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!!!

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 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.

I wish all journeyman, foreman, instructors,... were like this guy. GOD BLESS THIS MAN!

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

Damn, where was this video when I took motor control. Excellent job.

Thanks, for taking time out to help us. Videos are great.

These videos are brilliant thank you. Helped me a lot. Craig U.K

Thank you for producing this video and for dropping knowledge bombs 💣 😎👍🏼

Hey man, great video on motor control. Very good relation to anyone that has worked with relays or contacts in the field.

Quality video well delivered - and kept simple 👍👍👍

the visual of the hardwired to diagram really helped, thanks.

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

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.

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.

Absolutely the best and clearest description of a motor starter that I've seen. Thanks

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.

Thanks for sharing your knowledge very informative, it inspired me to focus more making electrical video

Thanks Walter, you made it seems so simple

Clear, thorough explanation of basic start-stop MC circuit. Thank you

Very good video to keep my rusty mind going. Thanks very much

Thanks Chazz. I loved A Bronx Tale.

We would love to see more like this one:

I love this guy! What a cool demeanor he has and he's very informative.

Thanks sir such a nice and very easy way to describe power and control circuit of electric motors.

Nicely said , Great Instructor , I would like to see more of your videos about motor controls. Thank You for the information , You Rock!

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.

Hell yeah, I will subscribe, this is very interesting. Thank you very much for sharing this SIR, I really appreciate. 👍

I'm happy to hear you Thanks lot

I watched quite a few contactor videos and this is the only one that clerifies how contactors work.

I really appreciate the way you explain the circuit. Thanks

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.

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.

Great job, you simplified it without over talking it... brilliant

clear presentation,,thank you

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.

The simplicity you explain make easy to understand. Thanks for such a great 👍 video

Great video. In water/wastewater industry. This type of online training is priceless. Thanks for the service!!

This is the best illustration for a basic motor starter. Thanks!

One of the best videos Ive seen on the explanation of this, especially for a refresher when you haven't been around it in a bit, thank you!

Phenomenal video. Just need field wiring example.

The best of the best!!! Thank you señor!

Need more of these please.

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

Wow!! An amazing video! Thank you

This you making this video it is so simply clear. Geniuses make complex things look simple and understandable

Awesome instruction keep the videos coming.

i am not an electrician but i clearly understood the basic 3 wire electric motor system advantages . . .perfect presentation ,

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

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!

thanks for these videos God bless you.

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.

thnk you sir, it was a great video and i learned a lot from it.

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.

Excellent learning. Keep sharing your knowledge..👍

Thank you for actually demonstrating

I immediately shared this video with my classmates. It's a miracle of instruction. Thank you!

You are great teacher!!! Thank you so much and keep up the good work.

Very nice video...explained very well...

Walter, thank you for creating these videos with explanations anyone can understand (even me!).

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.

Thanks for the video. You use terms as if everyone knows exactly what you’re talking about. It is a great effort

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

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 🙏

Awesome video.I want to learn more about wiring starters and different coil voltage. I’m an electrician and would like to know in depth about motor starters.

Wow thank god for you cause I can wire 3 way and 4 way switching devices with out thinking about q

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.

Thank you sir, for another excellent learning video

Great video clearest explanation I’ve heard and seen thanks

This is the best demonstration on motor controls I have seen.

Excellent Video on three wire motor control systems. Very easy to understand with ladder diagram. Thanks

Awesome. 👏🏽 Thank You

Awesome video. Thank you

Thank you. And yes

that was brilliant , thank you .

Very good video, thank you.

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.

fantastic video, I got a better understanding of motor control from your video ..than the electrical course I am doing at the moment. thanks for sharing

Currently preparing to take my license for engineering and this help so much. Thank you!

Wow great video very informative. Thanks man!

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.

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.

Keep them coming.

Thank you very much.

Great !!! Just starting with motor controls !!!

Excellent explanation.

Thank you for the knowledge sir

Many thanks Walter fabulous teacher 🇬🇧🇬🇧

Man! I like your energy level, how well you communicate,... I seriously am intimidated by controls.

awesome! keep going

Thank you for this video

Excellent video. Best I have ever seen. Now I know. Thank you

sir, i work in power industry and this is one of the best videos out there, liked and subbed

I love your tutorial. Thank you.

Great video, loved your visual explanations,really effective, keep it up

Great video!!!

In one 1 min. I'm impressed 💥
