I salvaged the motor and speed control from a used treadmill. With a small modification, I was able to simplify the electronics for later use as a variable speed conversion for a fixed speed motor power tool.
I removed the bulky control interface and replaced it with a 10K ohm potentiometer.
I also show how you can reverse the direction of the motor and also stop and start the motor without having to constantly adjust the potentiometer.
I posted a follow-up video that talks about the coil and attempts to see what it does, performance wise:

Clear, concise and well explained with good videography. Exactly what I needed to learn how to factory delete the unwanted bits from a treadmill motor salvage, or add in my own.
10/10 well done
Awesome video! The tip on making the motor start and stop at the same speed is a lifesaver.
Thanks Barry.
I'm just doing my lathe conversion and this is the best video that I've seen for a treadmill motor conversion. Very well explained and some of the other comments will prove useful too.
Thanks for posting this.
Excellent! Precisely the info I needed, in a format that makes it easy to do step-by-step following your instructions. You've created another Barry's Workshop fan here in Florida!!
Thank you very much for you kind comment! I'm glad you find the video useful.
I am doing this conversion right now to my late 50's Rockwell Delta 20" wood cutting bandsaw. I am converting it to be able to cut metal. That red wire tip is great!!! Without the red wire tip, I would of bought a 6k SCR. The soft start I don't mind so much on such a big bandsaw. Thanks for the vid.
Thanks. I've watched many videos on how to do this and this is the first one I have seen that show you clearly how to do it. Happy days.
Using Barry's video, I was able to set up a treadmill motor onto my wood lathe and now have a forward/reverse switch and variable speed. Very satisfied with the comprehensive info on the video. Thanks
Hi Barry. I like your simple, straightforward, relaxed style and delivery and the thoroughness with which you approach the subject so methodically. I've learned a lot, not least of all how to approach stuff like this myself.
Many, many thanks to you and very best wishes with your Channel.
Worthy to subscribe to. You won't run into folks like this everyday.
Clear, concise, simple no rush explanation.
Thank you for who you are.
Had an older, but low mileage Image treadmill. Sat a while plugged in but powered off. I had laid a coat over the control board, and when We went to use it the lap indicator was on without the dead man key inserted.
Must have overheated the console, as it was DOA. No schematic so contacted Icon fitness...useless!
No parts available so I started searching the web and found Barry's video. Had an old 10K pot and wired it in and bypassed the power board. Works fine. No display but it works and the boss uses her Fitbit for mileage.
Thanks Barry and will stay tuned in.....Bob, Milwaukee
You made my day! Thanks for letting me know that this video helped you. 👍
The most comprehensive guide on the issue! Really appreciate idea with red wire disconnect!
Awesome!! Thank you. It helped me realize what I was writing incorrectly. Mine is working like a dream now!! $4 potentiometer and a free treadmill! Money well spent.
That was awesome! Loved the step by step walk through of what each piece does and then the change over right then and there of the wires!!!
Most helpful video I came across so far regarding treadmill motor. Thank you Barry
Great tutorial. Really appreciate the time you spent on all the details. Recently, found the exact same control board, but with a different motor in a treadmill up in the hills near my town. Sadly, the inductor had a bullet hole in it, so I couldn't use it. Please consider making a shop tool from your motor and record your adventure. Cheers brother
I found a free Treadmill and everything that I needed worked. The parts were all very similar to those in this video so after purchasing a potentiometer I was able to do the same as Barry did. So for the price of a small burger I now have the motor I need for my belt grinder project. Thanks for the tutorial! Now to get a drive wheel put on the motor....
Excellent! Thanks for sharing.
A huge THANK YOU.
I got my hands on some treadmill guts and was looking to convert them. It just so happens that it's the exact same hardware that you have.
What kind of treadmill was that? I'm scouting for a donor, not sure what to look for. ~2 hp would be ideal.
@@ptz0nPro-Form CrossWalk Advanced 525x. I think the motor said 2.4 hp. It's got some kick to it.
I slapped a 10k pot and switch on it just like in this video and it works exactly as advertised.
Needed to know about how to reverse my treadmill motor and you explained it beautifully. Thanks. And the other info was a bonus thanks
Great tutorial. I am struggling with the same setup for a lathe right now and was just gonna go back to a 120 volt motor but i think this will work for me. Thanks for the great video.
Wish I would've come across this video before I did my mill conversion!! Oh well, good video and thanks for sharing! If you run your DPDT switch for reverse, it also disables (bypasses) the soft start function for restarting at the previous rpm. I pretty much use that as ON/OFF switch after initial power up of the machine. I'm sure you know this by now, but might help the two people that read my reply lol
I have the same gear that I salvaged from a treadmill. Thanks for clearing up the “on”, “off” quandary. Now if we can just deal with the annoying delay before it initiates the stupid “soft start.”
Magnificent presentation ! Best yet on this subject .
Excellent and very informative. Thank you Barry! A tip of the hat to this instructional and most helpful video. Cheers!
Very thorough explanation Barry. Thank you kindly 👍🏻
Thanks for the lesson. I learned a lot and want to have a variable speed reversable drive. You covered it all!
Coolest treadmill motor tip ever! Thanks much.
Thanks for a GREAT video! I was looking for a bypass for that clunky control board and this is it. I happen to be working on a project with the exact same parts from the same treadmill. Ordering a potentiometer now.
Great stuff! And exactly what I needed for my power bead roller conversion! Thanks!
Great video to help others make a positive change rather than a band aide to face the same issues at a later date. I turn large wood for bowls Maple, Walnut, Pecan, Hickory. I used the old bed to mount my fishing rod turning machine I made. Perfect to sit wrap rod eyes and apply the finish. Thanks.
Thank you, Steven.
THANKS, Barry!!! I did Not know about the red wire trick to get around the on-off-on quirk. I'll still make a microcontroller do the work for me, as it can track RPM and make for a nicer display layout (and I'm just geeky that way...), but now I don't need a separate high power MOSFET to turn power on and off! Great video!
Thanks very much for the video. Best one explaining the work and connections of these components. I set up my 72" sander and is working very well. Regards from Panama City, Panama
Excellent! I'm so glad that your sander is working, that you found this video helpful, and that the video found you in Panama. Thanks for taking time to let me know.
I hope your YT channel provides you as much wealth as this one video does to your viewers.
Thank you very much!
Best video explaining how to hook this up. So much thanks!
Thanks, Chris! I'm glad you enjoyed the video.
Thanks for this very well presented instruction. Made my project much easier to start.
Great info, nothing extra! Can’t wait, I’m building a band saw and lathe. Just the info I needed.
Having a lot if concussions, (and only 1 functioning arm) I've come to accept that my brain can not do electrical.
I've burn 2 motors now trying to make a variable speed drill press. Adjusting a belt is a nightmare with one arm. I broke a tooth, (in my mouth... not a gear), last time lol. So I keep my drill press on low speed 24/7.
Now, with that said.. this video was the most detailed I've seen as of yet. But I'm at the point where I'm just trying to find someone to sell me a pre-wired system they've taken from a treadmill and built it the way you did. But no one seems to do that.
So thanks again for the video. Very well done!
Amazing! Perfect video and description for what I was needing
Thanks for the video,, great job. I am a novice at best with circuit boards but I followed your steps and am ready to mount the motor and control board in a box and hang it off the lathe.
Thanks for your comment, Joseph. It makes my day that this video helped you!
Was very useful. Thank you.
I look fwd to hearing more from you.
Best video out-there! Thank you!!!
Very good explanation on the electronics understood very well thanks
EXCELLENT! I'm tearing down a treadmill to use the motor on a lathe! THANKS!!
Thanks for letting me know you enjoyed the video. I hope your project goes well!
best video i ever seen,it explains step by step everything unlike others,thank you
Thanks for the encouraging comment. I am glad you enjoyed the video.
Thank you for saying the 10k potentiometer I couldn't figure out what I needed
That was brilliant Barry!
So helpful!! Thanks, Barry!
Very helpful Barry Thanks!
Awesome video. Agree with many other comments... very clear with extra optional features that could be done depending on the application! My son and I are using a treadmill motor to drive a DIY BB gun shooting range project and this will help us with the simplest way to modify the treadmill motor/controller card. Thanks!
Oh geeze! I just finished watching the entire video...just when you think it couldn't get better, he also solves the reset to,restart prob. In seconds
Thanks for such an informative video.
Very good video and explanation of the controller board and how to hook it up. Thanks
Very good and useful video. Thank you!!
great info!! Now just need to find the parts!
Thanks. I literally found this treadmill on the side of the road, which was just luck. I have found some deals on Craigslist that looked they would be good candidates for under US$50. Look for one that works but is need of non-relevant repair like a busted display, broken incline control, missing "key", etc.
Also, before you drive to pick it up, do a search for repair parts for that specific model and make sure the one for sale has a comparable controller and motor. Some models have integrated controls and variable speed controllers that would be more complicated to convert than the one in this video.
Good luck!
thanks Barry i really appreciate you showing us about that
Thank you for all the detail. I want to convert my wood lathe to variable speed.
This is useful fior my projects. Thanks.
Very helpful. Thanks man!
Thank you very much for this video it has answered all the questions I had, and a few I never thought about, I’ll be using all the options you explained.
Here comes the motor for my boat.
How did the boat motor turn out?
Thank you for information. It's very informative.
Thank you for the blue tape on the motor pulley. I've watched a lot of videos where you can't tell if the motor is even turning.
Thanks for noticing that. I agree that it's hard to seen on video without the tape.
This is a very informative video. Thank you so much.
Thanks for really explaining what your doing very well! A lot of youtubers are not good communicators. I'm sure i'm not the only one that feels this way. Again thank you! Oh and i did click the subscribe button! :)
Excellent, presentation Innoway I can understand completely, you now have a new subscriber. .Wish I would've found this stuff before I ordered my converter for three phase. I'm going to search for a three horse treadmill motor and put it on my Bridgeport M head on my brown and sharp model #0. You're awesome my friend thank you.
Careful with that. The mosfets on the controller board are chosen to handle the current of THIS motor. Bigger motors require more current and in the attempt to supply increased current, your mosfets would more than likely die.
Now I need to hit craigslist to find a free treadmill! Nice video!
Awesome video and details.....I got a donor treadmill tonight and just pulled all the equipment. I will be watching your vid thru my build!!! Hopefully my video inspires others as your did me. Thanks. New Sub!!!!
Awesome note. I'm so glad that this video inspired you. Thanks for sharing!
Quick everyone! Throw out all those other " plans" to do away with speed controls on treadmill mills! Finally a NO b.s. approach TO ACTUALLY MAKING IT WORK!! And for that Barry, thank you SO MUCH! Yah, treadmills are a no Brainer, they are free,unless your in a hurry,and power? Awesome!
Very good. Thank you!
Wow! Thank you; excellent presentation.
Thank you for your kind comment. I am glad that you enjoyed the video.
Good vid man. Really helpful stuff here.
Thanks for the feedback. I'm glad you found it useful!
This was very helpful to me and answered most of my questions regarding this particular treadmill motor. I have exactly the same one and I was wondering what to do with it. It seems like it is way too good to just throw away.
Thank you Barry-Excellent
Thank you very much for the nice comment.
Obviously an older video, but the information is still useful. I have basically the same treadmill circuitry that I just removed from an older thrown out treadmill that still worked. And when I see such road side trash, I have to pick it up for the motor and circuits. And so far the ones I picked up all worked or needed a bridge rectifier replaced to work perfect... Go figure... Thumbs Up!
Excellent video
Great video I'm planning on using a treadmill motor for a 2x72 belt sander.
Awesome video. Getting prepared to build a 2x72-in belt grinder and this video is the absolute best one I've seen on the practical aspects of converting from the treadmill to a shop machine. Great job!
all great info, thanks
thanks . . . very helpful
Thanks very much for the video.
thanks a lot for the video it was very well explained 👍 👏 awesome
Thanks for the
Excellent video ty 👌
To that's was a great video. I want to put one on my wood lathe and you helped alot.
Very helpfull! Thanks.
Informative Thank You
Great video thank you.
Gold information 👍🏻
Great video,,, Thank you
I just pulled the motor from one exactly the same..been out in the weather and the motor controllers look pretty nasty..left them in thinking i would start from scratch on a controller..its late and raining but in the morning i am going out and grabbing that controller cleaning it up and gonna give it a try..all your tricks are great gonna stick it on a 2x72 belt grinder ..then start on the real nice treadmill i have inside..lol
Great video!
Very, Very, Good Video... Thanks...
Great video
great video! thanks!
Thanks! I'm glad you enjoyed it.
Great Video.
Thank you very well done
thank you for sharing
Extremely informative. Thank you!
best one yet thank you ! do i need to cool the motor if running at low speeds?
Thanks so much for your kind words, Andrew.
My motor is externally cooled, and that's accomplished by the fins on the flywheel. If I run it without the flywheel, I'll need to come up with a separate way of cooling it. I'll either attach some fan blades to the tail end or just mount a small muffin fan that runs whenever the power is on.
I presume that if the fan is connected to the motor, then the cooling will be proportional to the speed of the motor, so while there will be less cooling at low RPMs, it will use less power and therefore produce less heat. This is an assumption, of course, so definitely verify by monitoring temperature under load.
Another thing to consider is that the motor may have less torque at lower RPM, so if you regularly want to use with a slow tool RPM, it might make sense to use gearing (or pulleys) to have the motor spin a bit faster while the tool is slower. Assuming the fan is attached to the motor, this should provide appropriate cooling. Although it seems to limit the benefit of variable speed, a lot of lathes have two or three ranges based on pulley settings, for this reason.
I hope this is more helpful than vague. There are a lot of variables to consider.
Thanks!
Excellent ...
Just the info I needed.
Thanks Mitch. I am glad you found it helpful.
Thanks for the great video! How can I close the circuit that the treadmill's red safety chip interrupts? One wire connects directly to the motor and the other to the copper coils...
