- เผยแพร่เมื่อ 30 ม.ค. 2017
- I take some off the shelf parts and connect them together to make a low cost treadmill DC motor controller.
Parts needed:
4000w or higher SCR motor controller (I used 10,000w from ebay)
Full wave Bridge rectifier ( I used KBPC5010)
200K linear Potentiometer

This is fantastic. I am very thankful to finally see a cost effective, simple solution to using these treadmill motors I have laying around. Much appreciated.
I just ordered the parts for this to put on my home built belt grinder. I've been using it for about a year with the plastic console from the treadmill - which works, but is awkward in more ways than one. It's such a useful tool that improving it like this is well worth the effort. Thanks!
Instablaster.
Omg, i have watched over 50 videos if not more, digging on forums and everything to find a simple, affordable solution to this problem. Thank you, i still don't understand why others can not explain this so simple like you!
Well, I've ordered the parts to get my motor running! I'm pretty excited. Thanks for the tutorials!
This is, hands down, the best DC motor wiring video on TH-cam. Thank you sir. You have made a very confusing thing, clear.
I've been looking around for months on how to control my DC treadmill motor. This is the perfect video to answer my questions. Thank you so much.
GREAT VIDEO MIKE! It came at exactly the right time.Tomorrow a.m. I'm picking up a free treadmill to use for my 60 yr old bandsaw. (It's almost as old as I am!) I watched your first video and have been checking daily for your promised follow up one. This will be my first use of a treadmill motor for power tool operation. Thanks so much for the simplistic explanation. I'll keep watching and look forward to more great videos. You'd be a terrific shop teacher! Keep up the great work Mike!
Just hooked up a treadmill motor to a SCR and rectifier and worked like a champ- thanks Mike! Going to convert my bandsaw from wood-only to wood or metal (with the appropriate blade change of course)...
I had lot of problems with these speed controllers, but never really got the right answer. Now I know what I need to do. Thank you. well done.
honestly your such a legend mate, cant even tell you how much this helped me.
This totally worked for me. I went with the 120v speed controller because I don't need 220, and it works great. I spent around $30 because I didn't want to wait, but I could have spent much less if I was patient. I also got 2 bridge rectifiers and 2 potientiometers for that price, so I have backups. Everything came from Amazon. Thanks!!
It's folks like you who make life a little easier for many of us- Thanks!
I just did my 9'' lathe, just like you mentioned and great, it works just the way it should,'ll never go back to changing speeds with the belt changes...thank you job well done.
Thank you for posting this video.
I have collected 5 treadmill motors and was looking for a cheap way to run them. The information and part #s given worked perfect. Now on to powering some shop equipment..
Thanks for sharing
I hooked mine up today with the parts you suggested and it works GREAT, Super easy to do. Thank You
Talk about simple.....and cheap. Thanks a million for taking the time to go through the setup. I'm not sure you could have made it any easier to understand. Great video!
Exactly what I was going for. Thanks for watching.
I second this.....really straightforwardly Simple.......Thanks for this Video.
Hi, Thank you for showing how to hook a controller to the motor. I used the same setup as you, and now have my Craftsman table saw up and run with it.
Thanks Mike, worked great! I used a different controller (P/N 090456) and the potentiometer that is already installed on that unit works great. The first 1/3 turn does nothing but after that I get full variable control from very slow to top speed and everything in between. I also mounted the rectifier on a heat sink from an old dell PC, not sure if necessary but using on a lathe and just want to keep everything cool. Excellent video Mike!!
You should be able to get that full range back by adding a resistor to one of the leads going to the pot. Just use your dmm to get resistance ohms just before it starts spinning. Lets say its 200 ohms.
Just add a 200 ohm or maybe 180 in series with one of the wires going to the pot and you should have mostly full range back.
THank you! I am planning on building pottery wheel from a treadmill motor and this is hugely helpful.
That will be a fast pottery wheel
You just helped me get my gingery lathe motor running! Thank-you!
I've been searching for weeks to find the solution that you've just explained. Thanks very much!
Just what I needed, I ordered the parts already, many thanks
Mike I just want to thank you for this information. My kid start to play baseball and he like it alot
He ask me to build a pitching machine and one's I saw the video
Man was game on I build from scratch a pitching machine that pitch 60mph thanks for this valuable information. I appreciate it.
Great video. Straight to the point and the detail that a lot of us appreciate.
Cheers
Thank you for sharing, it really helps to know that the processes does not have to be rocket science
this scr controller will eliminate those hideous super huge and hard to dismount treadmill boards
thank you for this golden tip - great job 🏆
very good info. ive been converting my tools to dc treadmill motors and your setup is axactlly the combonation i have been searching for. forget those damn treadmill controllers. now i know how ill be doing my band saw, drill press. i never knew that changing ac to dc was as simple as that $5 Rectifier. you just made my project go much smoother. thanks man. you earned my sub
thanks for the video .I bought all the parts you mentioned and have just put it all together and it works a treat .Thanks, had cooked the main board and needed a cheaper fix, makeing belt sander
Mike, you did a great job on the videos showing how to use the DC motor, you showed me that I remember more of my electronics I learned but never used in the USAF. Aircraft maintenance was a case of drag it out of the rack and shove another one in it's place and send it back to the factory to be repaired. That 22 weeks of basic electronics school was a waste of time!
An idea for another video, figure out how to get the stepper motor from the tilt unit on the treadmill to work. I would like to put casters under my wood lathe and use the tilt unit to lift the lathe off the floor. I have a bad back and can use some help.
Just found this video and its exactly what i have been looking for. its the best and simplest instructions i have found yet. thank you very much...now, to order some parts.
You are one sharp cookie, thanks for the knowledge!
great presentation! and the nice job on the potentiometer upgrade for increased resolution.
Subscribed. If all your videos make things this simple I'll be with you for the long haul. Thank you.
Cheers Mike, based on your vid i just made my controller for my grinder. Great info for us noobs
Caution: a brushed a/c motor such as in a drill is intended to be variable speed. An induction motor such as the band saw example is dependent on the 60 hz frequency for it's speed. Reducing the voltage to an induction motor lowers it's torque but not it's speed. Brushed motors using this setup should work ok, but notice the band saw (induction motor) lost power and only slowed when torque fell so low it could no longer turn. D/c motors do need the rectifier as shown to produce pulsed d/c. Excellent video, I have 2 treadmill motors and 4 power chair motors to experiment with.
Thank you for sharing this information, it was just what I was looking for! Subbed.
EXACTLY the information that I have been looking for. Well presented. THNX!
same!!
Hey Mike thanks foe the informative vid. I'm in the process of doing what you did here. the one thing in the video you did not reveal is what size of potentiometer did you end up having to order to make the motor work correctly? 400k is too big and and 100K was too small I gathered that much information but what size did you end up ordering?. PS I have the exact same motor as your video.
@@page76metalcraft19 200k linear potentiometer
@@supurbian How's that holding if you go to low it will burn up.
Same here
You saved me. I disassembled a treadmill for a sander project. I then dropped the Mc 60 control and when I pulled it back in it fried. $15 is a whole lot easier to take then a new/used mc60.
Hawk 1911 i
Update, the controler I bought last all of about 5 minutes and then would only run on full blast. I have now purchased a Harbor Freight router speed controller and keep the bridge rectifier seems to be holding up better.
Hawk 1911 is it still working I’m about to try it
Thank you, just tested this all out, 20 minutes and it’s perfect. I’ll make it look nice later. Good video!
Fantastically clear video, thank you so much. It really works!
Thank you so much for the information. You definatly saved me alot of time and headache
Thanks Mike! I have a treadmill motor with all the control gear with it. Ill get one of these and throw the other junk away.
Great vid, had no idea how to go about using a tredmill motor. Thanks
You just saved my old '90's Craftsman lathe with a 90VDC original motor with a blown controller. I think it works better than the original. Thank you!
I got one of those craftsman 90vdc lathe motor too and was wondering if you had to modify any of the parts or setup?
Thank you very much 👍 I've ordered the parts listed, going to give her a try. ☺
Excellent video and the information is absolutely invaluable. I haven’t got a chance to watch all of your videos but the two that I did watch has helped me tremendously. Thank you and I hope you have a wonderful Thanksgiving. God bless you
Sir thank you so much your information was valuable I was able to use an old treadmill motor to operate a shopsmith 10 ER lathe. I purchased the parts that you recommended and this thing works beautifully now I can control the speed!!!!
I accidentally fried my treadmill controller, and this is the perfect solution!
Thank you
Hello , Did you manage to fix your treadmill using this option? My PCB circuit had failed but moto ris good. Please advice.
What the parts are, HOW they work together, an alternate or two for each choice (and WHY ! ) and how to find - and cost for -
parts, EXCELLENT WORK ! Personally NOT _so_ interested in shaving 1 or 2 bucks here and there, but for those ( us ;-) ! ) on a tighter budget, we're up & RUNNING ! Thanks !
Outstanding, well done without bs
That absolutely works 100%! I'm going to gobble up all the treadmills in Oregon now.
Thank you very much, I've been searching for a video like this.
Thanks for a great idea! Works like a champ.
EXACTLY the information that I have been looking for. Well presented. THNX! for me too...... so powerfull treadmill motor
Hi Mike, finally got all the parts together and it works a treat👍👍👍. The potentiometer that came with the controller seems to work quite well so I probably won’t change it. I couldn’t for the life of me remember where I put the bridge rectifiers I bought so I used the one I found on the circuit board. Next job is to mount it in all control box. I will also use the iron ring on the wires as well as the power filter that came with the treadmill. I don’t know if the filter is necessary or not but as I have it I figure I may as well use it. When ordering the bits and pieces I took the opportunity to also order a tacho so that will also go in the control box as well as an illuminated master on / off switch.
Thank heaps for your very informative video. Cheers Stuart 🇦🇺
Hi Stuart I see this is an old post and assume by the flag that you are in Aus. Do the items listed work with 240V and if you have any details about the motor or parts I would be really grateful. (not savy with electrical gear) Cheers mate Ray
well i finally got it working, trying to be clever i bought a controller different to the to the one mikemanmade used, i sent off for the same type from china and hey presto worked straight off, i have two motors , one 130 volts, one 180 volts, the 130 volts pops the fuse at high end but the 180 works fine all way round to the top , plus the 180 works fine for variability with the original pot , thanks mikemanmade i can now move onto making the grinder frame
You sir are brilliant!
Thank you very much. You make it seem so simple and it is simple.
thank you so ,much for doing this video. these motors are awesome...im going to put one on a vintage drill press.
Pumping the output of that triac straight into the motor was just scary. It'd be like plugging straight into a 120 volt household circuit - a plan that needed work.
But live and learn. Sharing the mistake makes it a valuable one. For that, many owe you thanks.
I made it, values given are good. I ran with no load, nothing got warm. I did not put a meter to anything, maybe later. Thanks Mikemanmade.
Thanks for sharing your setup, before I finish watching the video I went on Amazon ordered 2 of the same setup. Came in at right at $40.00 but it will be giving me 2 3hp motors to use. Thanks
this look like ive been looking for, thank for the idea . great video
Hey Mike in your test with the 10,000w SCR were you powering it with 120v? I ordered the 10,000, and I only plan on using 120, not 220. Think this will work? This video is exactly what I've been looking for!!!
Excellent info. Thanks for sharing!
well explained...thanks for uploading such useful video
GREAT VIDEO MIKE! THANK YOU
great info. I have a 1 yr old treadmill motor and speed control board and controle board. Not crazy about the soft start that is programmed into the sc. This SCR/Bridge rectifier seems like a good change.
built 3 of these things now, and converted my Craftsman Atlas 12" lathe and my little Atlas 618 lathe to treadmill motors with these controllers. Added a tachometer on them also, dirt cheap.
Great video, thanks. Best part is ditching the soft start. This makes DC conversions so easy.
awesome. But back to the potentiometer. good info. Just started using some of my recent China parts and potentiometer is on my short list. nice to know that rectifier is over sized in that small package.
Awesome tutorial! 😃👍
Great video, very helpful.
great explanation...i've been wasting time looking for and all and one ac to dc controller that would actually power 700 watt motor
thank you, i have been looking for a video like this. thank you thank you tgank you
Glad I could help you out!
Just tried this out, and I gotta say, so far this works. Thank you so much! My original treadmill board was neither an MC-60 nor a MC-2100 or anything like that, and I think it was fried anyway. This will make things just so much easier. Ran it for a few minutes, no load, and no magic smoke. Rectifier was just ever so slightly warm, so no danger of major heat buildup that I can see. Only real testing under load will really let me know. However, I'm only getting a little more than half the dial in adjustment on the 200k pot. Should I try a different size, like a 100k?
USE A HEAT SINK
Searched for something simple like this for my 2x72 belt grinder for quite some time. I did everything to the T, part number match and all. I noticed at first that noticable torque was lost and 2 minutes into some light grinding the motor started to release the smoke. cheap enough to buy, decent amount of effort to put together and package nicely but it was worth the try
I love you so much right now! Everything here is available on Amazon. Think I paid maybe $30 for this build. All available on Prime.
Thanks, built it, works great.
i bought all the shit in the decription and did just what you said and it worked! alto not very long. i dident have anything held down and the motor vibrated over and touched sometin id dident like cause there was a small flash and the fuse blew. but that was my fault. tanks again. it works!
mike mabie u can help me. i took my old fuse to the store to buy another one but i lost it some where. do you know what size fuse it has. i bought the 4000w model with the 4 wires like you said. im pretty sure i seen a 20 on the fuse somewhere but im not sure if that was amps. that seems like alot of amps for a fuse that small
Mine was f20l250v which are 3/16 by 3/4 tiny fuses. I had to order online to find more. 20amp 250v
@@rustybrowneye hey I think my fuse blew too.
Excellent this just helped me loads I have an old lathe I inherited that was one speed even better the motor is ac
Thanks Mike that's awesome!!!!
thanks for explaining that. wish i had the info like a week ago
Excellent video. Subscribed.
Fricking awesome. I just got the parts in today...badabing...works great. Thanks a bunch. I already have one of these running my lathe...but with a commercial motor controller. I used a treadmill board to control another motor on my drill press. BUT...I had another motor and a fried controller from the treadmill. This make that motor work great. Only problem is....the motor spins at 6500 RPM!!! I'll really have to gear things down. This isn't the fault of this controller....its what the sticker says on the side of the motor.
Ha! Best of luck!
good night., i'm from brazil and i love this video, i have about 10 of these engines saved, i will do all of them, thanks
.
Excellent vid Mike...wondering if the potentiometer range may limit out early once under load? More testing may be required or do you have a way of estimating from your previous build? Thanks
Can't get motor boards for mine anymore. This video saved me over $1,000 in hauling the old and buying new.
Great job!
How do I get the drive wheel off the motor without damaging either, and where do you recommend I get a wider drive wheel for a 72 in belt grinder. Thank you.
On the back end of the motor there should be flats on the shaft that you can put a wrench on and hold the shaft from moving. Then while facing the front end turn the flywheel counter clockwise.
It is a very great helpful video
Great Video
Thank you for this tutorial!
This is amazing, thank you
Good stuff. I need to copy this for a corning machine. I need high torque and variable RPM. This will work perfectly.
I tested the 180 volt DC treadmill motor with my dewalt 18 volt battery! An AC speed controller with a kcp5010 bridge rectifier ( 50 Amps at 1000 volt peak! ) works like a charm. Lol
This isn't a constant rpm driver is it? When you put load on the shaft it'll slow down right?
Awesome work ! that is such a gat price to get rid of all the board controllers from this treadmill and even at $20.00 that's a great deal because I payed $25 for the treadmill
Ok, so we can say that's kind of VARIAC ??
I'm really looking forward for a voltage regulator like a transformer or a VARIAC.
You are saving my life dude.
I'm using a 90VDC motor like that one and it's 1.5 HP it's possible to make it run?
and i wanna ask you about the peak current of the motor
built something similar with a wall light dimmer switch, a bridge rectifier, and a capacitor to run a 90vDC motor. it came on about at about 1/4 turn and topped out near the end of the dial. your method looks a bit easier. although i've found some DC motor controllers on ebay for 10-15 bucks now.
