When he stuck that screwdriver into the socket, I knew I'd have to stick around and keep watching!
With two hands and both sides of the circuit exposed, rather dangerous indeed.
Sounds like an air raid siren
Fu Sensei yes
Fu Sensei yeah :D
Yeah
@@whackowafer4765 yes i can do that. I work as a siren installer in united states. I can just put a vacuum cleaner motor on a pole that was remade into a siren! Lol ( i can't do that because a vacuum motor is not a siren)
I was about to write that
Love the test with the meter, very safe
This is the point I realized that this video won't teach me how vacum cleaners works:D I was interested in how sucction works and how to make it efficient.
Thank you for this video. You have exposed the hypocrisy of manufacturers which make products with inferior/unreliable parts while they also claim that they are concerned about the environment which they are filling up with their badly designed products with poor quality parts.
I have a vacuum very similar to this. I had to replace the motor because the brushes/comutator started arcing/sparking really badly. The new motor only cost £12 so pretty cheap. I hope the fan blades don't fail in it. I tested it on DC with my bench PSU at max possible voltage (33+33V in series) and current (3.2A) and it ran much better on DC than AC with no arcing. The new motor does pump out quite a lot of hot air out the back so I only use it for short periods.
The motor runs at 30,000 RPM so it can destroy pretty soon
Jedno video ma o striedavých jednofázových motoroch naučilo viac ako niekoľkohodinová výučba v škole. 👍
Those series wound motors can be quite efficient if constructed properly. They need a soft start for the inrush current, bigger blades, wider air channels and lower rpm. The power consumption could easily be cut down to around 500 W.
Edit: the chip is a 8-Bit microcontroller up to 16 MHz with 2 interrupts, 2 timers, 2 kb ROM, and much more. This µC is perfect for creating phase angle controllers, with or without soft start, even current limiting is possible.
i disagree. that badly designed vacuum cleaners are built only for high rev runs. if you will let it rotate only on 500W it will almost have no suction. i will prefer more heavy vacuum cleaner with 550W induction motor. it is enough. look at the saw dust blowers for small wood workshops. 110mm hose and 1000Pa of sucking power. and it runs only at 2850rpms.
That's basically what I said. Bigger blades (i.e. bigger impeller), lower rpm, wider air channels. An induction motor runs at a fixed speed if you run it from the mains. Otherwise you'd need a VF which makes it expensive. Series wound motors can be controlled quite easily with a Triac and a rather simple circuit. And they are very efficient if designed properly. The now commercially used high-speed motors are very inefficient due to losses in the rotor and the large eddy currents in the stator's steel sheets.
Nice explaination, thanks for the video.
Could it be possible that the excess dust around the motor gets sucked in from the the outside due to non sealed motor compartment? because your filters look fairly clean.
Sir is it posibel to make pump out of that thing I mean that pump ?
What diference betwean tesla pump and other type of pumps?
Im working cinde of some thing similar to turbo pumps but I want purely electric super charger ore turbo.
Because simplicity vise .
I dont use often speed aplication so I need some litel boost some times.
I have an electrolux vacuum cleaner, the motor is exactly the same, the same screws and so on. My problem was that the rubber seal went bad so it wasn't sucking the air properly. The motor itself was fine, no broken fins.
Since you seem to be in the market for a new vacuum, I can recommend the Meile ones, they're quite quiet and good for the money, which isn't that much. I am surprised they don't have some kind of outlet fan to keep the dust out of the machine on the vacuum you took apart.
When you fired the motor and zoomed in on the carbon brushes it looked like it was going to travel though time like in Back to the Future.
Those super-inefficient motors have to have intensive air cooling, so the entire airflow must go through the motor. Thus, all the fine dust must go through the motor. There's probably no other way to build a cheap vacuum cleaner. And anyway, there are always particles small enough to get through all the filters.
@@DiodeGoneWild pokud budeš chtít najít vysavač s motorem, co má vlastní chlazení, tím pádem nasátý bordel neprojde motorem ale jen turbínkou, tak hledej mezi vysavači co pracují s vodou, ty mají motor s vlastním chlazením, takže nasátý prach nikdy neprojde motorem, taky je to pro to, že když nasáváš vodu, tak aby ti vlhký vzduch nešel motorem, nebo když projde pár kapek vody přes pěnový filtr, tak aby ty kapičky nešly skrz motor, taky, když nasáváš vodu, tak motor zvýší otáčky, a průtok vzduchu není tak silný, aby uchladil motor, jen vzniká vakum, který nasává vodu, tak aby byl furt motor chlazenej.
Je to líp vymyšlený, protože když u toho ucpeš hadici, tak motor sice zvýší otáčky, ale ta druhá turbínka ho ještě chladí, a chladí tím pádem ještě víc, když se točí rychleji, když ucpu hadici u normálního vysavače, jak je ta Eta Marrel, tak se motor začne celkem rychle ohřívat... Někdy to zkusím do tý doby, než se z toho začne hulit, až najdu nějakej starej novodobej krám :)
@@DiodeGoneWild No. The dust should get captured in a bag or in a bin (if it’s bagless vacuum). Then there should be a filter. Then there should be a motor.
No dust in the motor unless filter is never cleaned (is saturated with dust). Or not dust in the motor unless it’s a bad design (filter after motor for example).
I'm pretty sure that the wooden block you found sent that flimsy metal impeller to Valhalla.
Ahhh thanks! I didn’t think of that
Hi, thanks for your excellent video!
I want to ask one problem I am facing with my vacuum cleaner (model: Eureka Forbes Trendy Steel Vacuum Cleaner). One day the zip of the dust bag was open and I used the vacuum cleaner in a dusty area and I immediately smelled something wrong. So, I switched off the machine immediately. Then after some days in opened and cleaned the motor of the vacuum cleaner and cleaned all dust and debris. There was no smell of coil getting burnt. I dropped few drops of machine oil on both the bearings. After starting, I could see lots of sparks near the bushes and different smell coming from the machine.
Kindly, suggest the probable problem and its solution.
Either the brushes were worn down or the commutator. You could have tried cleaning the commutator with a polishing compound as well as the gaps in the commutator, or changing the brushes if they are chipped.
you explained well man thx
It sounds like me when I step on a Lego
Very interesting testing with the 18650 batteries!
Now just turn it up a little bit,
*ramps up to absolute Maximum turns* xD
This is precisely why I hate modern vacuum cleaners, cheap, loud, poorly made and just a pain in the arse to fix, not to mention single-stage motors are just too weak to be any good, a decent two-stage motor is essential for a good clean-air vac... :)
Miele uses an 18 bladed single stage motor that spins at lower rpms than shark and dyson. It's one of the only few brands of modern vacuums that are actually good.
I hate modern vacuum cleaners which are really weak. A real vacuum cleaner should have at least 2000watts
Alexandru Vasiliu In the United States portable vacuum cleaners cannot exceed 1500 watts due to national electric code and UL. In North America where I live has 120 volt 60 hertz mains. If you want a really good clean air vacuum, a central vacuum with dual oversized lamb electric motors is mandatory.
Ha, you fools, you all were tricked by the vacuum companies, they trick you into getting a higher power vacuum, but in reality, the motor is just more inefficient to use more power.
@@davidperry4013 stop being Miele shill. You’re stupid if you buy a new vacuum these days that is not bagless.
Tu elektroniku (regulátor) jsem si dal do krabičky, a mam ho na svém vysavači, nebo vrtačce, nebo flexe, co mají jen jednu rychlost. A hodně to využívám!
Beautiful.
Great video.
nice work
superb explanation
Hi bro I want motor top side impler.my vacuum damage in this part
Thank you very much!
The IC is SONiX 8-Bit Micro-Controller SN8P2501B
But why?
Very instructive video! Can you please explain about the blue batteries you used to test the motor (about 9.5 minutes into the video). What are the voltages and I assume they were connected in series? Thanks.
Thank you so much your video helped me
I don't know what this accent is but it's amazing.
Excellent accent! :-D
I have been using a 30 year old vacuum cleaner from eurica fobes(I got the spelling wrong ) and it still works fine!!!
Thanks for showing how to open the motor. I'm replacing the front bearing of the rotor right now. It made a horrible sound.
The small printboard of my hover looks exactly the same, but the IC is programmed by the manufacturer. They are available online, but empty. The working program must be loaded by the manufacturer.
Which one shorts usually or more often, the stator or the rotor windings?
the rotor
Nicely explained.tkq
How long did it work , before it broke ?
Fantastic video! You could give this thing a second life and velcro it to your car roof.
Did you reassemble it
You are a wild man. Your “field test” skills are scary.
What type of motor is it???
Raid siren sound!
Excellent video. It's very comprehensive and informative. You're an excellent troubleshooter and have great knowledge of electronics. Thank you for sharing your knowledge.If I had a kingdom, I would ask you if you'd like to be the minister (or chief engineer if you don't like being a paper-pusher) of quality control of all things electronic :)
The impeller has to physically be as light as possible for the most speed. In this case, the impeller is essentially a soda can but it's well protected or should have been. Matthias Wandel has made a few from wood but they often have trouble starting up and getting up to full speed because of weight so he ends up lightening them.

What I don't understand is how that wood block got in there. I have an Electrolux bagless vacuum and the container for the dust has a physical trap for objects. Well worth the money given all the tiny parts I lose in the carpet.
That wasnt't wood block, that was a rubber cube. I think this used to be a part of the machine, rather than sucked in. It was probably to stop the vibration of the motor, but it got loose. Aluminium is probably a good material for the impeller, but its parts were riveted together very lazily. At 30 000 rpm it just flew apart.
Its not an vacum cleaner its an tornado/nuke/tsunami siren
Good job sir
That is why I will from now on only use genuine dust bags on my new vacuum. These seem to be better in keeping the machine dist free. For example, they have a kind of rubber seal at the entrance to prevent dust from going around the bag.
Danyk, are you sure that's a vacuum cleaner, or is it an air-raid siren? That wooden cube was probably responsible for the destruction of the impeller. Someone ran it without a bag.
Can anyone please explain: the plastic blades that seem to be curved the opposite way to the airflow path.. what are they for?
They channel the airfow and route it under the blades, through the motor. If they were not there, just an empty chamber, then the air would start to rotate with the blades creating a vortex and would not exit (as fast) from the impeller.
So in short, they capture the rotating vortex and make an axial flow out of it.
There are two sets of stator vanes actually. The one which is shown (the damaged), those pass out the flow to the perimenter, then underneath there is another set of vanes that direct the flow back into the center if the motor.
Components in Vacuum cleaner's must be very standardised these days... or maybe just from the same factory in China.
I took apart a broken Vacuum a few months ago and many of the big internal components were IDENTICAL to this one.... especially the motor (even including the same foam wrapped around it's case)
I will check the motor (I kept it of course) tomorrow to see if it is Kingclean Electric Company.... or see if it has a different "manufacturer".
I also gather that these include the most self-serving application imaginable for a thermal fuse: It's not for fire prevention as normal, but just to cut the miserable burning motor off before it's *completely* shorted out, thereby making them "safe" (barely). They're still the most cynical appliance I know by a long way, of course.
My proper *shop* vacuum cleaner doesn't have a thermal fuse, because it doesn't need it (as its efficient motor won't burn itself to a crisp, and a vacuum cleaner is far too noisy anyway to want to leave on unattended.)
I love this guys accent,
I have a very old Electrolux Silverado Deluxe model 1505 (circa 1980-83?). It was my grandparent's vacuum. Over the years my wife has bought and used different vacuum cleaners but we always kept the Electrolux upstairs and used it there. Our newest Dyson just never seemed to clean as well, and now it's broken. So I want to keep my Electrolux in good shape should I take it apart and clean the motor, are there any bearings I can oil?
9:27 got me so good lmaooo
16:11 I want more! I want flamezz! :D
That's a shame as it looked like a neat machine, it didn't last very long :-(.
i Like the purple mains lead lol :-D
That chip has only 4 pins used, can't be much in that chip.
That motor style seems universal, i've seen many different vaccum cleaners, and the motor is always the same shape.
For motors i was taught the center was the armature and the outer is the field coils, rotor and stator is usually applied to alternators.
zx8401ztv it will probably be the TRIAC driver (zero crossing etc), replacing a DIAC and a few other passives most likely. It is essentially a dimmer switch
Haha, seen larger rotors in a hand tool!
Time to put on some gloves and tear apart my vacuum cleaner... it's not feeling well... hopefully just too much dust in its innards.
Is it gaven to you for repair?
I love your English accent .
1:21 its 3 am i am about to go fall asleep and now i am fully awake after this moment.
Can I use vacuum cleaner for high voltage plasma exp??
i just had mine repaired.
symptom: vacuum cleaner doesn't shut off on off position of the potentiometer. and doesn't have an ON/OFF switch.
fix: after testing and many components checks, the potentiometer needed a cleanup on its lowest position that shuts the chopper circuit.
for reference: LG VC6820NRTQY (2000W)
A siren, Sounds like someone just escaped from prison.
nice siren
I always found it incredible the crazy amount of power vacuum cleaners need to suck up dust. Consider this scenario - A builder drilling through concrete with a heavy duty 800 watt hammer drill, plus a 1600 watt vacuum cleaner to collect the dust falling from the hole. Is the vacuum cleaner really doing twice the work of the drill? ;-)
I have exactly the same feeling :). The power is crazy. This is partly because they make the motors too small, cheap and inefficient. The air friction is also quite high in all of those filters and in the entire air path. Finally, the problem is that people choose vac cleaners by power. The more power, the better vac cleaner. So the makers are motivated to make them draw as much power as possible, regardless the suction power. But in the last years, EU starts to regulate this.
for a moment I had four vacuum cleaners
a cheap (18€) 12V dry/wet vac, 180W (no brand)
a cheap (70€) 220V vacuum, 1600W ("Trevi")
an expensive (500€) 220V vacuum, 750W (Dyson DC-03)
a cheap (59€) 220V dry/wet vacuum, 1000 W ("Powertek")
The 18€ vacuum performs the same as the 70€ vacuum, but with much less power (almost a tenth!) and it also can suck up water, the 500€ vacuum performs the same as the 59€ vacuum, but it has better filtration.
Conclusion: I love my 12V vacuum ;D
DiodeGoneWild Old Sloboda vacuum cleaners work only with maximum 1000w and they have better beraings and motor.Bearings and motor generally can last to 30+ years.
@@MrOpenGL Yep, that figures. I myself go with shop vacuum cleaners for *substantial* suction, and hand-held (battery-operated) units for lighter work; each is a vastly better machine than these power-fetish-pandering junkers (which squander as much or more electricity than the former, for about as much suction as the latter).
When you see that a typical fan heater's motor draws
@@DiodeGoneWild Don't forget the leakage. Anyway, 6 years later, vacuum cleaner power has come down and efficiency went up.
How much did that vacuum cleaner cost?
not much, about 50 dollars.
Its construction is exactly like my LG vacuum.
All the cheap vac cleaners are made more or less the same way because there is no other way to build a cheap vac cleaner :).
hi there, DiodeGoneWild!

Where are you from?
U need a vacuum cleaner to clean the vacuum cleaner 😂
How can I get my hand on one of those raid sirens?

How to open motor?? I can't figure out, stuck on this stage from last week. Urgent help needed. Thanks.
good job clouseau
Sounds like a federal signal STH-10 siren

You need a vacuum to clean that vacuum.
Feels like I’m watching Tony Stark invent the Iron Man suit.
This video gave me a nerdgasm🤓
It always confuses me that how Vacuum clear and it's motor prototect itself from intake dust , i could damage it over time if not properly Filtered but even filter isn't enough for long time . So what's the magic tricks
The airflow sequence: the dust should get captured in a bag or bin, then there should be a filter, then there should be the motor/fan.
The motor should not get dusty unless the filter is never cleaned and is saturated with dust, or unless it’s badly designed (the filter is after motor for example which is something I’ve seen).
guys would anyone help me with this.. 10:00 taking the motor´s upper cover off. I´ve seen few videos where they did it the same way. however mine is the other way, the upper cover is inside the main cover´s ring, not outside. I´ve tried to pry it out with a knife (screwdriver wouldn´t fit), than a screwdriver, I´ve tried a bit of a power, light hammering, but I don´t know how much can I push it.
if it helps the piece is Samsung sc15f50ht
(reason is commutator is scratched needs sanding at least hopefully that´ll do)
thanks. nice video, quite funny however lots of useful info
No schematic this time?
you could fix the motor by finding a new fan and plastic assembly if you have them , but being able to buy these for under 14£ on ebay its easier just to buy a brand new motor
0:08 sounds like an air raid siren
I didnt know you can run 2- 18650 batteries (6v) in series to make the motor run.
8.4 volts if fully charged. Made it turn a little bit.
4:29 I thought he was going to smash the machine XD
Looks like (except my comment/reply) you are completely alone! You literally got absolutely no replies OR likes in A WHOLE YEAR!
You need a vacuum cleaner to vacuum clean the vacuum cleaner during repair -;)
Something was wrong with my mum's 13y old one it was turning off itsself but my father fixed it
I thought it was air raid siren xD
Jakej smysl má ten vysavač s univerzálním motorem,když triak odepne pouze v průchodu nulou při sinusovce.Nejspíš kvůli výkonu motoru,chtěl bych vidět ten klasickej motor a takovýma parametrama :D
Jasně že ten vysavač je jen na střídavý napětí. Jenže s indukčním motorem by tam musely bejt převody na rychlo a ještě by ten motor byl větší než celej vysavač. Tenhle motůrek je více méně přímotop, ale zase je malej, levnej a ten vysavač uzvedne i drobná uklízečka. A ostatně, všechen příkon vysavače se postupně změní na teplo. Něco rovnou ztrátama ve vinutí, a ten zbytek vzdušným třením.
"Skrjeeew!" Hilarious! :D What kind of accent? Can't figure it out. :)
Prosím udělal by jste to video i v češtině nebo s titulkama sbíram a opravují vysavače a tak by jsem se rád něco priucil
Electronics from vacuum cleaner could be re used as light bulb dimmer.
If I make a working suction motor, it would be an efficient 700 watt 2 stage switched reluctance motor that sounds like an late 1980s through 1990s vacuum cleaner motor and be very very powerful.
why universal motor doesn't need run capacitor like the induction motor??
thanks for your response
No.
It is because the universal notor is kind of dc motor but the ac motor requires a capacitor to shuft the current forwards.
@@tusharkabir2970 What about the small suppression capacitor across the main input? I’ve seen that in a couple of devices. Are those motors universal DC motors?
