How To Turn Any Motor Into A Servo Motor (#075)

I turn a treadmill motor into a high powered servo motor, to add lathe functionality to my CNC machine. This video shows you how to do it.

Imagine taking a college course with this guy as the professor. Talk about getting your monies worth. So much learned from Mr. Fielding videos. Thank you so much.

Who needs college. This is what I needed growing up. I'm 49 years old. Now own my own machine shop. I learned everything I know in tool and die works, own my own. rolling up my sleeves and getting dirty. I have always wanted to learn the electronics side of things to build my own machines. That is now possible. Thanks to YouTube and this good gentleman Jeremy Fielding.

1:34 "So let's make a servo motor out of this treadmill motor ... OBVIOUSLY!" I don't know why but that made me so happy.

I just watched your newest vid with the cnc table saw and then this one was suggested.

Man, as a recovering addict building up tools for my little apartment workshop from nothing, I’m so jealous of your shop and tools. You’re living the dream, making all this cool stuff. I hope to get there someday soon.

Right now I’m still in the “search through trash to find stuff to tear apart so I can hoard the components for later use.” Phase of things.

This is the stuff that makes me feel better about the internet spreading stupid stuff like antivax and flat earth. You are spreading high grade engineering information to the masses. Great work as always.

I worked in the electrical field for 30 years. I love watching videos from different people in the field of electricity and electronics. I don't understand why I just found your video collection...Well I just subscribed !! Keep up the good work.

One of the smartest engineering presentation he delivers in the YouTube.

[joeycmore]

America is built on this sort of ingenuity and this man is a genius!

[EdgarInventor]

Gifted guy, to an inspiring level. We need more of these...

[CCCfeinman]

Great video! You didn’t shy away from the necessary compromises, or excuse the experimental nature of this project. This, IMO, is engineering at its best.

[mark-wnek]

I think I've stumbled onto a genius in action. No hyperbole, no bs....just useful, understandable information laid out in layman's terms and enjoyable to watch...and LEARN. Thank you very much.

[skewedmaker]

I have only done a few projects with toy servos, so this was a fascinating lesson on the mechanics of servos at a larger scale. Thanks!

Outstanding video yet again. Very few people on YT seem to be willing to actually 'Make' something vs just videoing some bits or bobs they've bought. These are the types of videos that inspire people to experiment with 'junk' and learn to do cool stuff. Keep up the good work.

I have the same servo drive on my retrofit milling machine. Use the servo tuning software to help dial in the position holding. This will get rid of the annoying buzzing noise. Awesome content!

[christopherrasmussen]

I have had a bare (cutting) plotter for years (with servo motors). Good buddy of mine sent me a servo controller, power supply and software. I have been staring at it for several years. I think during this time of 'trouble' while I hunker down I will try it. You made so much sense. Thank you. Stay safe!

@Jeremy Fielding why hasn't YouTube led me to you much sooner? I'm so glad I found you. Your material is gold ✨

[dasibaho]

I would have loved to have you as a teacher when I was in high school 25 years ago... I really love the format of your videos. No music, no bullshit, just technical knowledge transmission. Thank man 👍🏻

Jeremy, you asked for comments. Here is mine. As a physicist who has worked in industry a long time in R&D and various engineering roles, I'd like to offer the following feedback: Servo motors exist because they can do well what non-servo motors cannot do well. They are engineered to handle the demands of the applications for which they are intended. True, one can make just about anything do something similar to something properly designed for a job but it won't last. You cannot simply sidestep the physics and engineering that goes into building proper motors for the demands of the intended application. To Jeremy's credit, he acknowledges this up front. That motor will burn up if used this way except in the lightest of loads and low duty cycle. This is a very informative overview of how these kinds of closed loop systems work. However, you cannot simply make a motor designed for a specific application play nice in an altogether different application by trying to make it act like the appropriate motor. Except in the most general sense, they are not that interchangeable. This is why there are complete industries that revolve around different types of motors. You could argue "That's nonsense and hype for the sake of revenue generation" but you'd be wrong. Motor design is very application specific and rightly so. There is a right motor for every application and one should seriously consider the long term cost/benefit analysis when it comes to the investment. Sure you can cut corners and try to make a motor do what it was not specifically designed for (and watch it under perform and eventually fail) rinse and repeat, or do the research and buy the right motor once and be happy for a long time. Of course there is a lot of good learning that CAN happen if one pursues the trial and error approach and if that is what one wants to do for the sake of tinkering then heck yes, forge ahead. However, if you have the math competency/comfort and a technical inclination, spend some time reading up on motor designs and their applications. It could save you a lot of money in the long run. Whichever path you decide, I wish you a pleasant journey! Peace all and Jeremy keep up the excellent channel!!

Thanks for a great video! I like how you use readily available components to employ in a wide variety of applications and explain the function of each component as well as alternative approaches. Also providing details such as wiring diagrams, component sources and warnings really help to let your subscribers duplicate what you are demonstrating. Awesome!
