Little fun experiment today : we're gonna make spin this fan motor as fast as possible!
Originally, this engine was built on two balls bearing, but we've taken off one of them to reduce the friction. What we have here is a circular magnet, which has 2 north and 2 south poles. We're going to make it spin around this handmade coil, by using a square voltage. We're going to increase the magnet's speed by gradually increasing the frequency. Roughly at first, but very precisely afterwards.
At a low frequency, the coil's impedance is very low, which forces us to limit the current by adding a resistor. We're roughly at 5 amps. Once the frequency gets higher, we'll finally be able to open fire. We'll start with 80 Hertz, which equals to 20 revolutions per second. It's basically the most speed we can generate with our fingers.
Thanks to our system and according to our calculations, we could reach around 100.000 RPM. To give you an idea, it'll spin at one thounound six hundred revolutions per second, which is very impressive. First try ! We're slowly increasing the frequency with our 100k potentiometer.
To increase the rotor's kinetic energy consistently we have to increase the frequency more and more slowly. But when we move consistently the knob of the potentiometer the frequency increases faster and faster. Therefore we need to be very careful and precise while moving the knob to avoid the motor from stalling.
A few stalls, but it's possible to synchronize again at a lower frequency when the rotor is decelerating. At this speed, the standard potentiometer is not precise enough to make sure we're not to abrupt, making it harder to avoid stalls.
It's time to use the precise potentiometer (trimmer) and make a few rotations. From now, the impedance of the coil allows us to take off the resistance (no more current limitation). Now that there's no limitation anymore, we're undoing the revolutions stored in the trimmer to use its accuracy later.
Now that the power is higher (96W, 8A under 12V), we can put the 100K potentiometer on 0 ohm. It all comes down to this moment, with the precise potentiometer. Already 1000 revolutions per second, already hard to believe. As the frequency increases, the voltage is limited by the coil's impedance so motor then consumes less energy : the efficiency is increasing. The speed limit will be reached when the energy provided at every moment will just have to compensate the friction. Imagine the noise it makes, considering the camera is 5 m away from it!
Rotation speed : 1700 revs per second.
Kinetic energy : 740 Joules.
Speed at the edge of the rotor : 800 km/h (500 mph).
Stalling, the deceleration is pretty quick because the system isn't turned off. Free deceleration test from 100.000 RPM
Next step one day… : breaking the sound barrier (1200 km/h) on-the-spot ! - วิทยาศาสตร์และเทคโนโลยี

Amazing, when it started wobbling toward the end i fully expected it to blow to pieces. That's one well balanced rotor. :)
seriously, everything else i've seen spin this fast just instantly flies apart and explodes or just gets off-balance and self-destructs.
@@internetuser8922 If it stayed at full speed it would have started distorting the housing after about 30 seconds or more . A student did a similar experiment at a school I went to many years ago &:the rotor eventually failed .

I find it really hard to comprehend something spinning 1,666 times a second.
Yeah steam turbines spin at 60 times a second.And they weigh hundreds of tons.Imagine a steam turbine spinning that fast.
Nexalian Gamer It would destroy itself before it even reaches that speed
@@Nexalian_Gamer Steam turbines. Now think about Pulsars aka Neutron Stars. The speed of fastest Neutron Star in known universe is 713 rotations per sec.
Just close eyes and imagine a few thousand cats jumping over a fence every second...
If you think that's hard to comprehend, try to wrap your head around 1667 rotations a second.

I can't believe that rotor didn't explode before it got to 100K rpm. The weight of the magnet must have been huge at that speed!😲
Very much the centrifugal forces would be huge. I would not want to be anywhere near that motor in case it failed.
Crazy. The fastest neutron star known to man spins at 716 rotations per second. Not far off from this. So imagine something a billion times bigger,spinning just as fast. Kinda blows your mind
I guessed this thing is 3cm and google says neutron star is 15km so that makes - by size, not mass - a neutron star 500,000 times bigger than this! Which is less than I'd have guessed too. But still that is pretty crazy speed for something that size :/
the staggering thing here is that effective speed on the outermost point increases, the bigger the radius is.
Not to mention the neutron star has the mass of 2 of our suns and it’s 15km across.
Have you seen the BMW overhead cam at 14k rpm video?
@LordGroyper Isnt that 500 quintillion?
What I think is most interesting is that at such an high RPM and no sign of precision balancing, this little motor didn't blow apart was impressive!

Why oh why did I find this so mesmerising? Great work!
I wanted to see someone touch it when it was at max rpm. Reckon your finger would fly off, or it would just get shaven down?
Of course his finger wouldn't fly off. There would simply be a mild abrasion and perhaps a friction burn in the spot making contact.
@@TKing2724 740 joules is enough to heat 1kg of water by 0.18c so to a maybe 5g finger tip that would equate to 36c so a mild burn (not accounting for conduction which depends on how quickly you slowed it down).
@@6Twisted Yeah, like I said, possible mild burn, skin abrasion, but definitely not a missing finger.
Try testing with a piece of plastic if it starts getting shaved so will your finger
the skin would just cut off like a grinder probably but it doesn't have much mass to keep it going, its all horse power no torque.

Awesome to watch!! I was just more concerned that the metal disk/bell cover would disintegrate at that speed. At that speed the centrifugal force is insane...so any small imperfection, in that metal, or imbalance will give a very big problem !! Watch what happens to a simple cd/dvd when spun at only 10k rpm... spectacular !!
Very neat! You reached in 5 minutes what a turbocharger reaches in about a half second.
Turbochargers get alot of rpm with air ... this is by electric motor
This was done for, what, $400, with equipment used for other things. Manufacturers spent many millions to perfect the turbocharger to be able to spin that quickly. Not to mention it uses the mass of something to spin it.

@@nova290r WELL there may be turbos out there that spin to 400k, but I've never heard of one, typical automotive turbos spin from like 60,000 to maybe 120,000 on the high end. 400,000 rpms is so fast.

Do it in vacuum ..you can get more RPMs
Heat would become an issue.

You have way too much drag in water......

your videos are great!
imagine an extremely heavy gyroscope being spun up to these speeds; it would be pretty much impossible to turn it out of orientation.
If you use a idraulic pistons, you probably can, but the earth will rotate making the gyro stay in the position :)
I can't believe it did not blow apart
_____________It was just about to go. You can see it expanding just before the shutdown. There would have major penetration!
Same here. I'm guessing the radius at about 3cm, which at 100k rpm means 335,000g at the circumference. Also a surface speed of about 700 miles per hour.
@@tiafolla This thing is more like 2cm in radius, meaning a peripheral speed of 209 m/s. 304 steel would fail at 251m/s.
It'd be experiencing a stress of about 420MPa, resulting in a circumferential and radial extension of around 0.2%. [Editted; see below]
@Evan Bell
Why different radial versus circumferential expansion? They will of course be the same in %...
@@swhbpocl because the circumference of a circle is 2 Pi times the radius, of course..
I'm amazed that the bearing stood up to that speed for that long. It's too bad that you couldn't design a remote release and mount a well balanced propeller to the metal cup, spin it up as fast as you can then release it and see where it goes. It might be a little hard to see when it gets to the stratosphere though. :) I saw on Myth-busters one time where they took a 120 VAC, 14,000 RPM angle grinder and connected it to 240 VAC. they put a standard CD on the shaft and spun it up with a time lapse camera recording. At first, in time lapse, it was balanced but as it got faster, the plastic CD began to deform in a wave pattern around the circumference just before it exploded.
There was levitation at the max of its speed. Kudos for the effort 👍

When this was supposedly at 100,000 rpm, the frequency spectrum app I have (which I have found to be accurate when reading known signals and in blind tests) had peaks at 800 Hz, 1.6 kHz, 2.4 kHz, and 3.2 kHz. This means the object was rotating at 800 Hz and producing harmonics (multiples of 800 Hz). 800 Hz corresponds to a rotation rate of 48,000 rpm. So, as HL4EHalfLife said in their comment, no way this got anywhere close to 100,000 rpm.
I believe the machine dude is using compared to your raggedy app and a compressed video.

Will relation between diameter and circumference deviate from pi when tangential speed reaches “relativistic” speeds?
@@gabekenyon4882 The G Force would be very high thus the weight will be multiplied (for example if the weight of the fan or motor is 200 Gram and the G force is 100 so the weight will become 200,000 Grams or 200 KG) but the G Force is higher than 100

Love the sound😌
3:20 If removing current limitation increases speed at the same frequency, then it must not be in synchronous mode, therefore all speed calculations are questionable.
Seems to be the wrong place of youtube for reasoning. A mincraft comment gets more attention by 2 orders of magnitude :/
@@procactus9109 that was funny, until I saw the minecraft comment... then it was hilarious. Lol.
measured the sound when it says it reached 100,000rpm. It bounced between 1,6kHz and 1,7kHz. I guess thats pretty accurate.
This how it felt driving my first car on the highway :D
It's better to use a external guage instead of just considering the frequency. I think it may not follow the input frequency, does it?
Wonder if a tachometer would be able to pick this up, would love to see how it compares
Preferrably a digital one
Okay, it's been two years since you uploaded this video, and we're ready to see the next one where it spins at 1200 km/h, and it breaks the sound barrier.
and it's been 3 years since yours at this point i expect to see that little motor break light speed
And it's been 12 months since your post so I expect this motor to be distorting space time by now.
Four years since this comment, I imagine the motor has, by now, realized that earth is flat after all.
Would it not be easier to generate a frequency curve with a microcontroller? Also, is it using an air bearing? If not, it would be interesting to see it run in a vacuum chamber.
Thats awesome never seen a.little electric motor do 1000000+ rpms.

Great!
I subscribed in your channel just now because of this video..
Nice example. But there are vacuum pumps (rurbomolecular) out there wich are running near to 100k rpm with a mass of ~4kg rotating. Normaly they are secured with steel mounts to prevent them from flying away if a crash destroys the rotor. I worked a few times on turbos from Alcatel with a 12 inch diameter and a rotor mass over 15kg. The running speed was 60k rpm.
Current is limited by back emf and impedance. Current can be restored by using a constant current source so the voltage climbs with speed. High speed steppers use a constant current configuration for constant torque.
True :)
Here it's a constant voltage so we have to limit the current by ourselves at the beginning when the back EMF is low. By using 24V instead of 12V it would have possible to go higher in REVs!
True, Since you built your own switcher I figured you would have built your own current regulator to go with it. Many stepper motor drivers include their own PWM current drivers for low heat dissipation and work up to 48 volts to over 100 volts on steppers with less than 5 ohms of resistance.

What’s the external force applied in kg, at 100,000 rpm?
A cool 10,000 g radial acceleration at 800 km/h speed (assuming 3 cm diameter).
you haven't to asume the diameter you have rotations per minute and velocity of the housing.
Could you try this with a larger wheel or faster rotation such that edge of wheel is faster than speed of sound. Just curious to know if there is any special sound effect like sonic boom..

Rotation rate is roughly the same as the fastest neutron star. (42960 rpm)
Note: A typical neutron star is about 20 km wide and has the mass of 1½ Suns. So just imagine what that would look like!
Oh, and the theoretical fastest rate of rotation for a natural black hole is about 323500 rpm for a 3-solar mass black hole spinning nearly at the speed of light. That's almost 5400 Hertz!
