Motor Contactors Explained

This video is about the basic principle of operation for motor contactors. I talk about the theory of operation, and take apart a very common contactor to look at the inner workings. Also, some common failure modes are discussed about contactors. Please comment below with any questions. like and subscribe if you see value in this content.
Thanks for watching!

After 50 years as an electronic and electrical engineer, I am looking for a change of employment leading up to my eventual retirement.
I thought that I would embark on a "refresher" course prior to interview just to be sure I was up to date and "savvy".
I love your presentation. You keep it clean and simple, totally informative and do not ramble. You are easy to follow and at no time do you bore me to sleep.
I honestly wish I'd had instructors like you in the Royal Navy all those years ago.
Keep up the great work and thank you.

Incredible video!!! Extremely informative! Thanks for simplifying the information.

[@kevinsluder3711]

Please make more videos! Some of us really need them to develop new skills.

Sir you are highly respected for this great display,, YOU ARE AWSOME. I really wish we can get videos on digital control systems wiring on panel boards🙏🙏🙏

[@mgove4052]

You have explained to me what no one could explain in over 10 years working in the electrical field. I did not bother about high voltage installations because of that. I only did residential work. Thanks you so much.

[@markgil9249]

I've trouble shooted these..replaced them but never really got this deep with all the possible failures. I've always had them fail open. Thank you for the in depth detail.

[@nkuluhuru]

Very informative 🙌

[@summerseve502]

Make more videos please, you are gifted with explanation

[@toroitichpatrickyegon4866]

Beautiful. Working on such videos as well to transform our electrical content. Thumbs up sir.

[@koarivera9151]

Awesome video you earned my subscription this will help me tremendously as I'm working in a giant industrial facility right now

[@kennethlobo4420]

Great video.Thank u so much.would be going thru it again. Videos like these help in the field.

[@adrianfrancis1156]

Great videos keep up the great work. Videos like these will help future generations. In the Industrial Electrical Field.

Thanks, Adrian! I will do my best to stay motivated!

[@eliasd.6826]

Easy explanation! Thanks 🤗

[@ordermurah5491]

Good explanation and good quality video. i hope you keep update di video because all of you explanation is easy to understand

[@simpliciocamirino2271]

Thank you for that sharing sir.

[@basilgreen5070]

Definitely enhancing my understanding for school

[@fayiznalu8411]

Thank you for sharing 🙏

Wish this was available as a apprentice 30 yrs ago ... this will make better more knowledgeable Electricians ..#godblessnorthamerica

[@zacharymorrison1370]

Very good explanation and teaching bud!

[@electriccreative511]

great video

[@MB_583]

Very good job 👍, thanks

[@celmusamusa1416]

Wow!!! 👏🏻👏🏻👏🏻🙏🏼 thank you so much bro, we have learned a lot from this video...🤞🏽

[@manny7568]

Thank you bro you helped alot

[@tesfahungetahunargachew4328]

Nice teaching tnx bro

[@crbeltran1972]

I like the way you explain the basics. Ever think about writing a book with easy to understand images?

[@Jason_Canada]

Awesome from huntsville ontario canada

[@louistate8927]

Good explnation

[@pjcloete7414]

HI, thanks for sharing these videos. Do you have any plans on creating additional videos such as this one, for the other components in controls systems, such as relays, overloads, timers etc?
I think you have done an excellent job with this video.

[@goldhealer]

Thank you for sharing, a really thorough explanation. Now I understand the basic concept.
Is it possible to use DC (apart from AC) for the coil to close the circuits?

[@themaintenancefactory2592]

Yes, in fact that is a very common practice.

[@jeffreyhueseman7061]

Make sure the spring is inserted correctly, or the armature will not make contact for the motor. The core can be rotated 180 degrees to clear other equipment and still work.

[@MiltonRamirez-fl1eo]

Can someone give me advice why I don’t get volts on the left side of the auxiliary coil motor starter, I only get 120 volts on the right side of the auxiliary . And therefore my coil would not close to send power to my T1, T2, T3. The left side is wired to back 3 terminal and to my SOL common from the circuit board. And my right coil terminal is connected to the hot power ( on/off) switch and it goes to L1 to the circuit board?
