12,000 RPM Fastest Lego Vacuum Engine | World record!!!

I hope you enjoyed the video!
It was quite hard pushing it to its limit, but it was worth it!
*At 5:08 I meant "break" and at 5:45 "vibrates"... I really don't know how this happened 🥲
- A tyre of a car going at 50 kmh or 30 mph spins like 26 times slower than this engine...
- The first version: • Testing a 8,100 rpm Le...
- The way I measured all the results is quite useful but not totally accurate... So it can sometimes deviate by a few rotations...
- If you didn't really understood how I calculated the speed:
It's quite simple...
I know that when the orange thing does one rotation, the propeller has completed 576. Then I stop the time measuring how long it takes the orange thing to do one rotation (the propeller 576). Then I divide 576 by the measured time, so I know how many rotations it does in one second. Finally I multiply it by 60 to get to rpm's (rotations per minute).

For you future projects i would recommend using WD40 for a lubricant, as water (in most cases) will slow you down due to it wanting to stick to itself and as well as the rotating parts. However, i understand if you don't like the idea of oily residue on your legos.

[@rctv9974]

Silicone lubricant is far better for lego

[@LucasDynamics]

I did it first with water and noticed how much it spread on my table, so I decided to stay with it... Maybe next time I'll try it...

[@jonathanroell8342]

What about graphite from a pencil? I’ve seen other people use it as a lubricant before

[@LucasDynamics]

@@jonathanroell8342 Good idea! Thanks!

wd40 isn;t really the best lube tbh, its only marginally better than water and is very short term something like bike chain lube would probably work best here

Use a rpm reading thing. The gears used to measure the rpm put a lot of drag on the system. You can hear there is a big difference with the rpm with and without

[@LucasDynamics]

Yeah, without it, it would be definitely faster!

[@ccoder4953]

There's another way you can estimate speed - sound. Record the audio with it spinning at a known speed. Put the audio in a audio program (like Audacity) and have it do a spectrogram. You should see a strong peak at the known speed. That corresponds to the speed (albeit in revolutions per second instead of minute) or a multiple of it. Then take the gears off and repeat. You should see that peak move, so now you can recalculate and get the speed.

[@Google_Corporation]

Worm gears are famously inefficient. Like 50% efficient. If he needs to record speed but needs a reduced output, use spur gears, as they're typically 99-99.9% efficient. I've had extremely low power systems with 300:1 spur gear reductions run totally fine, but one worm gear, regardless of the ratio, will kill the same motor.

@@LucasDynamics just use an IR laser to detect the revolutions.

usually, we use oil rather than water because water has a much higher surface tension on top of being more reactive with our traditional metal engine components, generating rust which weakens the components on top of their existing wear and tear a "dry" counterpart is graphite

A bit of silicone spray lube (jig-a-loo or similar) will save a lot of wear on your moving parts and likely help get higher rpm than water.

For a future version, perhaps you can get metal technic axles so they don't wear out quite as much? Also, someone below mentioned using an "rpm reading thing" for better speed due to decreased load on the shaft... if you do this, I also recommend using a wheel with a marking on it instead of the spinning tooth thingy, to minimize vibration.

Offsetting the rod by half a plate upwards or downwards could increase the efficiency, as it can't spin with an extra full plate underneath, but likely could with half of one. Just leave a 5 plate tall 2 stud wide hole in the side and fill it with the inverted axle hole with a plate on top and tile on bottom. Use a bracket to hold the axle holder outside.
