Any additional notes will be added here.
1. The biggest difference between using the HF speed controller and the DC speed controller (other than reliability) is the speed controller dynamically adjust the speed as the load increases. If you just use the HF speed controller the motor will slow down under load. The KB speed controller is "smart" and will adjust the the power output to maintain the speed.
2. The Auto transformer is also often called a "VARIAC" and I bought mine on ebay for $90 new. Model number TDGC2-2MK. It can handle up to 20 amps which should be plenty for most people.
Final Note:
PLEASE UNDERSTAND...I receive hundreds of messages on all platforms (email, Facebook, Instagram, comments, etc) asking for advice, and help with projects. At this volume, I simply can't do one on one advice. I have tried to help enough times to know I should never assume I have all the relevant information in the message, and even basic questions can produce a lot of followup questions. I do read all the questions, and if I get the same ones over and over I make videos about it to help lots of people. Thanks for your understanding on this. - แนวปฏิบัติและการใช้ชีวิต
Very informative. Love how you explained all the different options including the hf one you didn't like. You are a TH-cam I would happily pay to watch. Your style, explanations and material is fascinating. Thank you
Thank you. Right now the plan is to continue posting my videos for free, but I started a Patreon account if you would like to support my channel. I am using that to fund the projects. More patrons means more projects. Thank you again for the kind words. The link is in the video description.
My pleasure, only just found your channel and have watched all but the lathe videos...I woodturn so will definitely being watching those and am currently without a lathe so maybe I'll just make one but probably a metal( I weld) and wood creation. I upcycle but not to your scale and am impressed and with the imagination, design and skills,that you display you should be proud of yourself and thank you again for sharing your talents.

Great inspiration and I was wondering if the connection that is related to the speed control can be monitored with a logic analyzer or maybe even a simpler way like just an oscilloscope to see what the signal looks like to emulate so you don't need the larger interface board. Thanks again for the inspiring ideas!
I’m 64. I bought a power rheostat like yours in 1979. I made a quarter over minimum wage. Took forever to save money to purchase.
44 years later I still use it and it seems as though it’s brand new.
I do not regret the purchase 😂
you are the best teacher in the world!!!!! easy to understand right to the point, no lousy music!!!! thank you very much!!!!
Gotta say, as important as it is to learn how to design circuits from scratch for custom projects, I am a HUGE fan of repurposing old equipment/electronics. You're a wonderful teacher, thank you for all you do.
Some people are born to teach. You sir, are one of those people. Enjoyed the video, now I'm clicking the subscribe button. Keep up the good work.
Thank you and welcome to the neighborhood!
Excellent video! I have a homemade lathe that uses a treadmill motor. Had to use the controller that was with the treadmill (much smaller though). Now I know how to use it without the controller! Thanks again!
That was great, thank you sir. You obviously know your stuff and you impart it in a way that makes it easily understood. Much appreciated!
Thanks Jeremy for posting this, I'm sure it will help a lot of people ! I know that it would have helped me years ago as I had to find out by trial and error.
As a side note, grab all of those MOT'S as you can because the new ones don't have transformers !
Your shop looks a lot like mine, with motors of all sizes and shapes that all come from " the roadside " ! I never could or never will be able to stand the waste that could be put to good use otherwise !
Yeah, I would be right at home in your shop because it all looks so familiar !
Thanks for sharing and take care.
Brilliant tutorials! With a teacher like you, its hard to not love those electric motors. :)
(I was looking for video tutorials about homemade EV with a 48v 1000w motor, when I´ve found your videos)
I do and will admit something you are missing something let me tell you what you're missing you're missing a ((golden play button TH-cam award)) because you deserve it so I hope you will get at least 1 million subscribers so you can be able to get that golden play button TH-cam award because I do wiring too and I know exactly know what I'm doing and you know what you're talking about I know because I do things what you do when you are very confident step by step of people that don't know what there doing ....AND YOU DESERVE THE TH-cam GOLDEN PLAY BUTTON ....
Awesome video series! I’ve learned more watching Jeremy’s videos this last couple weeks than I had in the 6 months prior. I won a storage auction and ended up with 3 DC treadmill motors, power supplies and controllers. I watched a ton of videos read dozens of blogs and found there is so much misinformation out there I couldn’t get anything going with them. I’ve built one into a bench grinder/knife sharpener and one into a ball mill since I stumbled across Jeremy’s channel. Explains it so well an electronic idiot such as myself can understand!
Thanks for such an understandable break down on so many different options for accomplishing this project. I’m teaching my 6 year old grandson how to make an electric motor and now we have moved on to more complex things and he has a complete understanding of what he is doing, so your videos help me understand things that I’ve worked with for years in a way that I can pass on to him. You are a great inspiration and an excellent teacher.
The technique and ingenuity that goes into your projects is mindblowing.
the switch tutorial was amazing, I have a friend need to have the reverse switch installed and when I tried to search on how to do it, I spent 3 weeks and most of them were talking about it, but didn't explain how to actually do it at all just talking about things it didn't help at all I figured it by myself by trail and error, but when I saw yours it was explained in like 30 seconds..way to go, keep going awesome videos
Video and tutorial aside, you are a man who is wise beyond your years.
About the tutorials though, in my generation you had to be a well behaved kid lucky enough to have a wise Ol man teach it to you knowledge like this. I think it's wonderful that you share it with so many including myself, a lifelong fixer
Definitely a welcomed addition to the previous knoledge you have played out on this channel. Thank you Sir!!
I've been wanting a belt sander and bench grinder for a while now. You've motivated me to salvage some motors and build them myself. Thank you.
Hi Jeremy. I served a 5year apprenticeship here in UK in the 60s. I have learned more from you in a few hours than I did in my whole apprenticeship. At 70 years of age I am learning again. I have rescued a motor and hope to discover how to wire it.It has 3 wires, 2 brown and 1 blue. The diagrams (2) show a capacitor to N and bl, or bl/N and sw. The diagrams show 3rd connection as vio -L1. It's a 4 pole, 230v, .4amp, 42 watt Gefeg brand motor. Model E.G. 7130 2al rl Thanks for your knowledge and enthusiasm, it is so refreshing.
I am trying to learn to wire salvaged motors and your videos are just like a teaching class :) keep up the good work!!!
Thanks Jeremy, just took apart my first treadmill today and this is a big help! Cheers.
I work at a surplus store man..can't tell you how much you've helped out with vids like this. We literally have those treadmill motors as well as others. Some with a butt ton of leads and odd connectors. Some without. It's a trip. Thanks my guy.➕💯
Good info. Helps with the current project I’m working on. Still going through all your vids. I’m certain what I need to know is there. Thank you.
Well done lad! Thank you very much for your time!!!
Your videos are excellent. I enjoy the clarity and your confidence in the delivery of the subject matter. Your projects are amazing.
thank you very much this is going to be part idea of my new proyect. from Bogota ,Colombia ,South America thank you again
You are welcome.
An excellent video. You have the knack of imparting information so that it is easy to understand. Thank you.
Great explanation! I love how you try all the options and then narrow down from there. Don't know how you find the time to do this. Thank you!
The definitive DC treadmill motor video. Thanks Jeremy. Just got a treadmill Thursday, good motor and controller. Stripped it down. Alas it didn't have an MC-60 type controller, so I will be trying out a 10000W 110v 220V SCR Voltage Regulator Motor Speed Controller from our favorite auction site for $12.66 and a bridge rectifier. It will come on the slow boat in a month perhaps. The controller that was in the treadmill is an Astar TD-3000N. Worked, but not likely to be able to hack it at my skill level. Not much on the net about it.
Thanks for the help, Jeremy. I'm designing and building an ultra lightweight pedaling electric car. It's aluminum framed, using moulded carbon fiber where key strong points are in the body and polycarbonate body as well. You are smart.
I am grateful for your videos. I had purchased a motor from a scrap store and wanted to make my own pottery wheel and now I know for sure this dinky 1/10th ball bearing motor I have isnt the right one, and I will need a speed controller for sure. I actually have that harbor freight thing too, I can see now it wont work and is basically a dimmer switch lol. I will find a treadmill somewhere and review your videos before I attempt anything. I really appreciate the time and energy you took in making these, I probably would have burned my house down or put effort into something that either didnt work or didnt work correctly. Take care :-)
Thank for making my day! I know enough about basic electric to be dangerous. I gutted a treadmill, and fabricated a nylon pulley with the lathe, and placed all the pertinent treadmill items onto the lathe, and it works! With your video, made so simple, I will go to the next steps and purchase my variable speed and reverse controls.. I may try to utilize the old Furnas A-14 Drum switch that came with the lathe, if possible. Thanks again. Best video yet!
I see others have mentioned this, but it is worth repeating; you do a superb job of explaining things. It is one of the things I like most about your videos, aside from the topics and content, of course. Thanks for all the work you put into the videos.
Thank you!
Thanks.. I'm going to use Option B with the big transformer and the bridge rectifier to breathe new life into a treadmill that I bought cheap. Great video great explanations.. I've watched loads of videos and spent loads of money so far but nothing has worked so I'm hoping this will finally get my treadmill working. Thanks again.
Great video. your method of explaining things is very good and easily understood
Thanks for the detailed lesson. Subscribed within minutes of watching.
Hey Jeremy,
Just wanted to say that I think your attitude and story is very inspiring. Keep it up!
Thank you!
Jeremy you are a smart and humble man and a fantastic teacher, thank you so much for not cussing and trying to be a cool knowitall like so many on you tube. I think maybe you are the coolest one of all.
Thank you... that means alot.
Well done again man... Seriously nice work... I don't get to watch as much of your vids as I'd like to.. Keep it up
BOY, you have been given a gift. Your explanations are, comprehensive, yet concise. Easy to understand (for me). High-tech for folks starting out in a 'one-car garage'. Am going to put my money where my mouth is. THANK YOU, my $$ support will follow my last key-stroke.
Thank you!
Great video, thank you. On your lathe, I’d suggest using a reversing switch without a centre off position.
Jeremy, what a great instructional video! You explain thing so that even I can understand them. I need to order some parts and get to building. Thanks and keep up with your videos.
Great video. I appreciate you posting this, and showing various ways to get these motors to work. Thanks!!
Great video. Thanks for breaking everything down and explaining the specs
the treadmill motors are very popular for making wind turbine. this is a great video thanks for this content.
You know your stuff and did a good job of explaining everything. I collect every treadmill motor I can get because they are so handy. I had 6 but gave two away to a friend.
Thank you Sir for sharing this information with the enthusiasts. I will really use it to the utmost to develop my ways of producing feeds for my animals in my small farm and thereby save some dollars on the feed.
I would be in heaven with all those motors right now because I'm building a BattleBot for my two sons and man these things are expensive. Great content and perfect explanation on everything very easy to understand what you are saying.
great tutorial Jeremy keep the information coming. I've learned a lot from your explanations.
Very useful information. Well worth the time to watch, if you have a "DC" motor from a treadmill,. Thank you for sharing.
Jeremy,
you just solved a problem for me. I have a 12v squirrel cage fan to use for a blower motor but it's not fast enough. I have a vacuum cleaner motor that will spin faster but I couldn't regulate it. This video showed me I could. Thank you.
Oh, If you have a electric supply house nearby get a "Uglies" book. It has all sorts of information in it for electricians. Wire: sizes-amp capacities-ohms per foot-etc, the formulas for watts/amps/volt/ohms, explanations for the markings on the wire. i.e "THNN, THHN", Motor information and formulas for power needs, and some code stuff that can keep you out of trouble too. The last one I bought was $15 WELL spent.
Great Video.. Really love the description of the transformer, the way you explained it made me understand the process which I really though was something a lot more difficult to understand.. It all seems like magic until someone can get you to understand.. Once again nice job..
Sir, I am reporting in to inform you I killed and skinned my first treadmill today and I hope to join your tribe soon
oh man you have found gold! i watched a video where it was used to switch out a drill press motor and it now has variable speeds to it. Good luck with you idea,,,,
This type of hunting is addictive....now im looking for electric dc forklift motors
sparky Mccormick BIG GAME.
Just had a solid week of hunting season (council verge junk collection). I Bagged 2 dc treadmills, an old AC treadmill, 2 washing machines and a couple of microwaves.
Very good video what is the name of the motor you used on your lathe please
Cheers wayne
Great video! Yes, the video is very helpful. I like the different options you show on motor control. I prefer the one with the Harbor Freight controller and the rectifier; I will try that one as soon as I manage to get a salvaged dc motor.
Jeremy you seem like a very cool and humble person,I bet you make a good person to know/friend,thank you for all the good content and yes it is always good true info
Thaks for taking the time to make this video - very informative, and explained well!
Love your videos...you make it easy to understand.....so informative....THANK YOU
I wish we were neighbors! I would bring your favorite drink over and learn so much. Appreciate your videos😎
Thank you so much for the kind words. We are certainly virtual neighbors now! Welcome to my neighborhood
Love your videos. Thanks for teaching.
Great video Jeremy, I'll be pointing some of our customers in your direction!
I feel so blessed to have found your website. I have watched three of your videos and am so impressed with your electrical knowledge and excellent teaching skill. What I really need help with is choosing the proper size pulley for the job. I’m starting to collect the components to build a perpetual energy machine large enough to power my home. I have been watching everything I run across on TH-cam dealing with the subject. The one I’m most interested in utilizes a heavy flywheel. A large motor gets the flywheel up to speed and is replaced with a much smaller dc motor to maintain the flywheel speed. If you could provide me with any help I would be most appreciative. In the meantime, I’m going to watch many more of your videos. Thank you for any consideration.
Your the man...I'm thinking about making a go kart and your video's are golden
Just spending a lazy Sunday binge watching your vids Jeremy. Very informative and keep it up. You’re going to grow huge. Probably just like the route you took to your Engineering job,
Thank you!
You are an amazing person Jeremy, God given talents and sharing with others. Very helpful. I am trying to figure out what I need to build to convert house current to 24 volt to power a DC motor from a electric wheel chair hub. Watching your channel and paying attention will get me there. I just found the VARIAC on eBay for $59 and free shipping. It will at least let me run the motor until I can learn what I need to, Many Thanks
Jeremey,
I have to say that you have great style, the way you explain, the theory,it all makes sense if you do not understand the principal, forget it....job well done....waiting for the next video...thank you ....ray
👍
Another well-done video with tons of great, easy to understand info. Thank you again, Jeremy!
Thank you Jeremy!
Man I really dig the way you explain things and everything that you said been helpful to me in one way or another over the past few months going to get it man that's admirable
Very clear instructions.
Good job Jeremy. Gre
at information and explained so a newbie can understand.
Wow am I glad i found your website/youtube channel. You are amazing. Your way of explaining everything is awesome. I'm a 65 year old inventor nut and I love people like us, but your way of explaining is just the best. Had I had a teacher like you back when I was in grade school, Lord knows where I'd have been today. Keep up the great work. I'm going to be trying many of your ideas and projects and I'm so thankful to have found them and you. Bravo Jeremy. This is what America is about, and this what i love about our country. Yankee ingenuity rocks!
Thank you for the kind words. I am honored you feel this way.
I agree with you Victor. How lucky we are to have great teachers like Jeremy Fielding available to so many people wanting to learn ! !
I’m 64 and relate to your story.
Can you imagine how much more we could have got done with Internet AND EBay 😂
Good info, thanks Jeremy.
Super helpful! Thanks so much for posting this!
Good stuff, thanks for the video.
very nice explanation thanx jeremy god bless you
Thank you for this video! Very helpful
Great information, I am working either fixing a KBVC-14 or getting a different one!
I started watching a few of your videos and thought you were like the Mister Rogers of electric motors. Then you go and tell Jesse Trudeau, "Welcome to the neighborhood!" ...Classic! I like the way you explain things so that even a dummy like me can understand. This is the first ever comment I've left on TH-cam. Keep it going man, it's all good!
great video,jeremy
,thank you for sharing
I'm glad I came across your channel love it.
Thank your for enlightened me,this video do help actually
been looking hard to find a channel that has a lot of stuff about different motors. great vid
I thank you for sharing so much knowledge. I now know how to make use of motor so I find.
+MarkH10 that is awesome
Sir i love your channel. Thnak you for sharing your knowledge with us
Very well Instruction!
your videos are a big help to me and thank you for your help you are grate
i remember the scroll saw, that was the video that got me to sub. thanks for these videos, i just gutted a stackable washer/dryer today for the motors was wanting to make use of the blower motor setup from the dryer it looks like it would blow some serious air around.
Great video man. Very informative . Thank you.
Dude your videos are awesome!!! I am like you in the way that I save EVERYTHING, and tinker around with it, take it apart, see if there's anything I can fabricate out of the parts. Nice work buddy!!! you definitely have a subscriber here. put out a DVD or something!!! Go Pro!!! lolol
You've got me wanting to go pick through my neighbor's pile of appliances so I can get all this neat stuff.
Have fun.
Jeremy Fielding Ok so I know this is on of your older videos but it’s a great one! I went ahead and bought the variac device, a bridge rectifier for a generator, and the large size female spade connectors. I used a treadmill on/off box and put the rectifier on a big heat sink inside with a 110 ac plug in and the dc motor connectors out.
I have to say Jeremy, this set up works great and controls the treadmill motor on my metal lathe perfectly. In the past I’ve tried cheaper solutions not the control over the full range isnt there. The whole setup was $90 and can easily be moved around if needed. I have several dc motors to set up in my shop and plan on making several on the rectifier boxes to make it all easier.
The components I used
Variac - 20 Amp transformer $71.19
Bridge rectifier - PSCCO rectifier diode bridge with heat sink $11.21
9.5 mm female spade terminals - $6.95. The rectifier has the large male spade terminals.
Plus wire and other consumables from inventory.
Total $89.35
And on the scheme of things well worth the cost to gain the desired control over dc motors.
YOU ARE A LEGEND
great job thanks easy to understand
Excellent explanaition
Yes Very Good & Helpful to me.
very good description of what each motor and what it does so thank you keep up the good work.
+dasutt1 your welcome
good job man I understand it now.
very nice Jeremy, thank you.
Thanks! Makes all this stuff seem alittle less complicated
Thank you for a this motivating video.
thanks for the videos
