@A_Tower @Jeremy Fielding People who know how to teach, probably. So many obvious questions he fails to answer in just the first few minutes. Why handwave hp when you can simply mention whether this is electrical or mechanical (we know it's the former, at 746 watts, but why would a novice know?)? There are four instances of this kind of thing in the first three minutes. Such a shame. A good teacher always takes the opportunity to tell you more, not less.

I was just telling my wife how much I enjoy and learn from your channel. You are very intelligent and able to bring things down to my level . I am also impressed how you can build things and fixtures to hold the testing equipment. Your children are lucky to have you to teach them. Cheers Jeremy !
Thanks for the information. You explain things very well. Welcome back. I never fail to learn something from your videos. You manage to demystify complicated subjects.
Perfect information for me. I called the manufacturer looking for what the overload relay needed to be set to. You just helped me to understand that it's printed right on my label. Nice video!!! Thanks!!
Love your videos. I have always played around with motors and electronics and seeing a video titled for beginners I am hesitant to click but so far you always teach me something new. I firmly believe the best way to learn anything is having a very good understanding of the basics and you are very good at providing all that.
Brilliant Jeremy, the amount of good motors I have seen throw away because people are baffled by them and maybe don't have your creative ideas, you explain things very well,thanks mate
You've missed your calling my friend..you would make a great teacher your very thorough, humble, and you keep the audience watching and listening... restoring 70+ft yacht for a research vessel...I weld fab and mechanics but very nervous when in comes to electrical I have 6 large electric motors that need replacing and after watching your video I've decided to do it myself instead of paying a electrician thank you and I'm sure I'll be watching many more of your videos...
Thanks to you I have two blender motors, 6 printers of different ages and sizes, and am driving home with my second treadmill from this years “spring cleanup”. I spent several hours in the wee hours of the morning Driving through alleyways in some parts of the city where people put theirs spring clean up trash, and up and down every other street in that city. Just bought a lathe and a mill that should be here Friday. So far my wife’s been a good sport. But she hasn’t seen inside the shed yet😂
I learn so much from you. And I know exactly how it feels when you show people the 'inventions' you've done. Even if they don't really appreciate it, that moment you show it to them and it works like how it should be. Priceless! Thank you Teacher Jeremy. You are a natural teacher. Very patient and it feels like you won't scold me if I accidentally make a mistake somewhere in my project. Thanks again!
Awesome job with the describing the label. I knew about half and always wondered about the rest. Also, love the projects you do from salvaged motors! Thanks much.
Just the info I needed as I am looking to buy a second hand motor - now I have a little more knowledge on what the labels actually tell you. Much appreciated !
excellent video. I knew most of this but not the service factor or insulation class. Using an asynchronous induction motor as a wind generator, I have burned up the insulation so I need to find a beefier motor.
I know this video is like two years old, but just wanted to say your videos are great! I don't think I've ever made a UA-cam comment before, to tell you the truth. As someone who loves to tinker, has no formal engineering training, and gets in over his head all the time, i absolutely love your videos. All the things I've always wanted to know about motors and other things you post, but never had the time to look up or got wildly confused when I did. So, just wanted to say thanks for making the content that you do!
Jeremy, Treadmill Duty: this rating means moderate use for the first month after purchase, followed by a sharp decline in use and a sealed housing to protect the motor from dust once it's moved into the garage to be stored for 20 years.
I have always been interested in the science behind machines, mechanics or making things in general. Yet never had the knowledge behind much of it. Jibber jabber jibberish if i was to have someone teach me lol! So I really appreciate the serious time you take in explaining EVERYTHING in your videos! It’s given me so much to the point I am finding ways to do the projects i’ve always dreamed of doing! Thank you Brotha
Mr. Fielding, I always enjoy your videos and find them most helpful. I always hit the like button as soon as I click on to your videos as I know I will like them and will learn. Thanks for taking the time.
Jeremy, listening to you is like a zen meditation... you are humble and have a tone that is so approachable... I think of WWJD (What would Jeremy Do) when I face my class. BTW... I had a 5 hp motor that was running a Hydraulic pump fine in Pittsburgh but when they moved the equipment to Connecticut it would not cut it... the voltage dropped from 230 to 208 and the current went up and would blow the fuses. Needed to change the motor for the new location. The challenges of running near the edge.
These are the best explanations I have ever heard on electric motors. You've earned yourself a new subscriber. Please keep up the great work. I have been collecting 18650 batteries and plan on building myself an electric bike, or go-cart eventually, I will definitely be coming back to learn more.
Very nice to see that you convey something good with your knowledge of the industry and the interested parties. We like the power of the big electric motors.
This is an excellent video. I can't thank you enough for the label deciphering! I know I could probably find it dryly presented in some book, but your explanations are so easy to listen to and understand. Of course, I'm going to go through the video and write this all down but, without you having explained all of the notations, my cheat sheet would be worthless to me within days.
I recently took my old treadmill to the dump, also a washer and air conditioner. I wish I would've watched your videos sooner. I would have 3 motors to experiment with. Great videos. Very informative.
Very good information. I've looked at these labels many times, but I didn't know what they were trying to tell me. I'd be interested in learning more about adapting motors to pulley systems like you have in your bandsaws. How to adapt a motor to a certain device speed, yet staying within the performance specs of the motor.
I started a very ambicious Project of connecting a hole farm to a Arduino.. but i dont even know how to change a light bolt 🤣 your vidéos are helping me a lot!! Tanks 🙌🏽💎
I just happened to come across one of your videos a couple hours ago and I've been watching different ones from you since. This video caught my attention because I've been having trouble with my 5 horsepower Ingersoll air compressor motor, and trying to make sense of everything on the plate of the motor was confusing. I like how you talk about using treadmill Motors a lot, last year I made a electric wire stripper using the motor and rolllers off a treadmill. And it works awesome LOL
You are one cool cat my friend! I love your videos, and learn a lot from them! Keep em coming! Would like to see what you can make using a garage door opener motor.
Much appreciated JF, you've given me hope on trying to grasp the world of electronics, I'm starting to believe i can build my own stuff too ✌ 👍 keep it up man thanks
Great man thanks for the time you are sharing. Years of experience explained to the point that you just saving years off the learning curve for me. 😂😂 I only watched 4 videos. 👍 👏
Omg I think I just found my favorite channel ever!! I’m serious!! I’ve been taking parts from things for a while now.. but then I was like.. uh what now? Thank the gods for you 😃😆 for real though thank you.
You videos are some of the best on UA-cam your a very smart guy I learn a lot from your videos thanks for your time I’m not sure if you have any up I just found you not long ago but if you don t could you do couple videos on how to use a multimeter and how to test th8ngs with them
Great Video! I'd add when they talk about the motor insulation rating; they're talking about the electrical insulation of the windings if I am not mistaken rather than any kind of temperature insulation as we have in our homes and around steam piping..
Just incase u still wanted to know, Treadmill motor energy is measured in horsepower (HP) and can be sorted into three different rating systems: 1. Peak Duty: Generally the weakest. “Peak” stands for the peak horsepower that the treadmill will reach and no more.
Treadmill is a device formerly used for driving machinery, consisting of a large wheel with step fitter into its inner surface, it was turned by the weight of people or animal treading the step and now with small motor you show on this video.
FYI, I've used your video's, not exclusively, but predominately, to learn what I currently know about motors. The text that I use in school is decent but you present demonstrations and really clear and concise information that is not only pertinent to someone learning about motors but actually fun to watch casually as well! Community colleges suck! I wish there was an accredited online based platform where the students had power to choose their instructors based on their proficiency and ability to teach. I learn more from youtube video's like yours in a short span verse the hours every day I have to sit through these traditional classes. Professor thanks for the tutelage and I'm looking forward to more of your video's! Oh and question, do you know of some applications where a three phase motor utilizes the neutral from the common of the three windings? The wye configuration is typical but I wired a motor trainer at my school in the wye configuration with the common to neutral on the trainer and it smoothed out the motor sound and dropped the amperage draw. I explored on some on various electrical engineering channels and found out, according to the channel host, that train motors utilize this wiring configuration. When I wired it that way my instructor freaked out and told me that I couldn't do that and I might burn the motor up. He proceeded to then demonstrate how to wire this motor in the delta configuration. Which promptly burned up the motor within about 1 minute of operation... Yea that trainer had been at the school house for like 40 years so sad.. I read that the delta configuration in a transformer has the affect of a so called wild leg that has a much higher voltage output on one of the three windings. Though I'm just learning about all this, perhaps this is what caused the motor to burn up?
I had AC problem at home a couple days ago, called the ac tech, he replaced the blower motor. I kept the " bad" motor he replaced and run it in the kitchen, and it's running! What should I do, appearantly the guy didn't think I could wire it and run it, because I have different accent( Turkish) so I must be stupid. Should I go to court or something?
So glad to see you again! My collection of motors is starting to grow... but I honestly don't want to just "collect" them... I want to use them. The problem is they are all AC motors... and the next project I'm going to try requires a DC motor. Question... how do you get these motors? Where should I be looking? And should I be looking for whole appliances/devices, or specifically the motors out of said appliances/devices?
I found a really odd motor in an old shack that turned out to be a repulsion start induction ran motor. Instead of a starting capacitor and aux winding, it used a set of 4 brushes to start and a centrifugal switch disengaged them once up to speed. You set the direction of the motor with a knob on it that adjusts the alignment of the brushes
Excellent video! 👍👏👏 Just my luck, my Motor doesn't list the frame. As an idea, I haven't found many instructional videos on troubleshooting/diagnosing any potential issues. An example would be to test the separate windings, or capacitor (s). Thanks again for a great informative video.
Some one recommended it... a lot of people listen to my videos without watching them. And several have complained that I put notes on the screen but they don't know I corrected something. Then someone said "hey could you play a sound when you add a correction" I loved it.
@@Jeremy_Fielding Ha ya, I was the one who suggested that, I was just being cheeky. I like the sound you picked, I think that's a good choice to start with. Did you record the sound yourself?
DUDE! Thank you again for the suggestion. I love it. You see I played it even though I didn't get to use it to correct anything... I downloaded it from a sound library. This one is really close to that soothing smooth chime I am looking for. I am going to change it a little before the next video.
The Nema design B letter designator describes an entire torque curve shape of that AC induction motor, including the fact that it will have breakdown torque or not. With design A or B motors the breakdown torque can be used to get more power and torque out of the motor by overloading the motor. It's actually used in some very specific applications like in hydraulics and shredders where RMS mechanical power matters more than continuous rating of the motor. In such applications as those two, it is the average heating of the overloaded motor with rest periods in between that is equivalent heating to the motor being ran at its full rating continuously. So if I took such a motor and had it submerged in mineral oil and had the oil temperature checked by a thermometer, and motor A was being loaded to produce 2 horsepower continuously while motor B with sufficient breakdown torque (you only use a percentage of the max breakdown torque; never the full amount or you risk stalling motor) was being overloaded for a short time and then allowed cool down periods, then the average heating of the oil will be the same for both. We call this mechanical Root Mean Square power, and it is the exact same formula as it's electrical equivalent when defining AC voltage equivalence to DC voltage using a resistor to get the same heating equivalence in a liquid.
Who downvoted this guy? He’s great. Calm and clear, gifted teaching skills. I’d consider myself very fortunate to have this guy mentor me.
I would too, the reason I'm here is to learn how to understand the motor label.
Agreed!
@A_Tower @Jeremy Fielding People who know how to teach, probably. So many obvious questions he fails to answer in just the first few minutes.

No matter what, every channel has haters, some people do it for no other reason than just because.

Another great video Jeremy. I am recommending that our local tech club hobbyists watch it, and we play it to our local tech kids.
Great info. I like how you explain without talking down. Very informative!
Thanks for the information. You explain things very well. Welcome back. I never fail to learn something from your videos. You manage to demystify complicated subjects.

I can't tell you how much I appreciate your videos. Truth about my man!
Dude, I cannot believe how helpful this guy is. Much appreciation.

Again a video of yours where it ended and I wondered where those 18 minutes had gone! Not many youtubers manage to do that.
If not for his other vids and playlists id have been like wtf I need more info lol
I learn so much from you. And I know exactly how it feels when you show people the 'inventions' you've done. Even if they don't really appreciate it, that moment you show it to them and it works like how it should be. Priceless! Thank you Teacher Jeremy. You are a natural teacher.

great video Jermey, love your style, knowledge and you speech style. one of the best channels i know of
You are clear, patient, and a good teacher. I’m taking industrial maintenance and I’m learning from you and my teacher on 3phase motors
Jeremy your videos are fantastic and packed with useful information. Thanks much for your time and knowledge. 👍
Top Shelf all the way. I really am getting a lot out of these videos. Old retired guy here with thousands of projects to do and ready to get started.
Super helpful information here. This subject has always intimidated me. Thanks!
Same here.
Your a great teacher. Love your videos. You have encouraged me to tear apart my washing machine.
Great teaching style, practical and to the point. Omitting excess unnecessary verbiage, much appreciated!
This is my 2nd video, thanks for keeping the explanation straight forward and simple.
It's great that he keeps mistakes in and corrects them on-screen. Major learning opportunity and a sign of humility.
Awesome job with the describing the label. I knew about half and always wondered about the rest. Also, love the projects you do from salvaged motors! Thanks much.
Just the info I needed as I am looking to buy a second hand motor - now I have a little more knowledge on what the labels actually tell you. Much appreciated !

I agree he's a great teacher
Thanks for the video.
Talk about helpful. I will go back to this video many times probably. Thanks again. God bless all
Very pleased I found your channel...powerful information and conveyance is easy to understand
Great Video Jeremy!!! thanks
I agree with the person called a tower...the guy is very good
You videos are some of the best on UA-cam your a very smart guy I learn a lot from your videos thanks for your time I’m not sure if you have any up I just found you not long ago but if you don t could you do couple videos on how to use a multimeter and how to test th8ngs with them
So happy to see another of your works. Good information explaining some things I wondered about. Thank you!

thankj you for the great video again! i will recommend this to our interns the next time motors come up.
Damn, stumbled upon this before video 3 is out.
Alright, alright, you sneaky bastard. You win. You just got yourself another subscriber. ;)
Another great video!
Great video. I am looking at using a variable frequency drive with a 3-phase motor running 1-phase input. Pretty cool, but still learning.
So glad to see you again!
My collection of motors is starting to grow... but I honestly don't want to just "collect" them... I want to use them. The problem is they are all AC motors... and the next project I'm going to try requires a DC motor.
Question... how do you get these motors? Where should I be looking? And should I be looking for whole appliances/devices, or specifically the motors out of said appliances/devices?
I talk about where the motors come from in part one of this series
I liked as soon as I saw the episode number
Very informative video thanks thanks bud.🍺
Another great instructional video. Helps when salvaging motors. Thanks for sharing! : )
Very interesting AND usefull. Thanks 🙏
I found a really odd motor in an old shack that turned out to be a repulsion start induction ran motor. Instead of a starting capacitor and aux winding, it used a set of 4 brushes to start and a centrifugal switch disengaged them once up to speed. You set the direction of the motor with a knob on it that adjusts the alignment of the brushes
Hello, your explanation is very clear and informative, thank you for that!!
Good comments…enjoyed
Great video my friend. Very informative.
Excellent video! 👍👏👏 Just my luck, my Motor doesn't list the frame. As an idea, I haven't found many instructional videos on troubleshooting/diagnosing any potential issues. An example would be to test the separate windings, or capacitor (s). Thanks again for a great informative video.
Lots of great information Jeremy. Thanks!
I like the sound when you put a note up :)

We call this mechanical Root Mean Square power, and it is the exact same formula as it's electrical equivalent when defining AC voltage equivalence to DC voltage using a resistor to get the same heating equivalence in a liquid.
