and the entire series!! Just a hobbiest, but am installing CNC mill and manual lathe in home shop. Came to these videos based on VFD intro videos, stayed to watch these basic tutorials on motor control. Last year I had 2 electricians helping me to troubleshoot a 20 yo but "brand new, unused" 18" bandsaw. Couldn't get it to start even though all the switches seemed fine. I finally discovered that by manually closing the contractor, the motor would start, thus eliminating the motor as "the problem." I used a volt/ohm meter to verify that power was making it to the motor control inputs, and that the basic control switches were working as intended. I went so far as purchasing a replacement control unit from Amazon but then I was stuck. The second electrician was brought in at this point. He was able to diagnose the problem with the original motor control unit (from ~1988)--the primary relay coil had break somewhere so it would not energize. The contractor units have been standardized for decades, so the second electrician (the 'motor-control whisperer') as able to harvest the coil unit from the Amazon replacement and use it in place of the original unit. Everything just snapped together and now the unit operates properly with it's original control switches and front panel intact. While this was a great result I don't like to think about how much all that cost (lets just say a few hundred dollars). Having watched these intro videos on Motor Control and 3-wire start/stop circuit basics, I could now understand better how it was all working (or not working). Don't know that I would have figured out what the problem was, but at least I would have had a chance. Finally, I'm going to keep watching this series because, for example, I may want to add an additional stop switch to the bandsaw. The red momentary NC switch assemblies are readily available on Amazon. From these videos, I think I understand how to add more to make the machine safer to use with a more accessible STOP switch.
This is all new to me and I have seen many videos and try to understand how these connectors work and, until today , I was still in the dark until I saw this different way of explaining circuits. This has to be the best explanation I have seen. Thank you.
Excellent video. Thank you. Troubleshooting 3 phase 480v. I love it. Just today, had one phase open, after following conduit, found a bent 3\4 piece of EMT and a burn spot. Friday the guys changed a screen on the El Jay shaker, evidently when they dropped the screen over the side onto the ground they hit the conduit for the feed conveyor. So, overload tripped out from single phasing. Used a tubing cutter, on EMT and added a box a new seal tight. Reset overload and it's up and running again. Boys were clueless they even hit it.
I am a me engineer. I started to watch your videos today and amused by quality and simplicity of the information that u share. Thank u very much for the hard work. U would be an amazing teacher.
Great job! First and only video I have seen where the narrator explains the seal in contact correctly, ie it is an auxiliary contact and not just some random normally open contact somewhere.
This is a great refresher video for plant engineers like myself, who work on many different building concerns, including building wiring, motor controls, and logic drive systems. Thanks.
I just started a job where I need to learn this stuff and I love my job. They are training me, but this video was as so much more helpful. Thanks can’t wait to see more.
Great explanation on how to actually understand how the circuit works, I work in a huge paper mill when I'm in the MCC room looking at this bucket my motor could be hundreds of feet away where the wires leaving the load side of the motor starter goes to a local disconnect first , then feed the motor for protection.
I really enjoyed your video, it gave me a clear understanding of motor control circuit, but not only that, it gave me a clear understanding of how to correlate plc and line logic
I have been self study PLC ladder programming & wiring a pump, this video explain everything so clearly, TQ hope to see more video with actual electrical circuit and its coresponding ladder programs
Very good layman’s terms , easy to follow. Only thing better would have been showing how you hook it up to the starter coil on an actual starter. Up close. That would have made it PERFECT!!
Thanks for the wonderful video! A presentation explaining how a relative novice can best cobble together misc budget/auction items together to form a versatile workstation would be monumental.
One of the best tutorials I've seen enjoying your training methods. Detailed explanations easier for me to understand than some of the field training I get.
Thanks, these Videos helped tremendously, I’ve worked on variety of Control Panels for Conveyor systems, And in my case had issues with actual loose contact wires that caused initial replacement of several components because, couldn’t determine actual cause of tripped breakers, also pitting and much carbon buildup that causes resistance buildup or arcing, loud explosive sound and smoking out of the Panels, at first thought was overloads because the high Current demands but turn out to be gap between contactors
I think once you see someone wire up the whole circuit, then do it yourself, you can really get a sense of how simple it is. I think VFD's are a lot easier to hook up and you get a ton more control. Centrifugal switches are another example of a simple latching switch that uses momentary buttons for start/stop like on a table saw.
Infact you did well sir, you are the greater master, am enjoying your lecture. I know this already but am still looking forward to know more sir thanks 🙏
thanks, great video. I'm just dipping my toes into this as I have an issue with a machine in the workshop and needs to be rewired so thank you. I think the hardest part is finding currently is what comments would work in my situations, I have a DOLD soft start and DC brake unit that I am trying to understand the wiring diagram of but some bits don't make sense, also do I put other breakers before it. thanks James
I really appreciated and liked this video cause it gave me the basic instruction of how 3 wire start stop. I'd like to see more videos like the one multiple start and stop buttons.
I really like this video, I want to see with a selector switch on-off-auto, two pilot light green and red, with the overload. You can explain it in the computer but also I wanna see how you wire all that.
Great demo, thanks. Thought you were going back to the display. I got it although it would be cool to see the display wired along side the ladder diagram to get a hands on visual perspective of the ladder to actual field wiring. Yes, I am an electrician, lol.
Great explanation. Also, a lot of times the control voltage is tapped off of one leg of the load side of the contactor. So you don't have the need for a seperate control transformer. The power from the line side of the contactor goes straight to one side of the stop button. I agree about some electricians being intimidated by a motor controller. But it really is simple if you stop and look at it on paper.
Usually you dont use 277v pushbuttons. Youre more likely to see a separate 120v or 24v external power source than 277v push buttons, assuming youre using 480V/3-phase motors.
You’re an excellent teacher. Your thought pattern combined with great visuals really reach the audience especially those who learn differently. Thanks for the efforts.
Till 2024 I watched a lot this kind of videos, this is the best video I have ever seen with completely step by step animation. I don't have to use too much imagination force to understand all. Great job. I wonder is there any contactor that uses its Lines to activate the control circuit, rather than use external 120V power source ? If yes, how is the circuit look like ?
I enjoy your videos, I learn, electricity is not my subject but It comes to a point where you have to evaluate the risk and to save money to diy. PLEASE DO A VIDEO ON Drum switches, like to wire a splt phase 3 speed motor
i worked on these systems with U P S conveyor systems all buckets are alike in miami main hub there are if i remember there where 900 buckets one per conveyor ,,,,,,good job ,,,,,explaining this , your right most electricians dont like doing this ? ,,,,
This was very good. This did make it simple. The diagrams and physical equipment was complementary and helped. If the words were a bit bigger on the diagrams it might help some though.
You are really perfect, I like to make a video on Soft Start how it works what signals it has the wiring connection and the interface between it and control system and what kind of signals sends as feedback, and one for VFD as well, really appreciate it.
This is the best video I have ever seen with a thorough explanation of the circuit especially if you are a self learner as I am. Eleven minutes of this video equals to weeks of learning in schoool. Good job sir, keep those videos on rolling out!!!
Hi
Yes an excellent video simple to understand!
I like it
I'm in school for this now and my instructors are barely explaining these simple concepts. Your explanations pretty much gave me more confidence in understanding this stuff. Subscribed!
6 weeks of motor controls class summed up in 11 minutes. Great, simple, effective content.
"Latch circuit" That term helped me remember that using a N.O. Aux. contact keeps the circuit energized after pushed. Great explanation video !!
Hey Walter. I have been “ one of those electricians “ for a long time. The MC aspect has kind of stopped me in my tracks quite often. I work for a zoo and so my duties as an electrician can vary greatly. Thank you for this and “ sparking” my interest with bettering myself. Good things!

Thanks for the awesome comment! I appreciate it and I am glad the video helped you!
I've been doing electrical for 25 years and just now start doing motor controls and this really helped me out a lot thank you
Absolutely the best and clearest description of a motor starter that I've seen. Thanks

Good job troubleshooting the motor today!
Great video. In water/wastewater industry. This type of online training is priceless. Thanks for the service!!
Explanations clear, well demonstrated .
Thanks for such an awesome video
I watched quite a few contactor videos and this is the only one that clerifies how contactors work.
I am a me engineer. I started to watch your videos today and amused by quality and simplicity of the information that u share. Thank u very much for the hard work. U would be an amazing teacher.

Thank you very much!
This is the best illustration for a basic motor starter. Thanks!
I just started a job where I need to learn this stuff and I love my job. They are training me, but this video was as so much more helpful. Thanks can’t wait to see more.
This is the best demonstration on motor controls I have seen.
Damn, where was this video when I took motor control. Excellent job.
Where did you take Motor Control? any links?
@@shahshakib5234 when I was an apprentice at the IBEW.
i am not an electrician but i clearly understood the basic 3 wire electric motor system advantages . . .perfect presentation ,
Great explanation on how to actually understand how the circuit works, I work in a huge paper mill when I'm in the MCC room looking at this bucket my motor could be hundreds of feet away where the wires leaving the load side of the motor starter goes to a local disconnect first , then feed the motor for protection.

I’ll like to see how you wire something like that with wires and all of that! Thank you
I love this guy!
What a cool demeanor he has and he's very informative.
Clear, thorough explanation of basic start-stop MC circuit. Thank you
I immediately shared this video with my classmates. It's a miracle of instruction. Thank you!
Thank you for sharing the video and taking the time to comment.
Great job, you simplified it without over talking it... brilliant
Great video very simple to understand best explanation I have seen
Very good layman’s terms , easy to follow. Only thing better would have been showing how you hook it up to the starter coil on an actual starter. Up close. That would have made it PERFECT!!
I wish all journeyman, foreman, instructors,... were like this guy.
GOD BLESS THIS MAN!
Thanks for the great comments!
I agree

Walter, thank you for creating these videos with explanations anyone can understand (even me!).
You’re welcome! Glad they are helpful
Currently preparing to take my license for engineering and this help so much. Thank you!
Glad you found the video useful!
This is awesome. I just start watching your videos & I love it. I am sure this will help me in my career as electrical officer in merchant Navy.
the visual of the hardwired to diagram really helped, thanks.
Man! I like your energy level, how well you communicate,...
I seriously am intimidated by controls.

hello Linh, the software I used for this demo is called Constructor. here is a link to the info page. www.cmhsoftware.com/constructor.html
sir, i work in power industry and this is one of the best videos out there, liked and subbed
I really appreciate the way you explain the circuit. Thanks
Thanks for the video. You use terms as if everyone knows exactly what you’re talking about. It is a great effort
Nicely said , Great Instructor , I would like to see more of your videos about motor controls. Thank You for the information , You Rock!
Infact you did well sir, you are the greater master, am enjoying your lecture. I know this already but am still looking forward to know more sir thanks 🙏

Excellent Video on three wire motor control systems. Very easy to understand with ladder diagram. Thanks
Great demo, thanks. Thought you were going back to the display. I got it although it would be cool to see the display wired along side the ladder diagram to get a hands on visual perspective of the ladder to actual field wiring. Yes, I am an electrician, lol.
Phenomenal video. Just need field wiring example.
Yes pleassssse, field wiring example
Very good video to keep my rusty mind going.
Thanks very much

Hey man, great video on motor control. Very good relation to anyone that has worked with relays or contacts in the field.
You’re an excellent teacher. Your thought pattern combined with great visuals really reach the audience especially those who learn differently. Thanks for the efforts.
craig seib thank you for the nice comment. I really appreciate it.
Excellent thanks for the clarification easy to understand what you're teaching other videos and I've watched a lot aren't as good as yours
In one 1 min. I'm impressed 💥
Till 2024 I watched a lot this kind of videos, this is the best video I have ever seen with completely step by step animation. I don't have to use too much imagination force to understand all.

The simplicity you explain make easy to understand. Thanks for such a great 👍 video
i worked on these systems with U P S conveyor systems all buckets are alike in miami main hub there are if i remember there where 900 buckets one per conveyor ,,,,,,good job ,,,,,explaining this , your right most electricians dont like doing this ? ,,,,
This you making this video it is so simply clear. Geniuses make complex things look simple and understandable
Great video clearest explanation I’ve heard and seen thanks
Thank you for actually demonstrating
Thanks for sharing your knowledge very informative, it
inspired me to focus more making electrical video
You are great teacher!!! Thank you so much and keep up the good work.
Here is the software I am using
www.cmhsoftware.com/constructor.html
What software do you use for your schematics? You've made this 10x easier to understand.
It’s called Constructor
This was very good. This did make it simple. The diagrams and physical equipment was complementary and helped. If the words were a bit bigger on the diagrams it might help some though.
Thank you for your very thorough explanation.
You are welcome!
Thanks Chazz. I loved A Bronx Tale.
Great video, thank you! I just wish there would have been a bit more blue in the introduction.
Youre a very, very good teacher
Thank you,
Thanks, for taking time out to help us. Videos are great.
Thanks it helped me alot. Can you show more videos. I just started as an apprentice. And I need all the help I can get. Thanks again.
Thank you for producing this video and for dropping knowledge bombs 💣 😎👍🏼

Nice well explained simple, i just started a job where i have to troubleshoot industrial machine very helpful to me thank you very much
Many thanks Walter fabulous teacher 🇬🇧🇬🇧
Thank you sir, for another excellent learning video
Great !!!
Just starting with motor controls !!!
the best Motor Control video yet, I hope you keep making videos like this one but alot mote complicated.
Great demonstration
Excellent video. Best I have ever seen. Now I know. Thank you
Gail Bartholomew thanks for the comments
Thanks Walter, you made it seems so simple
Thank you for sharing this great video.
This was a great video, thank you!!
You are really perfect, I like to make a video on Soft Start how it works what signals it has the wiring connection and the interface between it and control system and what kind of signals sends as feedback, and one for VFD as well, really appreciate it.
مصطفى الربيعي I have several video’s on VFD programming and wiring. I will need to make a soft start video soon
Thank u! You would be amazed, trade school teachers cannot simplify it like this, it's almost as if they dont know how it works!
The best of the best!!! Thank you señor!
One of the best videos. Thank you
Need more of these please.
This video was very helpful. Thank you.
thanks for these videos God bless you.
Thanks sir such a nice and very easy way to describe power and control circuit of electric motors.
Excellent learning. Keep sharing your knowledge..👍
that was brilliant , thank you .
I love your tutorial. Thank you.
Great video, loved your visual explanations,really effective, keep it up
this is a great video, thank you. I would like to see how this is applied directly on a machine
Never been around production lines? Miguel Ramos
Excellent explanation.
