Yes, I'm still waiting for the 6th part of the SMPS tutorial. I don't blame him though, the projects are ambitious and his situation has been quite limiting for many years now with the house he lived in being in poor shape and the move to Cologne.
Really looking forward to TPAI building a Universal (washing machine) motor speed controller using a TDA1085C. I'll even buy him the chip, and any other bits, if he'll make the circuit!
Dude, torque is related with wattage and rpm (increase wattage or decrease rpm and you have higher torque) T = P(hp)*63025/n where T = torque (in lbf) P(hp) = horsepower delivered by the electric motor (hp)(1hp = 750W) n = revolution per minute (rpm)
Jeronimo Murruni Are the quoted wattage figures a function of power used or power output? If it's the former then your calculations/formulae will need to be redone.
You may want to add 3rd brace to the backside of that motor. Under high thrust, the mounts may torque and allow the propeller blades to touch the duct walls.
I would use this fan for venting dust from my small woodworking shop. I have a vent to the outside, above the door and would use this to exchange the dusty air for clean air brought from the opposite side of the building. This would be in addition of my existing dust collection system within the shop.
jason Inlaws use one to suck outside air in and through the whole house at dusk and it is magnificent...The movement of cool fresh air comming in from the windows soothes a person after a hot day
Wenn der Trailer schon spannend ist kann das Projekt ja nur besser werden! Man könnte ja eine Klimaanlage oder einen Luftfilter für Staub in der Werkstatt bauen. Ein Heizlüfter wäre natürlich auch sicherlich machbar. Super Videos übrigen ;)
I would have placed carriage bolt heads inside the duct to aid in promoting laminar airflow inside the duct itself. Then again, I'm just sitting here behind a keyboard and you're actually making things :D Keep up the excellent work and inspring videos, sir!
I think someone already mentioned this, but I think you could use this to extract smoke while welding or extract fumes when you use any chemicals such as Brake Cleaner, Engine Degreaser, or other toxic chemicals. You could also use this if you ever decide to make a forge.
Build a wind tunnel. I've build one as a child a little bit smaller to test my Lego cars. :-) Use Drinking-straws to get rid of turbulences from the propeller. You can highlight stripes of fog with a fast rotating mirror and a laser LED. You can "slow down" the moving fog with a strobe light. I found it extremely fascinating watching the fog move and testing airfoils and drag. I even build a scaled model of our house and tested it in the wind tunnel.
You can get less noise if you put some padding on the ducting, also, if you add some trailing "wedges" on the tips of the blades, check how they shape helicopter blades.
How about constructing a small snow cannon, like the ones used in ski resorts? If I'm not mistaken, all that is needed is to spray water in a fine mist in front of the propeller, and it will cool the water with evaporative cooling, and thus make snow. It should work at temperatures up to 6C*, depending on the humidity.
Ah, the aerodynamics experiments station. Let us see how does it handle things like narrow intake/outtake, variety of airflow and possibly temperature as well. Last week I almost scored a motor like that but a random dude with a hammer appeared in the middle of the night at our dumpster and took it out of the abandoned washing machine while I was fixing the electrical system of my woman's car, I felt so powerless!
Telos954x yeah you need a heat source as heated air carries more humidity than cold air, and you want it to get the water put of what you are drying. The higher the ambient temp and humidity the higher the temp of your dryer should be.
You could reduce the diameter of the motor shaft by filing it with a metal file while it's spinning. I have done this many times and it worked very well. This way you wouldn't have to worry about weakening the propeller by enlarging the hole. I hope thi helps in the future. Thanks for all the great videos!
What you could do: Mount it to your window in summer time. Or maybe as a compressor? (Add a funel on the output side...) Does it need 220V AC or 12V DC?
Make a vacuum cleaner! I have a large attic with years of dust and would like to vac it out before I insulate. I have a commercial kitchen fume hood that I would like to reduce the opening to where I would attach a 100 foot vacuum hose. I would run the dusty discharge into an evaporative cooler so the wet pads will catch the dust.
a scaled down swamp boat is what i am thinking. use a couple of these with variable speed controllers for directional stability and thrust efficiency ;->
I have one of these specific induction motors, also trying to find a useful application. The other day I came across one of these plastic eight-bladed fans, used to cool car radiators, driven by a 12V motor. These multi-blade affairs often have a "safety ring" at the circumference(like this one) to alleviate the dangerous aspects. The particular one I have, measures only 360mm, but I'm sure there are larger examples available.
Could make a nice windtunnel. I personally would use something like that in conjunction with a good (Highspeed)camera to make visuals of the effects of different types of arrow fletchings.
Those motors are normally rated for around 500w, a smaller BLDC RC motor could produce more power. Also I am curious what speed the motor is running at max power as it would normally be spinning at around 20000RPM, so the temperature, current and efficiency would be interesting to know. :-)
Any kind of venting/circulation of air in a residence, workspace, or underground setting. A four blade prop running at low speeds would move a lot of air. Same four blades at high speeds and you have a wind storm!
An inline duct fan for an industrial building. A whole house exhaust fan, similar to an attic fan, which could be fitted to a window. An exhaust fan for a workshop, possibly with a barometric damper, to exhaust welding or paint fumes. Initial inflation of a hot air balloon. Mount it horizontally, a few feet away from a vertical axle, and see how fast it can go around in circles. (I'm certain you can solve the electrical connection for the last one.)
It would be fun to figure out a way to measure the pressure and do some experimenting demonstrating the Venturi Effect. You could also use it to vent a bomb shelter.
Perhaps experiment with varied coned intakes and restricted discharges to find out which combo lowers the ambient air the best, and doing so with the best motor efficientcy? A freon and compressor free ac unit
nice build, but really isn't a ducted fan. just fan in a tube. if you changed the propeller and tightened the tolerances of the tube to within 1mm of the propeller tip, then you might have a ducted fan...still there are other aspects to consider...fir example mounting the motor outside the duct and using either belt or chain to power centrally mounted propeller. This would reduce the turbulence and restriction on air flow through the duct. Since you using such a high power motor as compared with hobby motors might consider using a 4 blade prop or extending the shaft and adding second prop rotated 90 degrees on the axis...
Out ou curiosity where is the "vaccum" side of the propeler? towards the motor o away from ir? An interisting feature you can implement is to make sure the propeler pushed agsint the motor that way, if you pin fails (for whatever reason) there would be no grave damage. Besides that, great project.
you need to put a rounded intake lip on that.. and potentially restrict the exhaust diameter dependent on what you plan on using it for... but the intake lip is a must
Ollyweg 0 Air, like most fluids, doesn't like to make sharp turns. There are pieces of software out there that will calculate the optimal lip radius for you. In testing of my small electric ducted fans I've seen improvements to thrust of about 10% with just the addition of a front intake lip. I'm not sure what the gains would be here due to the larger size but I'm sure that there will be gains. cheers!
Dear friend. Make it all in one, portable ventilation unit. Bigger battery, four caster wheels, hinged access panel, a switch, and a charge port. Plywood and metal, including adhesives. With a full compliment instrument array obviously.
Get a light weight car/go cart, seal the bottom and use a few of these to increase down force. Like ground effect but standing still. Suction increases with surface area, becomes very efficient. Get 2+g standing starts and 3g corners. Has only been done once before in F1 and once in a road racing car. Suspension needs to be very stiff but you could get around that with some engineering prowess or just a suspension seat. Use ecu water cooling blocks to cool the brakes on the cheap.
My first thought was dust collection. The question is;: Will this propeller produce high pressure, or will the moved volume drop drastically if you confine the moved air in a smallish (120mm diameter) tube?
you may use it for checking the "holes" in a, lets say bulding, by producing an overpressure in the target and use some kind of smoke... ...or you may use it (with some additional machanics to make the ariflow more linear) for a windtunnel... ...or you may use it as a powervent to get rid of chemical or exhaust gases... ...you may also build a extreme powerfull cooling system with some "old" heatsinks... ...or use it as testequipment for windturbines ...or use it as base for a snowmachine ...or use it as basis for a powerfull gas-heater ...or for drying some stuff ... ... ;-)
Question: Do you feel that if you would have made the shape of the duct/nacelle more like a venturi, the air would accelerate, after having passed the narrow section of the venturi form?
I like your videos more than Great Scotts. He makes incredibly short videos with explanation, but everything is so fast and brief that I can't follow most of this. Like in this teaser. And that's it! No detailed build and detailed explanation and the videos are even divided in multiple 5 minute parts. That's why I find your videos much better and well made! Keep up the great work! Greetings from the Ruhrpott!
Die Propellerblätter sind nicht auf den Betrieb im Rohr ausgelegt, daher wird das nur mäßig etwas bringen. Um das Rohr wirklich zu nutzen, müssten die so aussehen wie die Blätter von PC-Lüftern ;)
Hi. Can you add smaller metal propeller blades ,and when motor is running on high speed , apply water stream at 90 degrees to propeller blades. It should lift motor, that means new flying technology. Let me know.
Maybe convert your energy source to solar? The speeds would be much slower, so the design could be opened up or built with materials that allow better visuals. Your lines, attention to detail, and overall look is already quite artistic. Pretty sure it would make a hell of a conversation piece! Nice work and great video about building and repurposing something just for the challenge, then trying to find a use for it. I get asked "why are you doing this or that" all the time. I usually just say "for the challenge".
looks good TPAI! may I ask what is happening with the EDM and what kind of frequency's it's capable of? a few simple ideas taken from your video library on RUclips, the possibility of an ion jet or EDF\ion thruster hybrid may be possible!? The EDF\EDM ion Jet engine!?
Finally something that would be able to cool down my CPU.
FX 9590?!
Use the fan as a fume hood for welding and similar stuff!
I'd totally need one this size for myself... my farts don't even go away when I'm outside
Just imagine how they are inside
@@audiocrush They must be pretty damn gnarly!
do we finally get a conclusion to the project of the washing machine motor controller? :P
really?
Yes, I'm still waiting for the 6th part of the SMPS tutorial. I don't blame him though, the projects are ambitious and his situation has been quite limiting for many years now with the house he lived in being in poor shape and the move to Cologne.
Really looking forward to TPAI building a Universal (washing machine) motor speed controller using a TDA1085C. I'll even buy him the chip, and any other bits, if he'll make the circuit!
His SMPS tutorials are much better than the very very short one of Great Scott. Also can't wait for a conclusion part. :)
come on guys, do you really expect the guy to finish in 2 days
just sit back, relax and trust tpai
you should try a hover craft!!!
its massive, heavy, and only 500 watts! TINY rc aircraft models in modern day are as much as 1 Kw and theyre the size of a strawberry
Yep, but it has TORQUE
Dude, torque is related with wattage and rpm (increase wattage or decrease rpm and you have higher torque)
T = P(hp)*63025/n
where
T = torque (in lbf)
P(hp) = horsepower delivered by the electric motor (hp)(1hp = 750W)
n = revolution per minute (rpm)
If a motor has high wattage output, then you can have high torque as well
Jeronimo Murruni Are the quoted wattage figures a function of power used or power output? If it's the former then your calculations/formulae will need to be redone.
You could use it as a small wind tunnel or to cool down a car when dyno testing for power this was a brushed DC motor?
It's a brushed universal motor, works on AC or DC
You may want to add 3rd brace to the backside of that motor. Under high thrust, the mounts may torque and allow the propeller blades to touch the duct walls.
What music are you playing?-I really like it!
I would use this fan for venting dust from my small woodworking shop. I have a vent to the outside, above the door and would use this to exchange the dusty air for clean air brought from the opposite side of the building. This would be in addition of my existing dust collection system within the shop.
This would be a great shop fan/extractor. Cheap and efficient. Just throwing that idea out there.
I was thinking that would make a great attic vent, or whole house fan
jason Inlaws use one to suck outside air in and through the whole house at dusk and it is magnificent...The movement of cool fresh air comming in from the windows soothes a person after a hot day
Wenn der Trailer schon spannend ist kann das Projekt ja nur besser werden! Man könnte ja eine Klimaanlage oder einen Luftfilter für Staub in der Werkstatt bauen. Ein Heizlüfter wäre natürlich auch sicherlich machbar.
Super Videos übrigen ;)
It's a thing of beauty. Looking forward to seeing this concept develop...
Addition of high pressure fluid pump, a little hole, a petroleum derivative liquid of your choice and a spark would be most entertaining.
I would have placed carriage bolt heads inside the duct to aid in promoting laminar airflow inside the duct itself. Then again, I'm just sitting here behind a keyboard and you're actually making things :D Keep up the excellent work and inspring videos, sir!
you're making a wind tunnel...right? 😁👍🏻
I think someone already mentioned this, but I think you could use this to extract smoke while welding or extract fumes when you use any chemicals such as Brake Cleaner, Engine Degreaser, or other toxic chemicals. You could also use this if you ever decide to make a forge.
Dang, a fair bit of work involved, but a nice ducted fan to show for it!
Now you can make a wind-tunnel for a VR racing simulation!
Build a wind tunnel.
I've build one as a child a little bit smaller to test my Lego cars. :-)
Use Drinking-straws to get rid of turbulences from the propeller.
You can highlight stripes of fog with a fast rotating mirror and a laser LED.
You can "slow down" the moving fog with a strobe light.
I found it extremely fascinating watching the fog move and testing airfoils and drag.
I even build a scaled model of our house and tested it in the wind tunnel.
You can get less noise if you put some padding on the ducting, also, if you add some trailing "wedges" on the tips of the blades, check how they shape helicopter blades.
I was thinking the fan for a hovver craft, no water required.
Pop a large heating element inside, the largest hair dryer ever made lol :-D
How about constructing a small snow cannon, like the ones used in ski resorts? If I'm not mistaken, all that is needed is to spray water in a fine mist in front of the propeller, and it will cool the water with evaporative cooling, and thus make snow.

Pair it with a heat source for the biggest DIY food dehydrater you'll ever use? Jerky and dried fruit for daaaays
Better with a cooling source because summers in Germany are really nasty. :D
***** I'm from Florida, I know all about nasty summers. But, if you're dehydrating meat and fruit for jerky, you need a heat source in it.
Telos954x yeah you need a heat source as heated air carries more humidity than cold air, and you want it to get the water put of what you are drying. The higher the ambient temp and humidity the higher the temp of your dryer should be.
Would make an amazing dust collector for the shop if you got the bags for one.
You may need to upgrade all those connectors on the motor to automotive sealed units. That duct looks awesome!
You could reduce the diameter of the motor shaft by filing it with a metal file while it's spinning. I have done this many times and it worked very well. This way you wouldn't have to worry about weakening the propeller by enlarging the hole. I hope thi helps in the future. Thanks for all the great videos!
i like his way of thinking :D First he makes something and only then figures out what to do with it
Thanks.
Can be used (with some streamlining) as suction fan/blower in wind tunnel testing.
Wind tunnel apparatus - very similar to the one built and used by the Wright Brothers for testing aerodynamics.
For inflating bouncy castles , And if you narrow the gaps between the prop and housing you would have much more thrust .
I was watching the shroud building process and thinking TPAI should have built it first and then trimmed the propeller to suit.
James Lamb He would have no way to balance the prop and it would of self destructed .
Please do efficiency (thrust per power) measurements with and without the duct!!!
great video. I like the sound of the propeller.
What you could do: Mount it to your window in summer time. Or maybe as a compressor? (Add a funel on the output side...)
Does it need 220V AC or 12V DC?
It's a brushed universal motor, works on AC or DC
wulf 659 But which voltage? 220V on a ship on water is maybe not a good idea.
Fantastic idea! Love the build!

Making a wind tunnel would be cool.
Need this for my home made snowmaker.
You can dry your laundry with it :)
You could use it on an air boat and add some rudders to deflect the air and steer the boat.
Have you measured the thrust you are producing? It may be significant.
a oversized fume extractor or under size depending on how much you use solder
I once manage to grind pinion like that with an angle grinder so precise that there was not any marks left on motor shaft.
I have one of these specific induction motors, also trying to find a useful application.

Looks like it'd be a pretty good PPV fan.
You should hawe a TV show when building things!
You are popular among the kids to.
With a heating element you could potentially heat a room although the airflow is probably to fast and loud
Out ou curiosity where is the "vaccum" side of the propeler? towards the motor o away from ir?
An interisting feature you can implement is to make sure the propeler pushed agsint the motor that way, if you pin fails (for whatever reason) there would be no grave damage.
Besides that, great project.

paint booth extractor fan or welding fume extractor.
how about using an impeller instead
what is the purpose of ducting other than blowing the wind directionally and protecting against accidents?
None. But those are two very useful features.
Ducted fans are more aerodynamically efficient for the same diameter propeller
My fav German. Always with great experiments.
Great video dude !!
Make 3 more...
Build a quad.
Dear friend. Make it all in one, portable ventilation unit. Bigger battery, four caster wheels, hinged access panel, a switch, and a charge port. Plywood and metal, including adhesives. With a full compliment instrument array obviously.

Hello, I can't see vibrations on video but I guess the way you fixed the propeller will make the system shake a bit...
You may use like industrial hot air blower. :)
Great job. Look good and works good. I tip my hat to You.
My first thought was dust collection. The question is;: Will this propeller produce high pressure, or will the moved volume drop drastically if you confine the moved air in a smallish (120mm diameter) tube?
flare out the front into a bell mouth for even more air intake and taper the rear of the duct. More thrust more fun
Make a goddamn airplane with these in the next video.
We need a freaking airplane
Hypergen 8
too heavy components for the power...
Kühn its a joke
dangerously brilliant.....
good video love your videos
Schoen! i love the editing.
That looks good, maybe a car radiator fan would be more robust?
you may use it for checking the "holes" in a, lets say bulding, by producing an overpressure in the target and use some kind of smoke...
...or you may use it (with some additional machanics to make the ariflow more linear) for a windtunnel...
...or you may use it as a powervent to get rid of chemical or exhaust gases...
...you may also build a extreme powerfull cooling system with some "old" heatsinks...
...or use it as testequipment for windturbines
...or use it as base for a snowmachine
...or use it as basis for a powerfull gas-heater
...or for drying some stuff
... ... ;-)
Powering it seems to be the biggest issue. Still and interesting build.
Do you think that this washing machine motor can be used to power an ultralight aircraft, maybe using a hang glider wing and a trike configuration.
>> A wind tunnel
Question: Do you feel that if you would have made the shape of the duct/nacelle more like a venturi, the air would accelerate, after having passed the narrow section of the venturi form?

Greetings from the Ruhrpott!
won't hurt the local wildlife a bit. a few minutes of noise won't do any damage at all. they'll come back right after you leave.
RC plane, make it happen PLEASE.
I have wanted to make that with a washing machine motor for ages. :D
Die Propellerblätter sind nicht auf den Betrieb im Rohr ausgelegt, daher wird das nur mäßig etwas bringen. Um das Rohr wirklich zu nutzen, müssten die so aussehen wie die Blätter von PC-Lüftern ;)
Never mind. Hab das Video nicht bis zum Ende angesehen. ^^
I like the style of the video 👍
That's a very powerful hair dryer you got here ! xD
Jokes apart, you could try to put that on a rolling board maybe ?
Can you calculate the flow rate (cubic Metres of air per minure) and the voltage and current requirements for the motor.
Hello, can you detail the electrical connection of the washing machine motor to 220 volt.
Thank you
Hi. Can you add smaller metal propeller blades ,and when motor is running on high speed , apply water stream at 90 degrees to propeller blades. It should lift motor, that means new flying technology. Let me know.
Maybe convert your energy source to solar? The speeds would be much slower, so the design could be opened up or built with materials that allow better visuals. Your lines, attention to detail, and overall look is already quite artistic. Pretty sure it would make a hell of a conversation piece!
Nice work and great video about building and repurposing something just for the challenge, then trying to find a use for it.
I get asked "why are you doing this or that" all the time. I usually just say "for the challenge".
Work shop extraction fan?
What kind of amp-draw are you seeing? Is that propeller loading the motor at all?
Workshop fan exhaust ? Wind tunnel with lamination turbulence straighteners (straws)
you can put a big flower on the end of the dock and it'll increase power
William Richmond what do you mean by this? do you mean one of those big thick propellors?
Perhaps you could have used an old washing machine drum as the shroud ?
U can make a huge rc plane with that. I guess! Is the motor powerful enough??
Wind tunnel to test the aerodynamic properties of objects.
looks good TPAI! may I ask what is happening with the EDM and what kind of frequency's it's capable of? a few simple ideas taken from your video library on RUclips, the possibility of an ion jet or EDF\ion thruster hybrid may be possible!? The EDF\EDM ion Jet engine!?
Really nice tiny ventilation you got there. :v LOL Just kidding, really great! Well done!
