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 :/
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.
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.
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 !!
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.
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.

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.
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.
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.
3:34 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!

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.
Very nice! But from that point it would take so little effort to make the motor self-starting. If you used two coils, intead of just one, added a CD4017 counter and some diode steering, it would start spinning by itself. I really recommend it! ;)
If you are going to do things like this I fell an obligation to suggest that you purchase a vice or at a MINIMUM a pair of Vice Grips to hold that time machine from setting a course through you, I can vouch that spinning things do fail even when not taken beyond there designed limit! it does happen and it's not a good sight (if your able to see after its done it's damage) yet you take this thing well over and above any design intended for AND you lower it's structural strength and ability to hold balance by removing a Bearing "after my experience" I think your insane to be tempting faith.

I recommend a cheap vise bolted down, I had my C-clamps come loose from the vibration (more than once) running a 15 amp universal motor at 110% voltage. Nearly shat myself when the impeller shattered on the floor.
@DikoMan you may want to recheck your calculations. The surface speed of such an object, even at 100,000 rpm is nowhere near the speed required for (noticeable) relativistic effects.
Holding the motor more firmly may have only slowed it down. a rigid mount would allow for less tolerance in the hubs balancing, and as you can see when this one gets up to speed, it moves quite a bit. if it were clamped in place this movement would have nowhere to go and cause rubbing inside the motor.
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.
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..
We made an prototype fuel pump for a rocket motor that ran at 300k rpm. We had to use all prime number impellers so the harmonics didn't interfere. Winding it up was so damm scary, even thought we had it in a cage. It was incredible small
@@RoJay1983 google vane or blade and prime harmonics and resonate. But in short, and posible oversimplified as this is not my area of expertese, choosing prime is about reducing resonate modes. Vibrations can set up in anything, and you want to avoid resonating with structures that have lots of energy because resonating will cause part fatigue and failure. 4, 6, 8 ,12 vanes naturally have many natural resonate frequency modes. 12 vanes have can potentially resonate in 1,2,3,4,6,12. That is where vibrations in one blade can be transmitted and create vibrations in others. So, a windmill blade will pass in front of its supporting tower. That creates a pressure change that cause vibrations in the blade. If you have 4 blades, it has more resonate frequencies modes than a 3 or 5 blade design. 5 is less efficient and more costly so most wind mill designers use 3 blades. But has 1 and itself to resonate in. Well designed pump vains consider the harmonics created by vane pass frequency with their inlet and outlets. In general the higher the vane count, the lower pressure difference between vanes so a high speed pump may use a larger prime number of vanes. I find it hard to imagine 60 vanes, but that could resonate in multiples of 1 2 3 4 5 6 10 12 15 ect....... 60

@@crazys_tech Thanks
@@crazyforlyrics- how many months
@@crazys_tech I did't notice my mistake ~_~
maybe replace the bearing with a magnetic bearing ?
should have lower resistance and as a result it should go faster
He could put it in a vacuum chamber and that would help as well
@@danielruthenberg8249 probably would burn up in a vaccuum
Why would it burn up???
Wow .... Broo ,
That's just amazing
GREAT SCOTT!!!
Imagine having 2 of these side by side on a hot wheels track
This thing at 100,000 rpm began to sound like a 2001 siren but made with a computer fan screaming it's non-existent lungs out.
This would be much faster in a vacuum, maybe wash off any viscous bearing oil with acetone or alcohol too.
👍👍
The easiest way to go further is to use more power! But the bell is already about to break ^^
You can see it looks like it is about to liquefy.
Vacuum, connect the motor to a copper heat sink and use greaseless zirconia ball bearing.
Next time, get it up to full speed and tip it on its side, see how fast it travels... :p
Dude, I love this kind of content.
Wonder if a tachometer would be able to pick this up, would love to see how it compares
Preferrably a digital one
Imagine having this as a Chassis fan in your pc
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.
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..
Would a ring have a sonic boom?
It would be like 10x louder...
1:46 we're ready to take off.
At 2000 rpm : "I wanna touch it".
At 10000 rpm : "I don't wanna be in the same room as this thing".
5:22
Lol the bug 🤣😂
Bug got disoriented from the high pitch frequencies from the motor..
@@fidelcatsro6948 yep 😊

Legend says Chuck Norris can spin a wind mill faster with his fingers
Legend also says these chuck norris jokes are older than chuck himself.
It’s 2018 I think we can stop now
We made an prototype fuel pump for a rocket motor that ran at 300k rpm. We had to use all prime number impellers so the harmonics didn't interfere. Winding it up was so damm scary, even thought we had it in a cage.
It was incredible small
Interesting thing about the harmonics n prime numbers. Do you have a video about it or more info. Would love to know more
Love to see a video!
.
So you have more info on this project? Would love to see it!
@@RoJay1983 google vane or blade and prime harmonics and resonate. But in short, and posible oversimplified as this is not my area of expertese, choosing prime is about reducing resonate modes. Vibrations can set up in anything, and you want to avoid resonating with structures that have lots of energy because resonating will cause part fatigue and failure. 4, 6, 8 ,12 vanes naturally have many natural resonate frequency modes. 12 vanes have can potentially resonate in 1,2,3,4,6,12. That is where vibrations in one blade can be transmitted and create vibrations in others. So, a windmill blade will pass in front of its supporting tower. That creates a pressure change that cause vibrations in the blade. If you have 4 blades, it has more resonate frequencies modes than a 3 or 5 blade design. 5 is less efficient and more costly so most wind mill designers use 3 blades. But has 1 and itself to resonate in. Well designed pump vains consider the harmonics created by vane pass frequency with their inlet and outlets. In general the higher the vane count, the lower pressure difference between vanes so a high speed pump may use a larger prime number of vanes. I find it hard to imagine 60 vanes, but that could resonate in multiples of 1 2 3 4 5 6 10 12 15 ect....... 60
when youtube recommends u random videos from 4 years ago at 1 am
watching this behind the screen still make it seems dangerous
We want MORE RMP! MORE RMP! MORE, MORE, MORE!!!!
1. What would happen if you touch it? 2. Shouldn't there be some visible warping of space evident? 3. Can you upscale it to the size of a Mini Metro?
