- What can I do with that old Microwave Oven Fan Motor #2. I have had so many comments on my old "What can I do with that old Microwave Oven Fan Motor" video (where I make a version of a Joule Thief using the coil from the motor) that when I was tidying up my junk pile and found another fan motor I felt I had better do something else with it. So I show here that you could use it for a Desk Fan running directly off the household 240 volt AC supply. To do this properly you would need to box it in to make the mains power safe from inquisitive fingers.
***************************
In response to a question I am adding this information
If you flip the stator, so it sticks out the opposite side, the motor will spin in the opposite direction. This is an AC motor, AC = alternating current. So connecting the power wires either way will make it run. The one in this video is running on 240 volts in the UK. USB is DC (Direct current NOT AC) it is also just 5 volts, so you cannot run this fan from a USB port. Please be careful, if your knowledge of electricity is so limited, there is a good chance you are going to electrocute yourself. In the UK that means you will probably kill yourself. The proper name for this motor is a 'shaded-pole motor' and here is a Wikipedia article explaining it's features en.wikipedia.org/wiki/Shaded-...

I don't understand why people are reacting negatively if you're doing whatever you want with your appliances, I'm dismantling them as well and using their parts to create something new and absolutely useful.
Some friends of mine were asking me to sell them those newly upgraded items but I refused, even though they're unique and no one is able to find such powerful ones on the market neither on the internet 😅
Every comment counts as an interaction on the CZcams algorithm, so good or bad, they still help 😁
The fan explains the musical note the microwave oven plays when heating food. This fan spins 45 times per second.
Typically, these kind of motors spin a fan at 2700 rpm, so yeah.
Can't say I have noticed a musical note, just the sound of the fan.
How long can the motor run continuously without breakin?
@@GrandadIsAnOldMan Can I run with a phone charger because 120v to much for me I don’t want to get shocked?
@@MRTOM-gh9pk it is an AC motor, so a DC power supply would not work, even if it was the right voltage.
Hello, thanks for the video. I have a fan from my old microwave oven but it has 3 pins and I couldn't get which pins I should wire. Could you please tell me if you know?
That depends what you want to use it for. The coil has a centre tap. You could measure with a meter to see what resistance the coils are on each side. On my motor the outer tags were the ones the original power wires were connected to. Here is a video where I made use of the centre tap czcams.com/video/7c-AsRsyq34/video.html
Good job man!
Thank you! Cheers!
Excellent demo. I was wondering what kind of AC fan it is. Thank you for that info. It is a great powerful and quiet fan. I have 3 of them too bu it is 120 VAC.
In the UK it will be 220 to 240 VAC
GrandadIsAnOldMan I learned from another video that it is a shaded pole motor. Very interesting operation principle. Thanks again.
@@shvideo1 yes many small AC motors are shaded pole. I believe one reason is to ensure they turn in the direction required. So that makes them ideal for fan motors.
Really nice. :) I'm working on a portable/rechargeable desk fan right now (cutting pipe and plastic box, making holes and so on. And I'm going to use exactly the propeller from a microwave fan... But with a 12v 12500rpm DC motor and a 9g servo to make it turn side to side. :)
Now your project sound much more sensible. Yes, that is a nice fan blade so a handy source and a good repurposing. I only did this video to cover off some comments on the previous one. You have some good looking videos on your channel 😊
GrandadIsAnOldMan Thanks, man! :) Your videos are a great source of inspiration to me. :)
Good simple application. 👍
They also work at 120 vac.
And, yes, the exposed wires & fan blades can be painful 😢.
I find it amazing how many people found this video useful. In effect, all I have done here is taken it out of it's box (the microwave oven) and plugged it back in to the mains. I suppose it is an example of repurposing it, but if I intended to make use of it as a fan, I would have made a new box to put it in. In the previous video (that you commented on), I had complaints from people who said I shouldn't have taken the motor apart, and I should have made use of the fan, so here we are.
@@GrandadIsAnOldMan I find so many microwaves. Destroying them to get materials and seeing all of the bits and pieces is just self education and stress relieving.
@@cptrikester2671 some people leave comments just to try to create a reaction 😊
@@GrandadIsAnOldMan I'm afraid that I am guilty of that on some channels.
Not so much to just get a reaction, but more to present an alternative perspective, and boy does it get a reaction. 🙄
I get the same in return. Fair enough.🙂
Thanks for information
:-)
Wow! No need the capasitor? Directly power from main socket to motor, the motor not hot or burn?
There is no difference between the power connection in the original microwave oven and the way I have connected it. It is an AC motor designed to work on AC power. The big difference is it is not safely sitting inside the microwave housing so this is potentially dangerous as there is nothing to stop you touching the live terminals as I clearly explain in the video.
How many ohms the coil resistance?
I think it can be used as big pulse motor coil or if we can reverse it we can build simple generator that can reach high voltage easily with neodymium magnets.
I am afraid I have no idea. This video was filmed back in 2017. You might find the associated links in the video description interesting.
I'm using mine to cool my DIY "MOT spot-welder", and would love to see your version of a resistance welder, but the risk factors and topic are probably not agreeable to your particular low-voltage viewing audience 😅
Yes, you understand the audience level I am aiming at. Very rare that I do anything with high current or voltage. When I do take things apart with the intention of repurposing them I don't think making a fan from a fan is really a change of purpose. Yes it would be useful but I would not really consider it "repurposing" as it is still doing it's original job. Using it for a hovercraft might be more closer to the content I aim for but an AC motor does not really lend itself to that purpose so my original video on the subject was in line with my channel. This video was just to cover off the comments on that video 😊
GrandadIsAnOldMan what's your other channel?
GrandadIsAnOldMan Yep, I guessed that was the case ☺.
Hi The Tinkerer, here is the link (you will find that sort of information in my video descriptions) czcams.com/users/GrandadsOtherChannel
😊
Hello Grandad. Question are all wall plugs in your home equipped with a switch beside the plug to control the off and on for each half of the plug? Is this a UK building code? I like the idea of being able to turn off certain plugs in each room. Not here in the US. :-p
Hi Ed, I don't think it is a UK building code and you can get them without switches. With many modern devices needing to be powered continuously for things like internet access I would guess a wall switch is becoming less necessary.
GrandadIsAnOldMan Thanks for the info. Save the fan for your shed to vent Styrofoam fumes when hot wire cutting.
Yes that would be an option 😊
I would love to see something like an rc hovercraft. That would be awesome.
Using an AC motor would not be practical for a hovercraft but here are my related playlists.

GrandadIsAnOldMan that's pretty Cool. I didn't realize you already had some out. I guess I didn't look at all. lol
So you plugged a 240 VAC fan motor into the mains and got a ... fan motor - well done.
Exactly 😊 When I took one apart and used the components for another project I got complaints in the comments saying I should have made a fan from it, so this time I made a fan as requested. I explained that in the voice over. It is difficult to please everybody.
Did you look at the associated playlist?
Can I directly connect the fan to mains? (120v 60hz)
Also how can I identifying the polarity of the motor? The wires to the fan is both grey colored. I want to connect a switch to it so I can turn the fan on or off. So I need to identify the Live (L) Wire.
Also, the fan is from a microwave.
First I would say that if you have any concerns you should talk to a qualified electrician rather than trust a CZcams video. You try this at your own risk, I accept no liability. There is no guarantee your fan is identical to the one in this video. Regards the polarity, the one in the video is an AC fan so polarity is irrelevant. If you have taken it out of a microwave you should be able to trace the wiring and see how it was connected originally. I was able to follow the wires from wall plug and trace the route through to the fan to confirm how it was connected.
Grandad, Im your new subscriber, just want to ask, does all microwave fan is ac or dc motor? Can I directly plug it to 220v or 230v line just like you did, Specifically the Hanabishi Microwave ???
I am not a microwave oven expert. I took the oven apart, traced it's circuitry and understood how it worked. The motor even has the details written on it. My advice to all people playing with electronics is that if you don't know what you are doing, ask a qualified electrician. Don't trust "some guy on CZcams" 👍
cute fan!
Thanks Josh, I only did this video to cover off some comments on the previous one 😊
GrandadIsAnOldMan your welcome, the motor it's self on their looks like on the humidifier fan my dad gave to me after we took a broken one apart.
Josh D yeah those AC motors are not uncommon yesterday I disassembled a microwave and it had two of them with fans
i have a fan with 3 holes.i wanted to know which charge is positive and negative
This fan is AC powered so positive and negative is not relevant. If you mean live and return (or neutral), then generally they are colour coded and brown would be live and blue would be neutral.
Hi dear. Did you check how much volt out; iff use for generator.thank you.
No I didn't try using it as a generator.
could several of these be run in series (in a box of sorts...) as a window exhaust fan? thinking.....
I am sure you could, there is nothing special about it and when you look around you can find fans in many items, I was watching a video about cooling racks of processors for bitcoin operations by using car radiator fans.
Thank you muchly! Have done some minimal "breadboard" projects, but I'll have to look into whether I'll need any resistors or anything to make a simple circuit with a switch, a dial, and 4 microwave fans in some kind of case to fit into a window, but shouldn't be too hard. Just gotta make sure don't overload anything...
I think they are pretty low wattage so they shouldn't take much power. The rating is probably written on them but this video is several years old and I don't think I still have the bits laying around to check.
I have the same fan rated 18w can I plug it directly into a 220-240v AC outlet??🙏🙏🙏
I am not a qualified electrician so I would not give you any guidance. I traced the wiring so I could see where it came from and where it went. It was a 240v AC supply and it it went direct to the motor. The watt rating just tells you how much power it will take at the stated voltage. If you are not a qualified electrician then my only advice is that you should seek the guidance of a qualified electrician.
@@GrandadIsAnOldMan yeah sure, thank you so much 🙏👍🥰✌️
Could you do the same thing but plunging it into a car for a car with no a/c. Taking into account building a housing.
Seriously? why would you want to go to the effort of converting an AC fan to run on a low voltage DC power supply. Technically it would be possible but you would be able to buy a 12v DC fan cheaper or even a USB powered one.
@@GrandadIsAnOldMan just curious, I am just getting into repurposing motors and was trying to think of a practical purpose for the fan I have. But I can recognize its easier to just do a/c, thanks.
@@Alistair-gi3bx You may find some of these AC motors are in fact Universal motors that can also run on DC but so far my experience with that type of motor has been very negative.
Universal motors czcams.com/play/PLA5a2xPRSrB1FWx-rsnag03bIWwBmnzt3.html
Love these hot microwave oven conversions but has anyone used the fan motor to drive the sychronous turntable motor to run to the transformer and then to a hairpin circuit with XC transmission and charge btrys that go to an inverter to run the fan motor? Seems like there is the posibility of POTENTIAL.
I am sure there will be a video on CZcams somewhere of somebody doing that to prove overunity but it's not what I am doing here 😊
i have one but is with 3 connnector i guess is + - and ground but what is what only the middle connector is with 2 copper little wire to it so i guess is ground help please im gonna use it for garage and i already make a safe litte box for it that prevent touching the connectors with hands
Sorry, I would not attempt to advise you on your project. When I took this one apart I ensured I could see where the wires came from and where they went so I only reconnected them the way they were originally. Your description worries me as it sounds like you are guessing and that is not a safe way of working with mains electricity. It is very unlikely GROUND is connected to the connector you describe as that would short circuit the live wires. Ground is normally connected to the metal framework to ensure that a fault situation involving live wires touching the framework they are short circuited and the main fuse is blown.
How long till the motor runs without breaking continuously?
Try it and find out!!
Does it matter where you connect positive and negative terminals?
It sounds to me like you have no knowledge of electricity. If you are working on mains power with no knowledge, you are likely to cause yourself harm and maybe serious injury. If you are using AC there is no positive or negative. AC= Alternating current. If you are taking this fan out of a microwave oven, make a note of where the wires are currently connected and trace them through to the fan.
lol that's funny coincidence I just disassembled a microwave yesterday
😊
Hello. So i have 3 questions about connecting mine to the wall like this. First i took the motor apart just the 3 parts you can. Does it matter what way it goes back in? 2 does it matter which of the 2 wires i connect left-right on the motor? And last can i connect it the same way but to usb instead? Thank's in advance 😆
If you flip the stator, so it sticks out the opposite side, the motor will spin in the opposite direction. This is an AC motor, AC = alternating current. So connecting the power wires either way will make it run. The one in this video is running on 240 volts in the UK.

@@GrandadIsAnOldMan okok sound's good. Yeah im not too good at this stuff so before i do something i try to read or like this case ask someone who knows as to be as cautious as i can :) and yeah i wont be touching anything when connected. I have a 2 wire plugg and also i have the right (dont know name) but connections for the wires that goes on to the 2 pins on the motor so i will put then on and tape it before i connect it :) and on mine it say 220 - 240 also. Thank you for the help i appreciate it :)
Please take care 👍
@@GrandadIsAnOldMan it worked perfectly :) So i forgot to ask. About the turntable motor. Can i connect that the same way? ^^
@alexgra4363 As I remember, the turntable motor is not 240 volts. Here is a video where I made use of one czcams.com/video/nJdKdlNKuUQ/video.html
Hey guys, so i am in the process off disassembling my old microwave and i have removed the fan. and it is super greasy and im a total newbie when it comes to electronics parts so i was wondering how to clean it without destroying the coil? It's the first time ever im even touching a coil so i just dont know how fragile they are ^^
You could buy a degreasing spray, or just use hot water and washing up liquid and probably an old toothbrush with a bit of gentle encouragement. Obviously you would need to ensure it was properly dried out before connecting any power to it. You would probably need to oil the bearings before use as degreasing would have removed any lubricant.
@@GrandadIsAnOldMan Ooh ok so if you suggest water i assume that i can just use the 70% Isopropyl Alcohol and spray directly on it? i mean i did see a video before where they recommended not going undet 90% IPA for that kind of cleaning but it would be the same thing as the water then that as long as i make sure its completly dry right? and thank you :)
@@alexgranberg9399 I didn't suggest alcohol. However it is a degreasing agent, so it should get rid of the grease. Take care, as the fumes are obviously flammable.
I have a question that might be a bit stupid but i don't know much about these things : can this motor fail ? (I have a feeling that there there are only fix simple metal part so it cannot fail, am i wrong ?) the fan of my microwave (which is exactly this one) doesn't work anymore (but the oven does) should i just change it ?
It would be very unlikely that the fan motor would fail, there really isn't much stress put on them. I would expect there to be another problem. As I remember it, it is running off the mains supply, maybe via a micro switch that checks the door is closed. There may be more switches involved. You would need to find a circuit diagram or be very careful tracing the wiring. Even with the power disconnected there could be enough power in the big capacitor to do you some damage. A quick look at eBay tells me the fans are available, so you could replace it, but without checking the rest of the wiring you might be wasting your money if the fault is elsewhere. As you can see in my video, I was able to connect the fan direct to the mains supply so I was able to confirm it was working. If you have no electrical experience, I strongly suggest you leave this to a qualified electrician.
@@GrandadIsAnOldMan Lol, thanks a lot for the detailed answer. I know I shouldn't but i have been very careful (I was sober). I connected the fan to the main supply as you did and nothing happenned. Also I switched the oven on in order to test the power supply of the fan and it does deliver the expected 220v. So i believe the engine is dead (just ordered one on aliexpress), it's just that I don't understand what part of this engine could be "broken". Anyway I'll let you know if the engine swap did the trick !
@@arflabrelote1628 I will be interested to hear what the result is.
How do I take the 120 volt and converted into 12-volt DC?
You buy a 120v AC to 12v DC transformer.
Hi. I have 220/230v fan, and i want to ask what materials do I need to have to build it safely?
I would suggest you speak to a qualified electrician , rather than ask some guy on CZcams
@@GrandadIsAnOldMan is it enough to solder the cables to the cable with the socket end? And I have another question because I live in Poland and in Poland there are 230v sockets, can I connect this fan to this electricity in this case if the windmill says "220 / 230v" ???
And is the 220 / 230v range, how many volts can this fan support?
Because I was wondering whether to make a battery from a 9v battery (25 9v batteries = 225v
@@mateuszvogel4301 I am not a qualified electrician so I am NOT giving you safety advice. The fan is an AC fan so it is not going to work with a DC voltage supply. It sounds like you have very limited electrical knowledge so again I say, speak to a qualified electrician. Do not trust advice from people on CZcams.
What CFM does this fan blow?
Sorry, I have no idea. You might find a general answer by searching online for a typical replacement Microwave Oven fan but I don't even remember what brand this one came from so I cannot be specific.
you could try to make a air conditioner out of that with water. I don't remember exactly what was the name for them but they work with water.
I guess you mean a humidifier, a system that adds moisture to the air. Yes you could do something like that. Any fan would work, just arrange for it to blow across some sort of cloth that is hanging in some water. The water rises up the cloth and the fan blows the moisture across the room 😊
and that could be usefull in hot summer days
Haha, I seem to remember we had a hot summer day once 😊
What connector did you use at 1:35?
Those are called spade terminals or spade connectors.
Can this work on 115 volts ac?
I am in the UK, the machine I took this out of would have been rated for 240v AC because that is what our AC is. If you are in a country that uses 115v AC then I would expect that if you took apart a microwave oven built for your country then the fan would be the right voltage for you to use. It will probably have the details on a label on the motor, so I suggest you have a look.
Could I make a sort of windmill out of this by connecting it to a light of some sort or a phone charger?
It is a shaded pole motor and would need modification to make it work. Here is a video by Thomas Kim showing what you would need to do czcams.com/video/yRAtruNgyTk/video.html
I ran the same fan using a 12000 volt neon sign transformer.
That seems a bit excessive. It is designed for normal main electricity. But if it works for you that is fine by me 👍
@@GrandadIsAnOldMan I was making a Tesla coil and happened to have the said fan i just tried for fun and it worked and i thought what else could i power up with a NST.
@@ronaldphillips311 You should have put a video up of the Tesla coil, they are popular on CZcams 😁😁👍
@@GrandadIsAnOldMan i am in the process of building a new one and hope to get 3 foot lightening flashes off it. i will show it when completed. Tesla was my hero.
@@ronaldphillips311 Take care. If you don't already watch this guy, you might find Plasma Channel interesting czcams.com/users/PlasmaChannel
I need to find more.
I used to see them dumped by the side of the road, fly tipping is illegal in the UK, but people still do it.
@@GrandadIsAnOldMan same.
I took the microwave fan out of a microwave. It was easier for me. I have a question. How do I power it? It has 2 wires. Brown and yellow. I have a 2 prong C8 power cord from a computer. Will it work if I put 2 wires on the 2 prong?
I am afraid that if you have no knowledge of electronics, my advice is don't touch it. In the UK the 240v AC will kill you. The motor probably has a label on it telling you what voltage is required. If that matches your voltage, then it should work.
@@GrandadIsAnOldMan ok
looks like a bathroom vent fan
I used for that. 20w it is working pretty well. Even if I have bought mine it would still be 10 times cheaper than a bathroom exhaust fan.
how to turn that into welding plant
I suspect you are referring to the videos of spot welders made using the microwave oven transformers. I feel they are too dangerous and would not feature one in my videos.
Can it be converted into a transformer... jw
You would need to add a second coil so it would take a fair amount of work so probably not worth the effort.
I was jw if it was possible
@@turbo3089 yes and the answer is yes but it would need a fair bit of work 😍
Thanks...
You can make it to a fan
Yes, that is what I said. There is more information in the video description.
all ya did was made an elaborate extension cord !
Yep. This was in response to people's comments on the previous video who thought I should have made a fan out of a fan. Hardly a stretch of the imagination but I try to keep people happy !! 😊
You still didn’t do anything but plugging really??
That's right. Amazing how many people asked me to make a fan from the fan !! Seemed a rather basic step but I try to do what people ask. You may find the video description helpful, or read some of the other comments.
