- A friend saved the motor from his old clothes dryer. Figuring out how it's wired up, and showing where I have used a clothes dryer motor before to build a dust collector.

Don't write off those red (heater) wires too soon - might be very handy to have some way to signal/switch something on _after_ the blower/motor gets up to speed. Ex: Maybe run the sander motor through those wires. Now the "On" switch results in a sequencing of blower first to ensure dust mitigation, then sander to do job.
I did this. When i made my wood table saw, i used one of these motors (from a much bigger unit) and wired the vacuum cleaner to start through them. It's in general a good idea to never cut wires that aren't specifically assigned to something you can't use, you never know when you might have an use for them. I just tie them up neatly, and then put a ziptied bag over them to keep dust out.
I was thinking the exact same thing as soon as he described it. Lots of possibilities there.
He didn't cut them I think... Just removed them from the plastic connector. He could reinsert them I'm thinking if need be. I just don't see him overlooking that
@@jimsjacob Yeah he just depinned the connector
False alarm guys.
THANK GOD!
That simple cutoff switch made of bent wire that lets the motor detect if the belt is intact or not is quite clever. My drier doesn't have anything like that and once announced its broken belt with what I can only describe as the screams of a hundred rubber chickens in a cement mixer.
This czcams.com/video/khOfSVULtsU/video.html is of course what rubber chickens _should_ sound like.

Retired appliance tech here- the BEST way to remove those type blower wheels is to lightly clamp your vise grip on the motor pulley where the belt goes(so as to not dmg the ribbed pulley with the vise-grip teeth), then pinch ONE fan blade and swing the motor rotationally till you have the vise grip as far as it can go the one direction, then give a quick WHIP the other direction while still pinching the fan blade and let go at the last second and when the vice grip strikes the table (or the floor pan, of the dryer) the fan wheel spins right off as the vise grip comes to an abrupt stop - works like a champ EVERY TIME, and you'll never break the plastic fan when changing a motor
Yep! Same principal as an impact gun. :) Auto mechanic here. Very often a rusty bolt will break if it's loosened with a steadily applied torque such as via a plain socket wrench or breaker bar. In contrast, the fast impact action of an impact gun will loosen the rust and give it sharp rapidfire taps that eventually work it loose intact. Ford made an engine in the early 2000s called the "3 Valve Triton." I believe it came in V8 and V10 flavors. Anyway, they used this bizarre long sparkplug that was a bad design and it would get carbon fouled and rusty over the years until it was FIRMLY stuck in its hole. I ain't kidding either when I say they get stuck, that's S-T-U-C-K, stuck! The best way to remove them is with an impact gun while the engine is piping hot. Just get the strongest and smallest 1/2" impact you got and the tightest fitting extension and socket you got. You just make pretend that you're an F1 driver and take the truck for a race around the neighborhood, then immediately slam the plugs out with the impact without mercy. If they break, they break. 🤷🏻♂️ The ones that break were always going to be hopeless. They would've broken no matter what, especially with a ratchet. The extractor tool that gets broken plug bodies out of the hole works pretty good. Usually you'll get 5/8 or 6/8. The back ones are the worst. The impact action is critical for the job. You may think it's horrifying to imagine putting an impact on a sparkplug, but it's the only way to avoid an 8 hour book pay nightmare.
Damned Maytag have a small belt making the connection.. That trick will help with some but not all my stuck fans
@@mannys9130bro, I am dealing with this problem! I got a damn 2003 Ford Expedition that I need to change plugs in 😢 what is the tool you speak of to get broken ones out cuz I’m quite sure it’s going to happen 🙃
”… so I have one, when I need one.” Exactly! I often get questions what I’m going to do with a lot of stuff that I “save” and I give the exact same answer. Some people confuse it with hoarding, but it is completely different thing (which require a skill) to understand what things are valuable, hard to make and hard to get (even if it can be a cheap thing), and also the value of having things to “browse” to help in a development process.
I’ve always been proud of a clothes dryer fix I did many years ago. It was just a belt replacement but I couldn’t find the right sized dryer belt. Instead I found an old ford escort timing belt that fit, still running solid! #improvise
That was my experience as well. I suspect manufacturers tend to use whatever belts are the cheapest at the time to benefit from the economy of scale. They don't really make a secret of this, but they tend to list such parts with custom SKUs to make them seem like proprietary parts. My dad once tracked down a belt replacement from a car parts dealer just by showing them the broken belt, they measured it and found something off brand that was functionally identical. 12$ vs the $50-$100 asking price for "geniune" replacement parts from amazon and specialty suppliers.
I used a dryer motor with your strip sander V1 plans. Has worked well for many years!
Interesting video. I have two motors that I need to use for something. Will check the wiring on my motors to find the correct power one. Hint for removing the fan the square in the center of the fan is for a 1/2" drive ratchet and extension. Easy peasey if use the ratchet.
Yeah, I was wondering if that was 3/4" or 1". But same thing, the square is to get it off and on.
(And saving motors is awesome! Fixed my own furnace years ago when the blower fan gave up the ghost on a Friday night in January in Winnipeg! I just _happened_ to have a used replacement in my garage salvaged from someone else who had recently replaced their furnace.)
I’m the same way with motors. I can’t throw one away even though I probably won’t use it. I have dozens of them lying around in my garage. It’s some kind of weird compulsion. It even pains me to toss out a junk motor. I have the same compulsion with gas cans, computer hard drives and almost any tool.
ayyy gringo its me your hermano
Welcome to having diogenes, I have it and also digital diogenes, which is a little less bad but it makes me spend a big chunk of my money buying HDDs to keep storing data haha
Jeremy Felding had a great video about the centrifugal switch. Really ingenious, old tech
fascinating this motor series videos , have learned alot congrats Mathias
Neat. I had a very similar motor go bad on a washing machine. The nylon sleeve that the centrifugal switch rides on became detached from the rotor and so the start windings would not disengage when the motor spun up.
You are a man after my own heart. I have my own collection of motors, some from over 30 years ago that I salvaged. I just added our old clothes dryer motor to the collection. Motor was good but the dryer was old and it was time for a new one.
Hope to see a project using this motor, I have the exact same motor,. This is very helpful, thanks for sharing.
Made in USA, NICE. Must be a Whirlpool. They made them for Kenmore too, in the past, not now!
Great content , glad you showed up in my feed. Thanks
Nice. I'm the same way, I mounted an old squirrel cage furnace fan on a rolling cart for my dad to use on his patio, works great and has more distance and less spread than a conventional fan.
I made the exact same thing for my dad to use in his shop.
Man, that’s really great content. So informative!!
It's nice to have a stash of motors so you can satisfy your urge to make something whenever the mood hits you. 🙂
0:56 Motor must run for heater to run. 1:41 Tumbler must operate for motor to run for heater to run. Pretty good control sequence.
Great video. Love how you document the reverse engineering. Mahalo for sharing! : )
4:43 It looks like the centre of the pulley may be a 1/2" square from a ratchet extension.
I was just about to say the same thing but figured somebody already has, yes that was what I used when I took my dryer apart.
great... amazing knowledge, good ecology and motoros is also really quiet
Have you ever done a video on making a generator from a motor?
(maybe wind or water?)
That could be a cool project!
In Germany we often say: "Haben" geht vor "brauchen". Means: To have one comes first, to need one comes after that. :-)
I always say that it's better to look at it than to look for it 🙂
I also collect motors, Matthias... But mostly DC motors. 😬
Either way, those are fantastic to build small shop machines!
Stay safe there with your family! 🖖😊
Seems to me that volt-free connection on the motor (two red wires) could be very handy - if you end up using this motor to make a tool, the red wires could be used to control a separate dust collector on a different circuit. Given the fact its designed to handle the power of an inductor - the switching mechanism can probably handle anything you want to throw at it. Another idea that occured to me is if you had some kind of multi-stage dust collection system (using multiple fans), you could daisy-chain them on a single switch with multiple power sources.
My dryer had flat sides on the pulley side for a wrench and a 1/2inch ratchet drive fit perfect on the fan to remove the blower fan
The two blue wires go to the long white long thermal fuse on the blower wheel. Can bypass for this purpose, but never in an actual dryer.
I just got one before yesterday, it took me hours to get it removed from a broke dryer., tested and is working well but I am still not able to unscrew the fan which I like a lot because designed in the way it can serve as a micro turbine if cast fur a durable use.
Great video, good explanation
Wow, that red fan with the thin little centrifugal blades looks funny!
This just makes me think about how much useable stuff is trashed everyday.
The hoarding mantra, "ooh! that's nice... I might be able to use it one day." Ask me how I know...
3:45 oh god that 'insulation' XD
Get some insulated spade connectors, or use shrink tubing on those, nicer estheticaly and safer.
Thank you sir from another collector, WASTE NOT WANT NOT.
So, if I don't waste it, I won't want it?
But I Do want it. So, I should waste it???
That way, I will Still want it????
I'm So Confused!! 😁✌🖖
Isn't that square hole in the fan for putting a half in ratchet in to take it off?
I would love to see you try to make a drum sander. It's a tool I need desperately but can't afford right now and making one has to be cheaper
It must be deeply satisfying to know what you know and be competent to build and innovate.
It could be used as part of a dust collector for a new super pocket screw jig!
My drier uses extra contacts on the centrifugal switch to run the cycle-end buzzer. If the motor is not energized but the centrifugal switch is engaged (indicating the motor is turning) the buzzer sounds. Saved them the cost of a 1-second timer relay. Actually that must have been my previous drier; the current one has not required service yet so I would not know how it is wired.
Infinite Ohms was my college band's name. Now that we are older, our yoga group has the same name.
"I just collect motors when I find them, so that I have one when I need one" - This is soooo me.
The additional safety switch on the blue wire was/is probably the switch in the dryer door to tell it the door is closed.
Got Electroboom vibes when you started the motor with open contacts strown around
It's best to use a flat blade screwdriver to knock the blower off.
I collect motors, and Li Ion batteries, and power supplies of all kinds ... Lots of small DC motors, especially, and, lately, power tool motors, 12 - 18 VDC... Now, to find the time to use them!
For the left-handed thread on the blower side of the shaft you could also use a nut from a spool on a weedeater.
you should have Kept it together and made a mini dust collector
Cuz they look like they're weak but if you make a box for them they amplify their suction power and they can get pretty strong
A very open motor for sure. On a gas dryer with a leak you would go boom when the starting switch opened and made a spark.
He's coming to your town! "The Motor Collector!"
the fastener location on that style of motor was very perplexing for me, as there are no fasteners . whenever i save a motor i also look for a way to take it to bits so i can clean and replace bearings in need be. i got a motor just like that one from an old dryer and its centrifugal clutch was busted so i had to find a way in. so yea, there are no fasteners but a spelter socket type method of assembly.
I do the same thing, you never know how useful the right motor can be.
Save it for a rainy day 😄💕👍
1:48 Door open switch? Could be useful depending on what you are building. E-stop?
great video, interesting. thanks
Love your videos. Have you ever looked at the motors for those coin operated kiddie rides? trying to learn about them now to make my own ride. Thats what landed me here. This video defintely helps me map out some of the raw materials. Thanks
Are you a shop teacher? If yes keep on and bless you sir
Love it! You could use it to blow out hot air in the shop outside. Where is the incoming air ? IDK
I too had an intact take- off motor from a dryer and made a buffer- polisher machine, it works well but gets very hot in a fairly short period. I think the duty cycle rating of those types of motors are short "on" duration, longer "off".
dryers typically run continuously for an hour
@@matthiasrandomstuff2221 Then the answer is obvious; I'm working it too hard. ☺
@@BeachsideHank _How_ hot? It's typical for motors to get hot during normal operation. For example, the motor in my desk fan typically operates at about 65°C on low.
The "nut" inside the blower fan is round and knurled. Short of welding/epoxying it, it's not at all useful. If you come across more of the motors, some have a longer shaft and some have the pully and fan threads reversed. i.e. the fan "nut" has normal threads and the pully has reverse. Just FYI. :)
You know I wonder if a motor like this with the blower in place would be good for a strip sander with integrated dust collection. Sure it’s not all too powerful but I can’t build a blower out of wood so this seems like a reasonable alternative
Merci Matthias !!!!!!!!!!!!!!!!!!!!!!
I collect motors too. I have 3 5-gallon buckets full of them in my attic. Most of them have so many wires they look like a box of Crayolas, so there they'll stay.
Those motors work very well unmodified just as an ventilation fan`. Just hook up a dryer hose and run it to the outside.
It would have really awful efficiency, though. A motor that big could easily run something the size of a condenser fan.
That motor would perfect for a corded minibike the kids could use.
Motors r good to keep when you build tools as a hobby
Very helpful. I just acquired my first motor from my old garage door and haven't started tinkering yet. States 115v, 4.6 amps, 1,000 rpm. Think it's suitable for anything? I'd be interested in building a small bandsaw or small wood lathe.
Suitable for anything that doesn't run for more than 20 seconds at a time. thsoe garage door motors are not continuous duty.
@@matthiasrandomstuff2221 - you should have let him find that out on his own! Rats! 🤔
You are such aCool guy
the red wires are used as a safetly interlock so the heater cant turn if the motor/fan is not turning.
Can you tell me is the number 4 or five spot on the motor the hot wire? The other is neutral correct? And the green wire going to the bent piece of flat copper is the ground?
Cool.
Did you try open Windows at different levels?
I managed to blow air from outside into our house by opening the door to our hot, not sealed attic. My assumption is, that the hot air wants to escape upwards, but cant due to air pressure. When opening the door and a window inside, the air from outside replaces the air that flows out, creating a strong air stream without a single watt of electrical power.
COULDNT YOU TALK ABOUT THE SUPER GLUE YOU SECRETLY COLLECT.
Soon enough we'll probably find Matthias collecting the motor out of his neighbor's car, lol.
Tesla is worried.....
Today I'l show you how to build a 4 cylinder 120HP dustcollector for your average sized basement shop.
@@brucelee3388 Tesla motors need 3 phase power to work.
Well Matthias saving me from doing some research , I have these hoarded for an unknown purpose
thanks!!
is it strong enough to push a blade or router bit
Yep, I have this urge to collect motors too :-)
hoarders r us
@@marks47 LOL, yes :-)
Would you be so kind to let us know what side of the start coiling (circuit ) gets bumped.
Would that motor be strong enough to run a rotor off of each side, and produce more air flow? Not sure how that would be incorporated into a dust collector or whatever, but it seems a waste to not take advantage of it.
One bigger rotor will do better than two small ones
Here's a crazy idea. Make a couple rock tumblers for the kids.
... I was thinking that a pulley and belt to a few levers and you can shake spray paint cans. We all know how we hate to "shake for a full minute" before using them.
1950s American cars still being used daily in CUBA
👍👍👍
I laughed when you plugged it in without holding onto it or clamping it down.
Whenever I have open 120Vac connections, I tape down the wires and think about what might yank on them before I turn on the power. He should have done that.
Sometimes a motor will roll over on the table when you turn it on without something holding it down
@@Malungeon18436571 Not just sometimes! Due to conservation of angular momentum, a sudden start of rotation inevitably produces a perpendicular torque. You see this all the time on BattleBots when robots with high-speed horizontal spinners compete. Every time they make a turn, the torque throws up one or the other of their wheels, making it look like they're dancing. They're not dancing. They're miserable. They're forced to fight day in and day out, getting their guts kicked in. And no robotic sex, either.
@@paulkolodner2445 I’m ok with that. I’m a hardliner on robot rights. Give them an inch and they’ll take a mile.
At last, someone else who collect shit that might come in handy some say! 😂
At least one of those safety shutoffs was for the door open/shut.
weird that there isn't a capacitor for the starter winding, normally the capacitor is used to give the 90 degree phase shift
edit: never mind, it's a split phase induction motor
👍
One can't have too many motors ! ;D
Can I use one of those to do an electric goKart ?
Some people collect coins, some dolls, geniuses collect motors! ☺️
i was trying to make a pottery wheel from a dryer motor, you think thats possible?
Just need to gear it down appropriately. But pottey wheels are usually variable speed and reversible. Dryer motors are not.
Centrifical: halfway between centripetal & centrifugal (at least that is what it sounds like you are saying)
I noticed you have an HP multimeter. I didn't know they made those! Anything the "brand name" does that a no name multimeter off amazon cant?
probably a fluke rebranded. It's nice and precise, can measure AC down to milivolts, and also measures frequency
HP used to make very good measuring instruments. CuriousMarc has a lot of them.
I work on appliances for a living and those blower wheels are incredibly hard to get off at times. Very frustrating
This one looks like a simple square drive would have done the trick.
I’ve never had a issue w it’s the right tools. Socket driver in the blower wheel and and socket on the pulley at the other end. On ones with a speed reducing belt the blower shaft has a flat surface to get a crescent or ring spanner on to. And just remember to turn the right way since they are reverse thread
Never throw away a working motor. Or a power supply.
yikes when you put that wood pry bar in the fan to remove it I cringed.....just last week I had to replace ours and it cost me $170. FYI that centre hub on the blower fits a 3/8 drive ratchet. for removal and reinstall.
"What's in the Box?!?! What's in the Box?!?" Just a couple of motors.
Serious question, what is the difference between DC resistance and AC resistance? Did I miss something somewhere?
yes. Where to begin -- I can't give you an electronics course in a youtube comment.
@@matthiasrandomstuff2221 Okay :) True, you probably couldn't explain it very well in a CZcams comment. I trust you enough...I'll look it up and let you know what I come up with. 👍
Without getting technical and nerdy basically DC uses the entire conductor where AC uses the outer most of the conductor cause the resistance to be higher. Kind of like you had a smaller wire for the AC to travel on.
@@tom5256 That is skin effect and it's not what Matthias is talking about (at 60Hz skin effect is pretty much negligible). The thing with "AC resistance", or impedance as it's properly called, is that inductors (such as a motor's coil) behave as shorts for DC but due to complex reasons actually behave kind of like resistors for AC, in the sense that they limit the current that can travel through
@@gigigigiontis8 Thanks for the info...I'm still reading on it and trying to understand...it's kinda complex, my wife was trying to get me to do something while was reading about it and guess who won that one :)
