Overvolting DC-Motors. Vacuum, LN2, Butane and more of your suggestions! How fast will it spin?

[@Cskirt]

Thank you for watching! Thanks to you I can buy all this exciting equipment! However, this episode was very expensive to make and it probably won't be profitable for a long time. If you have any suggestions for other videos involving liquid nitrogen or a vacuum chamber please let me know! Or any other video ideas you have, I love testing your suggestions! This experiment would probably give more interesting results by overloading the motors instead, do any of you have an idea of some kind of variable load that's easy to mount and provides useful data? Sorry for some bad flickering on the multimeter, apparently my 2nd camera decided to change its shutter speed... If you'd like to support my channel more you can do so on Ko-fi ko-fi.com/cskirt or super thanks, I've been thinking about starting members and/or Patreon but I'm not sure what to offer there, suggestions?

[@embersales6031]

Please do overvolting tv part 🙏

[@crazyfurnaceguy1229]

Motros in LN2 are too cold that make sleeve bearing shrink and chroke the rotor shaft , want improve this problem, you need to enlarge the hole of the sleeve bearing, especially the metal part.

[@toma.3d]

For adjustable mechanical load that can handle a lot of power = bike disk brake, wired ones, not the oil driven ones, so you can use a screw to tighten slowly.

[@jordananderson8299]

The egg whites had to be the funniest one yet

[@electrothecat07]

The egg got cooked lol

[@rxmclaren7]

I think the issue with the motors in LN2 is that they have a lithium based lubricant on the gears and some of the other moving parts...if you can figure out how to remove the grease, maybe soaking in acetone or an ultrasonic cleaner, I think that might help with the lock up the motors are experiencing... just a thought...

[@mineyoucraftube1768]

afaik there's a brass disk acting as a bearing for the shaft, i think widening it should help

[@TankR]

They're just brushed DC motors, no gears or nothin, just some finger brushes to a 3 coil commutator and a pair of magnets. Sure, grease could be part of the lower RPM problem, but the big worry is thermal contraction. The casing will get shorter along the shaft pinching it front to back, some motors have a very thin gap between the armature and the magnets (whos field will condense, getting smaller but not losing overall strength, ergo the field flux density will go through the roof) so it could bind up there as the thing contracts around the diameter, as the other commenter mentioned the front bearing (actually more like a bushing, these things usually dont even have proper bearings in them, especially not the cheap ones) could contract around the shaft seizing the works. The problem here, is shaft squeezing. 😉

[@TheOfficialDorianelevator]

in case you overvolt more objects, i got a idea, you could try overvolting one of these 220V MS-190 sirens (they cost little to nothing), knowing they use AC brushed motors, it probably will get very very funny.

[@Cskirt]

Thanks, I ordered one :)

[@ATK_J.Y.S_I.N.D_Offical]

Cool experiment! :3

[@Euklides_Diophant]

Intersting with the nitrogen, thought it would be much better than it did as a knee jerk reaction, but now when I see it I can only think they are seizing due to incompatable material shrinkage, would explain the massive load on the screwdriver motor and shrill noise as the axel probably got pinched by something.

[@Cskirt]

Yeah you're probably right.. I'll also try a series wound motor next time i refill my nitrogen to see if it works better. I have a few ideas that might make it worth a refill soon, but if you have any suggestions that could be interesting, let me know :)

[@Euklides_Diophant]

@@Cskirt One thing I think could probably help is to let the temp normalize when using liquid nitrogen, or else the exterior will get really cold and shrink a lot more than the interior that is warm. maybe putting it in a container with desiccants before to pull out moisture so that moisture doesn't freeze all around it as prep? As for the other tests you were doing, the whipping up a mess with the mineral oil probably mess with the results a bit, I'd fill it up more and let it sit in vacuume to pull the air bubbles out of the windings. They end up expanding when heated and cause those small bursts and pops that then let it draw in more air. (since your setup isn't a high vacuume one) Maybe a low viscosity oil if there is such a thing? Would help the oil get deeper into the motor.

[@Ole_CornPop]

​@Cskirt a brushless motor with ceramic bearings would be the best bet.

[@Ole_CornPop]

​@@Cskirt.

[@rchltmedia]

4:46 AY YO? WHAT? losing over this 😂

[@Unrecognizable.metamorphasis]

@CSkirt Please read a little about propylene glycol if unfamiliar. I believe using PG that has been warmed up a bit for the sake of viscosity reduction, could be a good option as it's not conductive, and won't hold bubbles so much.

[@jacquesb5248]

interesting results

[@pierrelaboom4026]

I have done fun things with 2 variacs..double stacked on cordless drills ect..340 dc volts is exciting. Im newest sub!!😅😅😅

[@CjJackon]

Screaming for mercy😂 12:27 13:29 15:05

[@un2mensch]

So I guess to have a successful LN2 experiment, you'll need different bearings. My guess is the front bearing (usually a steel ball bearing) has lubricant which freezes solid. It would make sense to find an un-lubricated advanced ceramics bearing, as long as you allow more time to cool down the motor. Despite having very low CTE, those advanced ceramics bearings don't enjoy thermal shock and could shatter before you even reach your target temperature. The rear bearing is normally a journal bearing (in most smaller brushed DC motors anyway), which is probably OK at cryogenic temperatures, as long as the same alloy was used for both the shaft and the outer race. Or at least made of alloys with closely matched thermal expansion coefficients.

[@putz460prints]

what kind power supply

[@binarbakhtyar6226]

14:25 this time put the power supply in LN2 maybe prevent shutting down 😁

[@novaldipadmadisyiffa3022]

good video, I like it, do more experiments like this, if you don't mind, try soaking the electric motor in a fairly thick liquid, it's up to you whatever the liquid is, if possible, of course with overvoltage😃😁

[@Dahmainman]

Cant you tell rpm by sound?

[@minidawnplayz]

13:14 a bit of dubstep plus some yodeling

[@topduk]

These motors usually just have a bushing, but the LN2 will shrink the outside and hold the shaft preventing it from turning. Replace the bushing with graphite and it might work.

[@IrishSpyHD60]

Mineral oil without the vacuum could be promising. Given you will need some sort of pump and an oil cooler with a fan in order to keep the oil temp from getting too hot.

[@electrothecat07]

Items in a vacuum make no noise since sound can't travel through a vacuum. That's why you don't hear a motor screaming in pain in a vacuum.

[@Cskirt]

Good idea 👍. The nitrogen costs ~$150 for 10L and the container(dewar) was ~$200

[@LawpickingLocksmith]

@@Cskirt 40 years ago I bought a tray of 100 cassette motors, they were like 50c each. I watched about 20 burn out and eventually the rest got dumped. I also tried many liquids but the liquid nitrogen was always on my mind. Never even got a chance to buy some even at 3 times your price.

I'm so confused about the liquid butane not igniting, now I understand equal and opposite a little more

[@keeganhenderson24]

There probably wasn’t enough oxygen. Look up Stoccometric (nooo idea if I spelled that right) ratios. Basically the fuel to oxygen ratio needed for combustion and detonation. This is the principle used in ICEs for fuel injection volume. Pretty cool stuff I think

Put the motor in mercury

[@eddybash1342]

The problem is the resistance of the dielectric formed by the enamel of the copper wire. This does not resist high voltages even in a coolant.

[@Algo_de_Alguem]

good video

[@Stumpyoficial]

Man, your videos are very good, I thought to myself how long these motors would last at maximum voltage without burning out, can you tell me an average time?

[@Cskirt]

Once they start arcing they are gone in seconds, but you could run them on much higher than the rated voltage for a long time. How long it'll survive depends on the load and airflow/cooling

[@SSCchannel]

must be filled with Argon gas to prevent oxidation

[@-pigeon-]

you should try overvolting some nerf tuning motors(130 form factor, 11.1V rated voltage, the fastest ones i've seen go up to ~70000RPM), they're expensive asf though. Curious how fast they would go in liquid butane

[@Cskirt]

[@BillyYT40Malaysia]

Oh. This means i am right about a 15 year old psu on a 13 year old pc. My mom gave it 3 years ago. It was running the good old classic OS. Windows 7. The psu was a 750W 230V only psu. Yes, 230V is weird right now since power bars are 240V and so as psu. But it was from 15 years ago so what'd you expect? Anyways i plugged in the monitor and psu cable on to a 240V power bar and I didn't notice that at the back of the psu it says "230V ONLY". Then the monitor restarts 4 - 5 times but still works because i think 230V. Anyways while the monitor survives 240V the psu on the other hand did work but after just booted up to windows 7 amd clicked my cousins user (it was my cousins pc when my mom gave it), i heard a electrical spark at the pc then after that the pc randomly turned off. I was super confused and my cousin is really scared so he told to turn off the power switch that was connected to the pc and monitor. After a few minutes we have confirmed that is was the psu. It happened at Thursday, 7th November 2024
